Finish machining of parts

 

After the trial cutting of the first piece of parts, it is necessary to carry out mass production, but the qualification of the first piece does not mean that the whole batch of parts will be qualified, because, in the processing process, the cutting tools will be worn due to different processing materials. The processing materials are soft, the tool wear is small, the processing materials are hard, and the tool wear is fast. Therefore, in the processing process, it is necessary to check frequently, and increase and reduce the tool compensation value in time, to ensure that the parts are qualified.

Experience in preventing machine tools from collision

 

Machine tool collision is great damage to the accuracy of machine tools, and the impact on different types of machine tools is also different. Generally speaking, it has a great impact on machine tools with weak rigidity. Therefore, for high-precision CNC lathes, collision must be eliminated. As long as the operator is careful and masters certain anti-collision methods, a collision can be prevented and avoided.

 

The main reason for the collision is:

 

Wrong input of tool diameter and length;

 

Wrong input of the size of the workpiece and other relevant geometric dimensions and wrong positioning of the initial position of the workpiece;

 

The workpiece coordinate system of the machine tool is set incorrectly, or the zero point of the machine tool is reset in the processing process, resulting in changes. Most machine tool collisions occur during the rapid movement of the machine tool. At this time, the collision hazard is also the greatest, which should be avoided. Therefore, the operator should pay special attention to the initial stage of program execution and tool replacement of the machine tool. At this time, once the program is edited incorrectly and the diameter and length of the tool are input incorrectly, it is easy to collide. At the end of the program, if the sequence of the tool withdrawal action of the NC axis is wrong, the collision may also occur.

 

To avoid the above collision, the operator should give full play to the functions of the five senses when operating the machine tool. Observe whether the machine tool has abnormal action, sparks, noise, abnormal sound, vibration, and burning smell. If abnormal conditions are found, the program should be stopped immediately, and the machine tool can continue to work only after the problem of the standby machine is solved.

 

In short, mastering the operating skills of CNC machine tools is a step-by-step process, which cannot be achieved overnight. It is based on mastering the basic operation of machine tools, basic machining knowledge, and basic programming knowledge. The operating skills of CNC machine tools are not unchanging. It is an organic combination that requires operators to give full play to their imagination and practical ability. It is innovative labor.
