What are the causes of collision of CNC lathe?

The collision of CNC lathe has great damage to the accuracy of machine tool, and the impact of different types of machine tools is also different. Generally speaking, the machine tool with weak rigidity has a great impact, such as horizontal lathe. Once the machine tool collides, the impact on the accuracy of machine tool is fatal. For high-precision CNC lathe, collision must be eliminated, and the operator must master the anti-collision method.

Causes of collision of CNC lathe:

1. Enter an error for the diameter and length of the tool.

2. The input fault of the workpiece scale and other related scales and the initial orientation positioning fault of the workpiece.

3. The workpiece coordinate system of the NC lathe is set wrongly, or the zero point of the machine tool is reset in the processing process, and the machine tool collision mostly occurs in the process of rapid movement of the machine tool. At this time, the collision is also particularly harmful, which should be prevented in time.

The operator should pay attention to the initial stage of the NC lathe performing the program and when the machine tool is changing the tool. Once the program editing is wrong and the tool diameter and length input is wrong, it is easy to bump. At the end of the program, if the tool retraction sequence of the NC axis is wrong, there may also be bumps.

In order to prevent the above bumps, the operator shall give full play to the functions of five senses when operating the CNC lathe, and investigate whether the machine tool has abnormal action, spark, noise and abnormal sound, vibration and scorching smell. The content of metal processing wechat is good and worthy of attention. In case of abnormal conditions, the program shall be stopped immediately. The machine tool can continue to operate only after the problem of standby machine is solved.
