In the process of CNC machining, the processed products are often counterproductive for some reason or another, and many friends who have just entered the industry often encounter many problems and failures, so what problems will often occur in CNC machining? Let's learn together. CNC machining often has the following problems:

1. The workpiece produces a taper size head phenomenon:

The placement level of the machine tool is not adjusted properly, one is high and the other is low, resulting in unstable placement. When turning the long axis, the contribution material is relatively hard, and the tool eats the knife deeply, resulting in the phenomenon of knife yielding, and the tailstock thimble and the spindle are not concentric.

2. The arc processing effect is not ideal, and the size is not in place:

The overlapping of vibration frequencies causes resonance and processing technology; the parameter setting is unreasonable, the feed speed is too large, and the arc processing is out of step; the looseness caused by the large screw gap or the loss of step caused by the screw is too tight, and the synchronous belt is worn.

3. Each process of the workpiece has the phenomenon of increasing or decreasing:

Programming errors; unreasonable system parameter settings; improper configuration settings; regular and periodic changes in mechanical transmission components.

4. The dimensional changes caused by the system are unstable:

The system parameter setting is unreasonable; the working voltage is unstable; the system is affected by external interference, causing the system to lose synchronization, and capacitors have been added, but the impedance between the system and the driver does not match, resulting in loss of useful signals, and abnormal signal transmission between the system and the driver ; System damage or internal failure.

To sum up, I have made a brief introduction to the problems that often occur in CNC machining. I hope it can help you. You must pay attention to the CNC machining process, and do inspections and preparations in advance.
