Collision of a machine tool greatly damages the accuracy of the machine tool, and it also affects different types of machine tools. Generally speaking, it has a greater impact on a machine tool with less rigidity. Therefore, for high-precision CNC lathes, collisions must be avoided. As long as the operator is careful and masters certain anti-collision methods, collisions can be completely prevented and avoided.

The main reasons for the collision are: first, the wrong input of the tool diameter and length; second, the wrong input of the workpiece size and other related geometric dimensions, and the wrong initial positioning of the workpiece; third, the wrong setting of the workpiece coordinate system Or, the zero point of the machine tool is reset during the machining process and changes occur. Most of the machine tool collisions occur during the rapid movement of the machine tool. At this time, the collision hazards are also the greatest and should be absolutely avoided. Therefore, the operator should pay special attention to the initial stage of the machine tool execution and the machine tool replacement. At this time, if the program is edited incorrectly, the diameter and length of the tool are incorrectly entered, then collision is easy. At the end of the program, the sequence of the retracting motion of the CNC axis is wrong, and collision may occur.

In order to avoid the above-mentioned collisions, when operating the machine tool, the operator must give full play to the functions of the five senses, and observe whether the machine tool has abnormal movements, sparks, noises and abnormal sounds, vibrations, and burnt smell. When abnormal conditions are found, the program should be stopped immediately, and the machine can continue to work only after the standby bed problem is solved.
