Why are there many precision CNC processing plants, but so many well-known companies choose VMT?

High machining precision and stable machining quality;

It can carry out multi-coordinate linkage, and can process precision CNC machining parts with complex shapes;

When the precision CNC machining parts are changed, generally only the CNC program needs to be changed, which can save production preparation time;

The machine tool itself has high precision and rigidity, and can choose favorable processing amount, and the productivity is high (generally 3 to 5 times that of ordinary machine tools);

The high degree of automation of machine tools can reduce labor intensity;

·Higher quality requirements for operators and higher technical requirements for maintenance personnel.

In the precision CNC processing plant, the machining center of the VMT precision CNC processing plant is mainly used for the processing of mold cores, inserts and other key mold parts and copper males. The quality of the mold core and insert directly determines the quality of the mold forming part. The quality of copper processing directly constrains the influence of EDM processing. For the assurance of CNC machining quality, the key lies in the preparation before CNC machining. As far as precision CNC machining plants are concerned, in addition to rich machining experience and mold knowledge, good communication should also be paid attention to during work, especially with the production team, Communication with colleagues.

VMT has a strict CNC machining process. In short, there are the following important steps:

1) Read drawings and program sheets

2) Transfer the corresponding program to the machine tool

3) Check the program header, cutting parameters, etc.

4) Determination of the machining size and allowance of the workpiece on the workpiece

5) Reasonable clamping of the workpiece

6) Precise alignment of the workpiece

7) Accurate establishment of workpiece coordinates

8) Selection of reasonable tools and cutting parameters

9) Reasonable clamping of tools

10) Safe trial cutting method

11) Observation of machining process

12) Adjustment of cutting parameters

13) Problems during processing and timely feedback from corresponding personnel

14) Inspection of workpiece quality after processing

VMT requires all staff to pay attention before CNC machining:

1) For the new mold, the CNC machining drawing should meet the requirements and the data should be clear; the CNC machining drawing of the new mold should have the signature of the supervisor, and each column of the data processing drawing has been filled in.

2) The workpiece has the qualified mark of the quality department.

3) After receiving the program sheet, check whether the reference position of the workpiece is consistent with the reference position of the drawing.

4) Look at each requirement on the program sheet, and confirm whether the program and the requirements of the drawing are consistent. If there is a problem, you must work with the programmer and the production team to solve the problem.

5) According to the material and size of the workpiece, judge the rationality of the programmer's selection of tools for roughing or light-knife programs.

If the tool application is found to be unreasonable, the programmer should be notified immediately to make corresponding changes in order to improve the CNC machining efficiency and the workpiece CNC machining accuracy.
