CNC machining refers to a machining method that processes parts on CNC machine tools and uses digital information to control the movement of parts and tools. It is a method for solving the problems of variable varieties of parts, small batches, complex shapes and high precision. , and to achieve high efficiency and effective automation.
The processing procedures of CNC machine tools and traditional machine tool processing are generally the same. However, because CNC is one-time clamping and continuous automatic processing to complete all turning processes, there are some things that need to be paid attention to after processing. The CNC machine tool processing is completed.
Points to note after treatment:
1. Remove the chips, wipe the machine tool, and keep the machine tool and the environment clean.
2. Pay attention to check or replace the wiper plate on the worn guide rail of the machine tool.
3. Check the condition of lubricating oil and coolant, and add or replace them in time.
4. Turn off the power supply and the main power supply successively on the machine tool control panel.
5. When starting the machine tool, the principles of return to zero first (unless special requirements), manual, gradual and automatic should be followed. The operation of the machine tool should follow the principle of low speed, medium speed and then high speed. The running time of low speed and medium speed should not be less than 2-3 minutes. Only when it is determined that there are no anomalies can work begin.
6. It is strictly prohibited to strike, straighten or correct the workpiece on the chuck or between the centers. The part and tool must be confirmed as tight before proceeding to the next step.
7. The operator must stop the machine when changing tools, parts, adjusting parts or leaving the machine tool.
8. Operators are not allowed to dismantle or move the safety insurance and protection devices of the machine tool at will.
9. Before the machine tool starts processing, the program verification method should be used to check whether the program used is similar to the parts to be processed. After confirmation, the protection device can be closed and the machine tool can start processing. parts.
10. Machine tool accessories, measuring tools and cutting tools should be properly stored and kept intact and in good condition. No compensation will be required in the event of loss or damage.
11. After training, the machine tool should be cleaned and kept clean, the tailstock and carriage should be moved to the end of the bed, and the machine tool should be cut.
12. When a machine tool malfunctions or an abnormality occurs during work, it should be stopped immediately to protect the site and immediately reported to the responsible person on site.
13. Operators are strictly prohibited from changing machine tool parameters. If necessary, the device administrator should be notified and asked to change it.
14. Understand the technical requirements of the part drawing and check whether there are any defects in the size and shape of the blank. Choose a reasonable method of installing parts.
15. Select CNC turning tools correctly and install parts and tools accurately and firmly.
16. Understand and master the control and operation panel of the CNC machine tool and its essential operating elements, accurately enter the program into the system, simulate the inspection and cutting of the chamber, and carry out various preparations before the treatment.
17. If you find that the lathe makes abnormal noise or malfunction during processing, you should immediately stop the machine for inspection and report to the instructor to avoid danger.
