Briefly Describe the Main Reasons for Collision of CNC Lathes

CNC lathes can process parts with small surface roughness, not only because of the good rigidity and high manufacturing precision of the machine tool, but also because it has a constant linear speed cutting function. When the material, fine turning allowance and tool are fixed, the surface roughness depends on the feed speed and cutting speed.

Collision of CNC lathes has a great damage to the precision of the machine tool, and the impact on different types of machine tools is also different. Generally speaking, the impact on machine tools with weak rigidity is greater. For example, once a horizontal lathe collides with the machine tool, the impact on the precision of the machine tool is fatal. Therefore, for high-precision CNC lathes, collisions must be eliminated. As long as the operator is careful and masters the anti-collision method, the collision can be prevented and avoided.

The main reasons for the collision of CNC lathes are analyzed as follows:

1. The diameter and length of the tool are input incorrectly;

2. The size of the workpiece and other related geometric dimensions are input incorrectly, and the initial position positioning of the workpiece is incorrect;

3. The workpiece coordinate system of the CNC lathe is set incorrectly, or the machine tool zero point is reset during the processing process and changes.

Most machine tool collisions occur during the rapid movement of the machine tool. The harm of collisions at this time is also great and should be avoided. Therefore, the operator should pay special attention to the initial stage of the CNC lathe execution of the program and when the machine tool is changing the tool. Once the program editing is wrong and the diameter and length of the tool are input incorrectly, it is easy to collide. In order to avoid the above collisions, the operator should give full play to the functions of the five senses when operating the CNC lathe, and observe whether the machine tool has abnormal movements, sparks, noise and abnormal sounds, vibrations, and burning smells. If an abnormal situation is found in metal processing, the program should be stopped immediately, and the machine tool can continue to work after the machine tool problem is solved.
