Things To Consider Before Buying A CNC Machine
This buying guide is specially prepared for catering your thoughts while buying a CNC engraving machine. Starter woodworkers must consider the following points for an accident-proof first-time experience.
1. Safety Features
Safety is that premium property on which any machine should be assessed. While working on a CNC machine, some safety points should be considered as it has got several hazards because it includes electrical wirings and heavy mechanical components. Ensure that the CNC machine you are buying must have an emergency stop, as it helps in immediately stopping the machine in case of an accident or fire breakout. It must have a heat dissipating system, which may include a temperature sensor too. It will keep an observatory eye on the temperature rise of the cutting tools during manufacturing. It will continually dissipate heat with the help of heat sinkers or external fans installed in the machine. An additional safety feature of optocouplers could also be incorporated as it controls sudden stops of the drill bits during machining; hence, protecting the cutting tool from any expected damage.
These features will not only safeguard you from any accident but will also enhance the lifetime of the CNC machine itself.
2. Type Of Your Projects
Before going to shop for a CNC, you should know what kind of work you will handle with this machine. Either you are a hobbyist worker and will use the device in only your leisure hours, or a beginner who is just starting woodworking from scratch.
If you are a hobbyist or a learner, then the CNC machine’s sturdiness should not be a consideration for you. If you are a beginner and you are buying a CNC to start learning. You may not possess any preliminary knowledge of CNC machining. You must go for a setup that comes pre-assembled and is comparatively easy to work with, but if you are a professional worker. You have to meet the specific target at the end of the day, then you must need a well-built, strong setup, gives you precision and can handle bulk production.
3. Offline Controller Capacity
The offline controller helps you perform your job without connecting the router each time with your controller. Mostly offline controllers come with a 128 to 1G storage capacity, which is quite sufficient for beginners to moderate level woodworkers. With the help of an offline controller, you can download plenty of the jobs, save it in the memory, and can work on them without the hassle of connecting each time with the computer.
4. Dust Port
Dust port or you can call it safety baffles, containers that contain wooden waste within them. The dust port is essential as they encourage a debris-free environment and maintains a hygienic atmosphere. A buyer should check that whether the CNC machine has the feature of a dust port or not. It also helps to protect the woodworker from the flying wooden chips built during manufacturing processes. It also helps in maintaining a clean workshop.
5. After-Sales Services
After-sales service is such an important point to take care of while buying a CNC machine. Whether you are a starter or a professional good after-sales service is essential for everyone because there comes time when a new setup does not work as expected after unboxing. Then only a good after-sales servicing will help you get the machine fixed.
At times good after-sales service comes with high-end brands, and sometimes it is just the opposite of the general rule of thumb.
While buying a CNC engraving machine, do check up on the status of its upgrading ability. Mostly when beginners buy a setup, budget is the most significant restriction in purchasing a high-end process. Not only budget, their due to the low volume production they might not need accessories like dust port, proper heat management system, collet or end mill holders in initial days but when they think of expanding their volume these things must come in use. Hence, CNC is not a repetitive buying product; therefore, money should be invested in a particular product, which gives you the upgrading ability as time passes and production volume increases.
Budget is the final and the highest part of consideration while buying a CNC machine. This list has provided you with the low priced DIY CNC machines and high-end complicated professional machines. Now you need to decide which of these go with your budget.
