Causes of bumps on CNC lathes


The collision of the CNC lathe has great damage to the accuracy of the machine tool. The impact on different types of machine tools is also different. Generally speaking, the machine tool with low rigidity has a greater impact, such as horizontal lathes. Once the machine tool has a collision, it will affect the machine tool. The accuracy impact is fatal. Therefore, for high-precision CNC lathes, bumps must be eradicated. As long as the operator is careful and masters certain methods to prevent bumps, bumps can be prevented and prevented. The analysis of the reasons for the collision of the CNC lathe is as follows:

1. The input of the diameter and length of the tool is wrong.

2. Incorrect input of the dimensions of the workpiece and other related geometric dimensions, as well as errors in the initial orientation of the workpiece.

3. The workpiece coordinate system of the CNC lathe is set incorrectly, or the zero point of the machine tool is reset during the machining process and changes occur. Most of the machine tool bumps occur during the rapid movement of the machine tool. At this time, the bumps that occur are also the most harmful and should be prevented.

Therefore, the operator should pay special attention to the CNC lathe in the initial stage of performing the program and when the machine tool is changing the tool. At this moment, once the program is edited incorrectly, the diameter and length of the tool are entered incorrectly, then it is easy to bump. At the end of the program, if the CNC axis retracts the tool in an incorrect sequence, then collisions may also occur. In order to prevent the above bumps, the operator should give full play to the functions of the facial features when operating the CNC lathe, and investigate whether the machine tool has abnormal movements, sparks, noise and abnormal noise, vibrations, and burning smells. The metal processing WeChat content is good and worthy of attention. If an abnormal situation is found, the program should be stopped immediately. After the standby bed problem is solved, the machine tool can continue to operate.
