1. Please pay attention to the features of stone CNC router, especially the spindle power. Some CNC stone router is only suitable for lower power processing, such as color plates, building models, small signs, three-dimensional crafts and other materials, this process has been popular for some time, but because of spindle power is too low, which will affect it’s scope of application. Another type is the high-power spindle, which is divided into two types, one is the large format stone CNC machine, the working size is generally more than one meter, but the accuracy of the machine generally poor, another one is moderate size stone CNC machine, this machine is generally used in fine processing and organic label production.
2. We must understand the CNC stone router performance and functionality, the spindle is very critical, because the spindle motors are generally not covered by the warranty, and the spindle need to work for long time, so if the spindle motor is not very good, it will affect the use of CNC stone router.
3. Another one is adjust range of the spindle speed, generally adjustable speed range is a few thousand to thirty thousand revolutions per minute, if the speed is not adjustable or adjustable speed lesser extent, then it shows that the scope of application of stone CNC machine on severely limited, because different materials must be carved in different carving head speed.
4. Stone CNC machine body manufacturing process: high-power machine body must be precise and stable when the job requirements, so the machine body should be used casting sculpture in order to ensure it’s precision and stability.
5. The CNC controller is generally divided into two types, one is that it only do the drive controller, and all of it’s operational work done by the computer, when the stone CNC router working, the computer wait, not a typesetting work. Another controller uses SBC or MCU control, this controller is actually a computer, so long as the stone CNC router start to work, the computer can immediately carry out other typesetting work, especially for a long time carving, the the advantage is particularly evident.
6. The ballscrew and guide rails are also important parts of CNC stone machine, a good screw and rail will ensure it’s accuracy and performance of CNC machine for a long time.
