Share some operating skills of CNC lathe processing

1. Programming skills

Because the factory has high requirements on the precision of the processed products, the items to be considered when programming the CNC lathe include the processing sequence of the parts and the selection of a reasonable speed, feed and depth of cut according to the hardness of the material.

Second, the knife skills

Tool setting is divided into tool setting instrument tool setting and direct tool setting.

3. Debugging skills

After the parts are programmed, they need to be tested and debugged after the tool is set. In order to prevent errors in the program and mistakes in tool setting, resulting in collision accidents, we should first perform idle travel simulation processing and face them in the coordinate system of the machine tool. The tool is moved to the right by 2-3 times the total length of the part; then start the simulation processing, after the simulation processing is completed, confirm that the program and tool setting are correct, and then start processing the part. After the first part is processed, first self-check to confirm that it is qualified , and then find a full-time inspection and inspection. After the full-time inspection is confirmed, it means that the debugging is over.

Fourth, complete the processing of parts

After the first piece of trial cutting is completed, the parts will be mass-produced, but the qualification of the first piece does not mean that the whole batch of parts will be qualified, because during the processing, the tool will be worn due to the difference of the processing material, and the processing material Soft, the tool wear is small, the processing material is hard, the tool wear is fast, so in the process of processing, it is necessary to check frequently, increase and decrease the tool compensation value in time to ensure the qualified parts.

5. Prevent the machine tool from colliding

Machine tool collision is a great damage to the accuracy of the machine tool, and it has different effects on different types of machine tools. Generally speaking, it has a greater impact on the machine tool with low 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.
