Analyze the causes of collision of CNC lathe?

The collision of NC lathe has great damage to the accuracy of machine tool, and the impact of different types of machine tools is also different. Generally speaking, it has a great impact on machine tool, such as horizontal lathe. Once the collision of machine tool occurs, the impact on the accuracy of machine tool is fatal. Therefore, for high-precision CNC lathe, collision must be eliminated. As long as the operator is careful and master certain anti-collision methods, collision can be prevented and prevented.

The causes of collision of CNC lathe are analyzed as follows:

1. Input 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 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 particularly harmful and should be prevented in time.

The operator should pay attention to the initial stage of the program and the tool change of the machine tool. At this moment, 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, when operating the CNC lathe, the operator shall give full play to the functions of five senses, and investigate whether the machine tool has abnormal action, sparks, 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.
