4 Tips to solve Problems during CNC Machining Process

1. How to judge the good condition and the service life of the tool ? In the automatic machining process of the machine tool, it is necessary to hear the cutting sound. During the cutting process, we also should periodically check or touch the tool edge, and analyse according to the surface finish. 2. How to choose the corresponding tool according to the material characteristics? 1, in the process of processing, if the tool is not selected correctly, it will lead to unstable processing or failure in processing! And it affects efficiency and can’t make good quality. Therefore, it is very important to choose the tool. When we process the relatively hard material, we should use the tool with strong rigidity and strong tool tip. The machine should also be in low speed, slow feed, less back and other principles! When the processing material is relatively soft, such as aluminum alloy, nylon rod, copper and other materials, we can increase the speed, feed, the weight of knife, and use the corresponding alloy knife. In particular, if the feed table is slow, slag will be formed, and the work piece will be entangled without slag. This will greatly affect efficiency and quality! 3. How to make sure the process or the tool path does not affect the efficiency? The same knife should not be used repeatedly as many times as possible. The second step should be completed without the first knife. The order of the knife and the sequence of the program must be arranged according to the path when the conditions permit, and the compressed space should be compressed as much as possible. Reduce time, reduce unnecessary positioning error, and optimize the program again to achieve the best processing state without affecting the tool or quality! 4. How to deal with deformation when processing thin products? Such products are so difficult, and some may be divided into many processes to complete, according to product requirements, analyze and judge! Be sure to use low speed and slow feed ! Also, it is necessary to us e a tool with a small tip and a sharp blade. Axial clamping is also possible. If the radial is too tight, there will always be deformation!
