Numerical control lathe can process parts with small surface roughness, not only because of the rigidity of the machine tool and high manufacturing accuracy, but also because it has constant linear velocity cutting function. The surface roughness depends on the feed speed and cutting speed when the material, precision and tool are specified.

CNC lathe collision has great damage to the accuracy of the machine tool, for different types of machine tool impact is not the same, in general, for the rigidity of the machine tool is not strong impact, such as horizontal lathe, once the machine tool collision, the impact on the accuracy of the machine tool is fatal. So for high precision CNC lathe, collision to put an end to, as long as the operator is careful and master the anti-collision method, collision can be prevented and avoided.

CNC lathe custom manufacturers talk about the main reasons for the collision of CNC lathe analysis is as follows:

1, the diameter and length of the tool input error;

2, the size of the workpiece and other relevant geometric dimension input error and the initial position of the workpiece positioning error;

3, CNC lathe workpiece coordinate system is set wrong, or the zero point of the machine tool is reset in the process of processing, and changes occur, machine tool collision mostly occurs in the process of rapid machine tool movement, at this time the collision harm is also large, should be avoided.

So the operator should pay special attention to the CNC lathe in the initial stage of the execution of the program and when the machine tool is replaced, once the program editing error, the diameter and length of the tool input error, then it is easy to collision.

In order to avoid the collision, the operator in the operation of the CNC lathe, to give full play to the function of the five senses, observe whether the machine tool has abnormal action, there is no spark, there is no noise and abnormal sound, there is no vibration, there is no burning taste. Metal processing wechat content is good, worthy of attention. Find abnormal situation should stop the program immediately, until the problem of the machine tool is solved, the machine tool can continue to work.
