?How to improve the quality of CNC machining workpiece?

1, reasonable use of CNC machining tools

Processing steel, copper, the smooth knife to strictly distinguish the use of the knife, the balance of the smooth knife to be reasonable, so that the smoothness of the workpiece and the service life of the tool will be better.

2. Before CNC machining, check whether the tool is swinging within the allowable tolerance range with the calibration table. The tool head and lock nozzle should be blown clean with the air gun or wiped with a cloth before installing the tool.

3. When loading and clamping, pay attention to see whether the name and model of CNC workpiece and program sheet are the same, whether the material size is matched, whether the clamping height is high enough, with calipers.

4, CNC machining program list to the mold by reference Angle in the same direction, then check for the 3 d map, especially the artifacts have been drilling for water, be sure to see 3 d figure are consistent with the water on the workpiece, such as an unidentified to timely feedback under the master programmer or find fitter for 2 d drawings, 2 d and 3 d reference Angle.

5, CNC machining program list to regularization, including mold number, name, program, content, tool size and feed processing capacity, especially the tool clamping length of security, reserved allowance of each program, laser scalpel, please indicate clearly, R surface and plane to meet suitable place, indicate the program in the list, the operator should increased by 0.02 ~ 0.05 MM when processing processing first, gong a few stopped to see if meet shun dao, touch the up level, if not fall gong again.

6. Before processing, it is necessary to understand the content of the program sheet of CNC machining. The program sheet must have 2D or 3D pictures and mark the six-sided data of "X length, Y width and Z height".

All the plane should be marked with "Z" value, the operator is convenient to detect whether the data is correct after processing, the tolerance should be marked with tolerance data.

7, the machine tool processing speed operator to strictly control, F speed and S spindle speed should be reasonable to adjust each other, F speed faster relative to the S spindle to speed up, in different regions have to adjust the speed.After processing, check the quality of the rear can be off, to do a perfect processing.
