CNC machining refers to a mechanical processing method that processes parts on a CNC machine tool and uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts varieties, small batches, complex shapes, high accuracy, and achieve efficient and automated processing.
Generally speaking, the process procedures for CNC machine tool processing are consistent with those for traditional machine tool processing. However, since CNC is a one-time clamping process that continuously and automatically processes all turning processes, it is necessary to pay attention to some matters after completing CNC machine tool processing.
Precautions after processing:
1. Remove chips, wipe the machine tool, and keep the machine tool and environment clean when using it.
2. Pay attention to checking or replacing the oil wiping plate on the worn out machine tool guide rail.
3. Check the status of lubricating oil and coolant, and add or replace them in a timely manner.
4. Turn off the power supply and the main power supply on the machine tool operation panel in turn.
5. When starting the machine tool, the principles of first returning to zero (except for special requirements), manual, inching, and automatic operation should be followed. The operation of the machine tool should follow the principle of first low speed, medium speed, and then high speed. The operation time of low speed and medium speed should not be less than 2-3 minutes. After confirming that there are no abnormalities, work can be started.
6. It is strictly prohibited to strike, correct, and correct the workpiece on the chuck or between the centers. The next step of work can only be carried out after confirming the workpiece and the cutter.
7. The operator must stop the machine when changing tools, workpieces, adjusting workpieces, or leaving the machine tool during work.
8. Operators are not allowed to disassemble and move the safety and protective devices on the machine tool arbitrarily.
9. Before the machine tool starts processing, it is necessary to use a program verification method to check whether the program used is similar to the part being processed. After confirming that there is no error, the safety shield can be properly secured and the machine tool can be started to process the part.
10. Machine tool accessories, measuring tools, and cutting tools should be properly stored and kept intact and in good condition. If they are lost or damaged, they should be compensated.
11. After the training, clean the machine tool, keep it clean, move the tailstock and carriage to the end of the bed, and cut off the power supply of the machine tool.
12. In case of any malfunction or abnormal phenomenon during the operation of the machine tool, it is necessary to immediately shut down the machine, protect the site, and immediately report to the site responsible.
13. Operators are strictly prohibited from modifying machine tool parameters. If necessary, the device administrator must be notified and requested to modify it.
14. Understand the technical requirements of the part drawing, and check the size and shape of the blank for defects. Choose a reasonable method of installing parts.
15. Correctly select CNC turning tools, and ensure accurate and firm installation of parts and tools.
16. Understand and master the control and operation panel of CNC machine tools and their operating essentials, accurately input the program into the system, simulate inspection and room cutting, and make various preparations before processing.
17. If the lathe is found to have abnormal sound or malfunction during processing, it is necessary to immediately stop the machine for inspection and report to the instructor to avoid danger.
