CNC lathe collision has great damage to the accuracy of the machine tool, and the influence on different types of machine tools is not the same. In general, the influence on the machine tool with weak rigidity is relatively large, such as horizontal lathe. Once the machine tool collides, the influence on the accuracy of the machine tool is fatal. Therefore, for high-precision CNC lathes, collisions must be eliminated. As long as the operator is careful and grasps certain anti-collision methods, collisions can be prevented and avoided.
The main reasons for the collision of CNC lathe are as follows:
1, the diameter and length of the tool input error;
2, the size of the workpiece and other related geometric dimensions input error and the initial position of the workpiece positioning error;
3. The workpiece coordinate system of the CNC lathe is set incorrectly, or the zero point of the machine tool is reset during the processing, and changes occur. Most of the machine tool collisions occur during the rapid movement of the machine tool. The hazards of collisions that occur at this time should be absolutely avoided.
Therefore, the operator should pay special attention to the initial stage of the execution of the program and the machine tool when replacing the tool. At this time, once the program is edited incorrectly, the diameter and length of the tool are input incorrectly, then it is easy to collide.
At the end of the program, the CNC axis of the retreating action sequence is wrong, then a collision may also occur.
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 has abnormal action, whether there is spark, whether there is noise and abnormal noise, whether there is vibration, whether there is a burning smell. Metal processing WeChat content is good, worthy of attention. If an abnormal situation is found, the program should be stopped immediately, and the machine can continue to work only after the machine problem is solved.
