Myrtle Beach can be awesome and annoying — it depends on what you’re into. Here’s a rundown of why some people find Myrtle Beach annoying:
1. Tourist Overload
During peak season (spring break, summer), the city is swamped with tourists. Roads, restaurants, and beaches are packed. Locals often feel pushed out of their own town.
2. Terrible Traffic
Highway 17 and Kings Highway become gridlocked daily during tourist season. Even short drives can turn into frustrating crawls.
3. Tacky Commercialism
The area is filled with chain restaurants, Ripley’s attractions, wax museums, mini golf courses, and gift shops selling cheap beach junk. It can feel a bit like a theme park gone wild.
4. Crime in Some Areas
Certain parts of Myrtle Beach, especially near the boardwalk, have higher crime rates — petty theft, drug activity, or aggressive panhandling can be issues.
5. Seasonal Economy
Jobs are heavily tied to tourism, meaning many are low-paying, seasonal, or tip-based. The off-season can feel like a ghost town for workers.
6. Loud and Rowdy Nights
Nightlife brings noise, drunk tourists, and obnoxious behavior. Spring break and bike weeks can be especially chaotic.
7. Constant Construction
To keep up with growth and tourism, Myrtle Beach is almost always building or remodeling something. That means dust, noise, and detours.
8. Limited Cultural Offerings
Unless you go hunting for them, art galleries, music venues, and alternative culture spots are few and far between compared to bigger cities.
9. Touristy Prices
Everything near the beach is overpriced. Locals often have to drive inland just to get normal grocery or restaurant prices.
10. Bad Drivers
Myrtle Beach has a reputation for reckless or confused drivers — especially tourists unfamiliar with local roads or who don’t use turn signals… ever.
11. Bike Week Chaos
Harley Week and Atlantic Beach Bikefest turn the town into a nonstop roar of engines and parties. Locals either love it or absolutely hate it.
12. Souvenir Store Hell
You can’t drive a block without passing a Wings, Eagles, or Pacific store. It gets old fast.
13. Poor City Planning
Some areas feel disconnected or poorly designed — with minimal sidewalks, strange zoning, and chaotic development patterns.
14. Sand Gets Everywhere
Living near the beach sounds great until you’re vacuuming sand out of your car and shoes every day.
15. Hard to Find Peace and Quiet
Unless you’re far inland or on a private part of the coast, finding calm, uncrowded nature is tough — even the “quiet” spots attract people.
If you’re a local, you probably know the love/hate balance already. If you’re considering moving there, this is the kind of stuff that bugs people over time.
To generate a CAM program (G-code) from an STL file in FreeCAD, you’ll need to first convert the STL mesh into a solid model, then create a CAM job and define the machining parameters, and finally, generate the G-code.
Here’s a step-by-step guide:
1. Import and Convert STL to Solid:
Import: File > Import > Select your STL file.
Switch to Part Workbench: Go to the top menu and select Part Workbench.
Create Shape: Select the imported mesh and choose Part > Create Shape from Mesh.
Convert to Solid: Select the newly created shape and choose Part > Convert to Solid.
2. Prepare for CAM (Optional):
Refine (Optional): If you want to make the solid model cleaner or more accurate, you can refine it: Part > Refine Shape.
Create Body (Part Design Workbench): For easier editing, you can create a Body using Part Design > Create Body. This will also add a BaseFeature.
3. Switch to CAM Workbench and Define Job:
Switch to CAM Workbench: Go to the top menu and select CAM Workbench.
Create Job: Click on the “Job” button and select your solid model (the one you converted from the STL file).
Define Job Parameters: Set the material, tool, and other machining parameters according to your CNC machine and project requirements.
4. Define Operations:
Choose Operations: Select the operations you need for your project (e.g., pocketing, drilling, profiling).
Define Operation Parameters: Set the parameters for each operation (e.g., tool path, cut depth, speed).
5. Generate G-Code:
Generate G-Code: After defining all the operations, use the CAM tool to generate the G-code file.
Export G-Code: Export the G-code file to a format compatible with your CNC machine.
Important Considerations:
Accuracy: STL files are often not perfectly accurate representations of a solid model. Refining the solid model after conversion can improve machining accuracy.
CAM Software: FreeCAD’s CAM Workbench can generate G-code, but it might require a bit of learning to master the various operations and parameters.
Post-Processing: FreeCAD can generate G-code in its own dialect, which needs to be translated to the correct format for your CNC machine. This is done through post-processing.
Okay, let’s get started with setting up public-pool on your Xubuntu Bitcoin node. public-pool is a relatively lightweight and straightforward mining pool software, often favored for smaller setups and its ease of use compared to more complex options like yiimp or NOMP.
Here’s a step-by-step guide to get you going. Keep in mind that this assumes you have a basic understanding of Linux command-line operations.
Prerequisites:
Your Xubuntu Bitcoin Node is Running and Fully Synced: Ensure your bitcoind is running and has downloaded the entire blockchain.
Basic Linux Command-Line Knowledge: You’ll be working in the terminal.
git Installed: You’ll need git to clone the public-pool repository. If not installed, you can install it with: Bashsudo apt update sudo apt install git -y
Node.js and npm (or yarn) Installed:public-pool is built using Node.js. If you don’t have them, install them: Bashsudo apt update sudo apt install nodejs npm -y You might want to install a specific version of Node.js using nvm (Node Version Manager) for better compatibility. Check the public-pool documentation for recommended versions if available.
screen or tmux (Optional but Recommended): These tools allow you to run public-pool in the background and keep it running even if you close your terminal session. Install with: Bashsudo apt install screen -y # or sudo apt install tmux -y
Installation and Configuration of public-pool:
Clone the public-pool Repository: Open your terminal in Xubuntu and navigate to a directory where you want to install public-pool (e.g., your home directory or a dedicated mining folder). Then, clone the repository. The repository URL might vary depending on the specific fork or source. A common one is: Bashgit clone https://github.com/TheSerapher/public-pool.git cd public-pool(Note: This is based on a common source for public-pool. If you found it elsewhere, use that repository URL.)
Install Dependencies: Navigate into the public-pool directory and install the necessary Node.js modules using npm: Bashnpm install Alternatively, if you prefer yarn: Bashyarn install
Configure public-pool: You’ll need to create a configuration file. Look for a sample configuration file (e.g., config.sample.json or similar) in the public-pool directory. Copy it and rename it to config.json: Bashcp config.sample.json config.json nano config.json Now, edit the config.json file with your specific settings:
rpc (Bitcoin Core RPC Settings): JSON"rpc": { "host": "localhost", "port": 8332, "user": "your_rpc_user", "password": "your_rpc_password" }, Replace "your_rpc_user" and "your_rpc_password" with the rpcuser and rpcpassword you have set in your bitcoin.conf file.
poolServer (Pool Listening Address and Port): JSON"poolServer": { "listen": "0.0.0.0", // Listen on all interfaces "port": 3333, // Default mining port "ssl": false, // Set to true for SSL (requires certificates) "sslPort": 443 // SSL port }, Adjust the listen address and port as needed. If you plan to make your pool publicly accessible, 0.0.0.0 is usually the way to go.
payout (Payout Settings): JSON"payout": { "interval": 3600, // Payout interval in seconds (e.g., 3600 for hourly) "threshold": 0.001, // Minimum payout amount in BTC "address": "your_bitcoin_address" // Your Bitcoin payout address }, Set the payout interval, minimum payout threshold, and your own Bitcoin address where the solo mining rewards should be sent.
Other Settings: Review the rest of the config.json file for other settings you might want to adjust, such as donation addresses, block unlocker settings, etc.
Save and close the config.json file (in nano, press Ctrl+X, then Y, then Enter).
Start public-pool: Navigate back to the public-pool directory in your terminal and start the pool server: Bashnode stratum_server.js You should see output indicating that the stratum server has started.
Run in the Background (Recommended): To keep public-pool running even after you close your terminal, use screen or tmux:
Using screen: Bashscreen -S publicpool node stratum_server.js # Press Ctrl+A then Ctrl+D to detach from the screen session # To re-attach later: screen -r publicpool
Using tmux: Bashtmux new -s publicpool node stratum_server.js # Press Ctrl+B then D to detach from the tmux session # To re-attach later: tmux attach -t publicpool
Configure Your Miners: Now, you need to configure your Antminer S19s, LVO7, and Nerdaxe to point to your public-pool server. In your miners’ configuration settings, you will typically need to enter:
Pool URL: The IP address of your Xubuntu machine (if it’s on the same network, it might be its local IP address; if you need external access, it will be your public IP address) followed by the port you configured in config.json (e.g., your_ip_address:3333).
Worker Name: You can usually set a worker name to identify your miners (e.g., s19.1, lvo7.a, nerdaxe.1).
Password: Often, the password can be anything (e.g., x).
Monitor Your Pool:public-pool might have a basic web interface for monitoring. Check the documentation or the console output when you start the server for the web interface URL and port (it’s often on a different port than the mining port).
Important Considerations for Solo Mining with a Public Pool Setup:
“Public” in public-pool: While the name suggests public, you are configuring it to be your pool for solo mining. You don’t need to advertise it or allow others to connect. The “public” refers to its capability to operate as a public pool if desired.
Firewall: If your Xubuntu machine has a firewall enabled (e.g., ufw), you might need to open the mining port (e.g., 3333) to allow your miners to connect. Bashsudo ufw allow 3333
Network Configuration: If your miners are on a different network than your Xubuntu machine, you’ll need to ensure proper network routing and port forwarding on your router to allow the miners to reach your pool server.
Resource Usage: Running a mining pool server and a full Bitcoin node on the same machine can be resource-intensive. Monitor your VM’s CPU, RAM, and network usage.
Luck: Remember that solo mining success is entirely dependent on your hashing power and luck. There’s no guarantee of finding blocks.
This guide should give you a solid starting point for setting up public-pool for solo mining on your Xubuntu Bitcoin node. Remember to consult the specific documentation for the version of public-pool you are using for any additional configuration options or troubleshooting tips. Good luck!

DIY S9 HiveOS (Antminer S9) Installation Guide (with a Touch of Caution!)
I recently embarked on a personal project: installing HiveOS on my S9 miner. While I initially experimented with the pre-installed BraiinsOS, I found it a bit underwhelming. Suspecting a less-than-ideal installation, I decided to take matters into my own hands and give HiveOS a try.
Here’s a step-by-step guide based on my own successful installation:
Prepare your SD Card:
Obtain an 8GB SD card.
Format the SD card with a single 8GB partition.
Download HiveOS:
Download the HiveOS SD image archive from the official website.
Extract the contents of the archive into a separate folder.
Transfer Files to SD Card:
Copy the extracted files (not the folder itself) to the root directory of your 8GB SD card.
Switch to SD Card Boot:
Power down your S9 miner.
Locate the jumper on the miner’s control board.
Carefully reposition the jumper (J4) to enable booting from the SD card.
Insert SD Card & Power On:
Insert the prepared SD card into the S9 miner.
Power on the miner.
Observe the fault and normal lights. They should blink together in sync when it is done installing. let the machine sit for a few minutes.
Initial Run-In (Hands-Off!):
Once the miner has finished the instal of the new hiveon firmware and the two leds are blinking in a on/off/on/off pattern, power it off.
Remove the SD card and change jumper j4 back so it will boot from the board instead of sd card.
Power on the miner again.
Crucially, leave it alone for about an hour.
You can access the web firmware on your local network, but resist the urge to make any changes!
Autotune & Configuration:
Allow the miner to autotune its settings.
You can monitor the autotune progress in the system logs or manually fine-tune chip settings under the configuration menu.
Log in using the default credentials: username ‘root’ and password ‘root@’.
Security First!
Immediately change the default password.
Write down your new password in a secure location.
HiveOS Configuration:
Choose your preferred configuration method:
Configure your miner through the HiveOS website.
Alternatively, configure it directly through the web interface on your local network.
Congratulations!
You’ve successfully installed HiveOS on your S9 miner.
Feel free to further customize settings or adjust your power profile to optimize performance.
Note: This guide is based on my personal experience. While I believe it to be accurate, individual results may vary. Proceed with caution and always refer to the official HiveOS documentation for the most up-to-date and reliable information.**
Cryptocurrency mining, a process that involves using powerful computers to solve complex mathematical problems in exchange for rewards in the form of cryptocurrency, has evolved significantly since its inception. This article delves into the intricacies of mining Dogecoin, Bitcoin, and Litecoin, exploring their unique characteristics, challenges, and the evolving technological landscape.
Bitcoin: The Pioneer of Cryptocurrency Mining
Bitcoin, the first and most well-known cryptocurrency, employs a mining process based on the SHA-256 hashing algorithm. Initially, miners could utilize their personal computers with powerful graphics cards (GPUs) to participate in the mining process. However, as the Bitcoin network grew and the difficulty of mining increased, specialized hardware known as Application-Specific Integrated Circuits (ASICs) became necessary for efficient mining.
ASICs are designed specifically for Bitcoin mining, offering significantly higher hash rates (the speed at which a miner can solve cryptographic problems) compared to GPUs. This has led to a centralization of Bitcoin mining power, with large mining pools and corporations dominating the landscape.
Challenges Facing Bitcoin Mining:

TIMING ===== 24 degrees BTDC @ 3000rpm. NGK BPR4HS – gap 0.6mm (0.025 in) Points gap should be set to 0.3mm (0.012 in) if hard to start but will start and run HARD if clutched, you have the timing wrong! i.e. reset the points gap – closer. You are opening too early and the maximum is 0.4mm (0.16 in) If possible, get a dial gauge and meter and ensure it opens exactly when the mark aligns with the notch on the cover. Timing light shining on the mark will show if you are out. If always hard to start and everything else is spot on, replace points. If still no good, replace condenser. If all is correct, you should be able to walk up to a cold machine, flip the choke on, touch NOTHING and kick it. It will start first or second kick.
CLUTCH adjustment ============ Take the clutch cover off – note engine oil dripping onto your feet. Loosen locknut. Run the centre screw in until it just hits the pushrod (you will feel it) Tighten locknut. Too loose and it will not turn the engine over. Too tight and the kick-starter will not return. Idle @ 1400rpm, engages @ 2500rpm, fully locked @ 3000rpm. Do minor adjustments to suit your little person. Adjustment of the clutch is recommended so that the bike rolls freely in gear. This lets the motor gain a few revs before engagement and makes the shift into gear smoother. Add oil to engine again… Test by starting up, letting it idle and pushing into 2nd. It should NOT move off until the throttle is turned.
CARBURETTOR ========= Mikuni VM12SC, float height 25mm, air screw 1-1/4 turns out Make sure you fit a fuel filter! They did not come with one. if fuel is coming out of the overflow pipe too much, you have float setting too low, e.g. 23mm instead of 25mm. Yes it has two tiny little pilot jets, not one!. Blow out the tiny jets, blow out the main, blow out the other two holes. Also, adjust the throttle cable up at the handlebars to remove any slack.
OIL == Today’s 10W/30 (SAE80W) motor oils are ideal. There is a bolt in the side of the r/h case. Remove; fill until it comes out of the bolt hole.
The CCI injection container is for boring normal 2-stroke oil. Fuel should be plain high-octane unleaded. NOT premixed.
LOW POWER ======== Clean out the exhaust – it gets blocked with crud with age. Compression test should be circa 100PSI. There may be restrictor plates between carburettor and head. Also in head to exhaust – remove them. Give it a new plug and fresh fuel.
1st GEAR ====== Transmission is 2nd-neutral-1st (down-is-second, middle is neutral, up-is-first) However 1st is blanked-off normally. 1st is a very low gear. Pull the right side cover off. With the cover off you can look at the shift lever. The flat arm has a rectangular slot that is only half-width, rather than full-width. You’ll see where the section has been blanked off. It’s got an oblong cut one way. Make a second oblong space the other way and now you have 1st gear available. 1st is very, very low, but will pull up mountains.

Thanks Vic – I did the mod last night and it works great. The first gear is awesome – before it would hardly pull me – now I can do wheelies. My boy hasn’t riden it yet but he will be very happy ( just hope he doesn’t learn to get the front wheel up when mom is watching ! ). I would offer some guidance to others doing the mod : 1) Remove the foot peg/sidestand assembly as this blocks access to the shift mechanism. It’s easy to do and makes the job easier. 2) Undo the nut and pull the rear brake lever off its post as well – just more room to work. 3) Mark the kickstart lever/shaft relationship to make sure the kickstart is correctly loaded on reassembly. 4) Remove kickstart lever and oil feed pipe banjo bolt. Drain oil. 5) Remove clutch cover. 6) Remove engine casing. Note order for clutch parts. 7) Remove spring and clip plate from selector. 8) Grind away the material. I put paper towels all round the area and behind the selector to catch the grindings. Put the spring and clip plate back on temporarily to check that the selector goes into the new gear, and sits in the notch in the clip plate. ( By using the normal gear lever ) 9) Clean up well, I rinsed with WD40. 10) Remove kickstart stop bolt. 11) Put clutch together and engine case on ( lining up the clutch mechanism ). It may help to turn the engine over with the kick lever to get the oil pump gear to mate. Put clutch cover. Line up kickstart lever with the marks you made earlier and fit clamp bolt, push down and put in stop bolt. Bolt on the clutch cover and other bits ( don’t forget the oil pump feed line). Put in oil. Ride. I’m going to change the oil again just in case I got some filings in there.
It is very easy – it took me a couple hours, but only because I tried to do it without removing the pegs etc.
ok heres is a list of mods that will make the jr50 a pw50 killer
first take out the 2nd pilot jet.
buy the fmf fatty pipe and power core silencer for it on ebay or somewhere,
drill 4- 1/4 holes in the end of the airbox cover around the 3/4 OEM hole, buy a 12 tooth aluminum front sprocket sunline makes one so does moose and a 28 tooth aluminum moose rear sprocket (less rotating mass really makes a big difference in these bikes
next buy honda crf50 aftermarket aluminum rims and have buchanon spokes make spokes for em (again less rotating mass over heavy steel rims, ) ebay you can win a set for 40 to 60 bucks
activate 1st gear
++++ mill the head take off the entire lip on the head you can do this yourself with a belt sander or have it machined this will up the compression to around 10-1,+++
next do a port job on the intake and exhuast do yourself with a dremel ruffing up the intake
and smooth the exhuast
go EBC brake pads lighter than OEM
i also modified crf50 handlebars to fit on the oem triple clamp by drilling 2 new holes i used the OEM honda throttle assembly better and quicker throttle response
lightened the flywheel
use pirelli tires they are lighter and sticky but wear out twice as fast as dunlops
run 91 octane gas with a little octane boost in it about a 1/4 bottle for every 5 gallons
take out the 2 shorter front springs and replace with 2 longer front springs( each tube has 1 short one long spring keep the 2 old long ones and add 2 new long ones but note you will have 2 extra short ones because you buy both together, this works good for jumping
you can also just drill out the stock rear sprocket for less weight
take off the chain guard and kickstand and everything else you dont need horsepower to weight ratio is the most critical things on these bikes
works connection makes footpeg extenders and they just need to be tack welded onto the existing pegs for wider pegs you can even shave the plastics a little to help with weight.
you can also buy a 20 mill carb that will wake them up
you can take off the oil pump and bottle and run pre mix but i dont recommend it on this bike,
you can easily shave 20 lbs and more off this bike and that will make it rip and out run and modded pw50 even with a QT shaft.
also use a wiseco piston and you can bore 2mm over to turn it into a 55cc motor but i would only go 1mm over after 2mm you can not rebore
i also have been thinking of modding one to accept crf50 triple clamps and forks by welding the downtube onto a jr frame and using kids mountain bike adjustable shocks to the rear
ill let you know if i do as soon as i find a decent deal on
A recent project here in the shop was to 3d print this motor coupler part for the ShopSmith bandsaw accessory because we needed it! it’s also going to allow us to use the belt sander attachment with a quick release change out. If you have a 3d printer or know about a cool shop that has one with some open time on the machine, you could have prototype and functional parts designed and printed in hours!
We have this item for sale in our webstore! The price is $24 USD and free shipping to the USA People.

In the world of modern manufacturing, precision and efficiency are paramount. As industries continue to evolve, so do the technologies that drive them. One such technology that has become indispensable in various sectors is Computer Numerical Control (CNC) machining. While traditional 3-axis CNC machines have been the workhorse of many manufacturing operations, the introduction of 4-axis CNC machining has opened up new possibilities and increased capabilities, making it a valuable asset for complex and intricate production tasks. In this article, we’ll explore what 4-axis CNC machining is, how it works, its advantages, applications, and how it compares to other CNC technologies.
Understanding 4-Axis CNC Machining
Before diving into the intricacies of 4-axis CNC machining, it’s essential to understand the basic concept of CNC machining itself. CNC machining is a manufacturing process that utilizes computerized controls to operate and manipulate machine tools, such as lathes, mills, and routers, to create precise parts and components from raw materials. The “axis” in CNC machining refers to the number of directions in which the machine’s cutting tools can move.
In traditional 3-axis CNC machining, the machine’s cutting tool moves along three linear axes—X, Y, and Z. The X-axis allows for movement left and right, the Y-axis facilitates movement forward and backward, and the Z-axis enables movement up and down. While this setup is sufficient for producing many parts, it has limitations when it comes to creating more complex geometries and features.
This is where 4-axis CNC machining comes into play. A 4-axis CNC machine adds a fourth rotational axis, typically referred to as the A-axis, which allows the workpiece to rotate around the X-axis. This added degree of movement provides greater flexibility and capability, enabling the machine to perform operations that would be challenging or impossible with just three axes.
How 4-Axis CNC Machining Works
The addition of the fourth axis in 4-axis CNC machining allows the machine to work on multiple sides of a workpiece without the need to reposition it manually. This rotational axis is typically mounted on a rotary table, which is integrated into the CNC machine. The workpiece is secured to the rotary table, and as the machine operates, it can rotate the workpiece around the A-axis while simultaneously performing cutting, drilling, or milling operations along the X, Y, and Z axes.
For example, imagine you need to machine a cylindrical part with complex features on multiple sides. With a 3-axis machine, you would need to stop the operation, reposition the workpiece, and then restart the machining process for each side. This not only adds time and labor but also increases the risk of errors due to misalignment. With a 4-axis CNC machine, the workpiece can be rotated automatically, allowing the machine to perform continuous operations on multiple sides with a single setup. This results in higher accuracy, reduced production time, and lower labor costs.
Advantages of 4-Axis CNC Machining
The benefits of 4-axis CNC machining are numerous, making it an attractive option for many manufacturers. Here are some of the key advantages:
Increased Flexibility: The ability to rotate the workpiece provides access to multiple sides and angles, allowing for the creation of more complex geometries and features that would be difficult or impossible to achieve with a 3-axis machine.
Improved Accuracy: With 4-axis machining, there’s no need to manually reposition the workpiece between operations, reducing the risk of misalignment and ensuring greater precision in the final product.
Reduced Production Time: By eliminating the need for multiple setups and manual repositioning, 4-axis CNC machining can significantly reduce production time, leading to faster turnaround times for projects.
Cost Efficiency: While 4-axis CNC machines are generally more expensive than their 3-axis counterparts, the increased efficiency and reduced labor costs can lead to substantial savings in the long run, especially for high-volume production runs.
Enhanced Surface Finishes: The continuous movement and smooth transitions enabled by the fourth axis can result in superior surface finishes, reducing the need for additional finishing processes.
Versatility: 4-axis CNC machines can handle a wide range of materials, from metals and plastics to wood and composites, making them suitable for a variety of industries, including aerospace, automotive, medical, and consumer electronics.

4-Axis CNC Machining vs. 3-Axis and 5-Axis Machining
While 4-axis CNC machining offers significant advantages over traditional 3-axis machining, it’s essential to understand how it compares to other CNC technologies, particularly 3-axis and 5-axis machining.
3-Axis CNC Machining: As mentioned earlier, 3-axis CNC machines operate along three linear axes (X, Y, and Z). They are suitable for a wide range of simple to moderately complex parts but are limited when it comes to creating intricate geometries or working on multiple sides of a workpiece. While 3-axis machines are generally more affordable and easier to program, they require multiple setups and repositioning for more complex tasks, which can increase production time and the risk of errors.
4-Axis CNC Machining: By adding a rotational axis, 4-axis CNC machines overcome some of the limitations of 3-axis machines. They offer greater flexibility, improved accuracy, and reduced production time, making them suitable for more complex parts and higher-volume production. However, they are still limited compared to 5-axis machines in terms of the range of motion and the ability to access all sides of a workpiece without repositioning.
5-Axis CNC Machining: A 5-axis CNC machine adds two rotational axes (usually A and B) to the three linear axes, allowing the cutting tool to approach the workpiece from virtually any angle. This provides the ultimate in flexibility and precision, enabling the creation of highly complex parts with intricate details and smooth transitions. However, 5-axis CNC machines are more expensive, more challenging to program, and often require specialized tooling and software. They are typically reserved for the most demanding applications, such as aerospace and high-end medical device manufacturing.
In summary, 4-axis CNC machining strikes a balance between the simplicity and cost-effectiveness of 3-axis machining and the advanced capabilities of 5-axis machining. It offers a significant upgrade in terms of flexibility, accuracy, and efficiency, making it a valuable tool for many manufacturing applications.
