In the mold factory, CNC vertical lathe, milling machine, CNC special machine CNC machining center is mainly used for mold core, inserts and other key parts of the mold and copper and other processing. The quality of the mold core and inserts directly determines the quality of the mold forming part. The quality of copper machining directly restricts the impact of EDM machining. For the assurance of CNC machining quality, the key lies in the preparation before processing, as far as this position is concerned, in addition to having rich processing experience and mold knowledge, we should also pay attention to good communication in the work, especially with the production team, colleagues.
The process of CNC machining
1) Read the drawings and program sheets
2) Transfer the corresponding program to the machine
3) Check the program head, cutting parameters, etc
4) Determination of the processing size and allowance of the workpiece on the CNC vertical lathe, milling machine, CNC special machine
5) Reasonable clamping of the workpiece
6) Precise alignment of the workpiece
7) Accurate establishment of workpiece coordinates
8) Reasonable selection of tools and cutting parameters
9) Reasonable clamping of tools
10) Safe test cutting method
11) Observation of the processing process
12) Adjustment of cutting parameters
13) CNC vertical lathe, milling machine, CNC special machine processing process problems and timely feedback of the corresponding personnel
14) Inspection of the quality of the workpiece after processing
Precautions before processing
1) CNC vertical lathe, milling machine, CNC special machine for the new mold, the processing drawing should meet the requirements, and the data is clear; the processing drawing of the new mold should have the signature of the supervisor, and the columns of the processing drawing have been filled.
2) The workpiece has the qualified mark of the quality department.
3) After receiving the program order, check whether the workpiece datum is consistent with the drawing datum.
4) Look at each requirement on the program sheet, confirm whether the requirements of the program and the drawings are consistent, if there is a problem, you must solve the problem with the programmer and the production team.
5) According to the material and size of the workpiece, judge the rationality of the programmer's rough or light tool program, if the tool application is found to be unreasonable, the programmer should be notified immediately to make corresponding changes, so as to improve the processing efficiency and the accuracy of the workpiece.
