In general, mold parts processors use the following methods:

1, washing processing: mainly milling cutter for the plane milling plus

Grinding: Grinding the surface of the workpiece with grinding wheel

3, planing processing: The main use of planer to the surface of the workpiece planing.

4, special processing: is the direct use of electrical energy, chemical energy, etc. for processing methods.

5, CNC machining: mainly through digital information to control the machine tools, so that the processed parts and knives to produce the required relative motion, from the surface to realize the processing of parts.

The mold parts processing process generally adopts the following methods:

1, geometric shape accuracy The geometric shape accuracy of the shaft neck should generally be limited to the diameter metric range. When the precision of geometric shape is required to be high, the tolerance allowed by it may be specified separately on the part diagram.

2, surface roughness depending on the surface of the part, may have different surface roughness values, for example, the surface roughness of the spindle support shaft neck of an ordinary machine tool is Ra0.160.63 um, and the surface roughness of the shaft neck is Ra 0.632.5 um, With the increase of machine running speed and precision, the surface roughness requirement of shaft parts will become smaller and smaller.

3, dimensional precision shaft neck is the main surface of shaft parts, it affects the shaft rotation accuracy and working state. The straight diameter accuracy of the shaft neck is usually IT69 according to its use requirements, and the precision shaft neck can reach IT5.

4, the position accuracy mainly refers to the coaxial degree of the matching shaft neck of the assembly transmission part relative to the supporting shaft neck of the assembly bearing, which is usually expressed by the matching shaft neck beating the radial circle of the supporting shaft neck; According to the use requirements, the high precision axis is 0.0010.005 mm, while the general accuracy axis is 0.010.03 mm. In addition, there are the coaxial degree of the inner and outer cylindrical surfaces and the vertical degree requirements of the axial positioning end surfaces and axial lines.
