What are the processing requirements of precision parts processing technology?
1, parts to remove oxide skin, parts processing surface, there should be no scratches, scratches and other damage to the surface of the parts of the defect, remove burrs flash;
2, after tempering treatment, parts for high-frequency quenching, 350 ~ 370℃ tempering, HRC40 ~ 45, carburizing depth 0.3mm, high temperature aging treatment;
3, the unmarked shape tolerance should meet the requirements of GB1184-80, the allowable deviation of the unmarked length size is ±0.5mm, and the casting tolerance zone is symmetrical to the basic size configuration of the blank casting;
4. The fillet radius R5 is not noted, the chamfer is 2×45°, and the acute Angle is blunt;
5, the temperature shall not exceed 100℃, after the gear assembly, the tooth surface contact spots and backlash should meet the requirements of GB10095 and GB11365;
6, the assembly of the hydraulic system is allowed to use sealing filler or sealant, but should be prevented from entering the system, into the assembly of parts and components (including purchased parts, outsourced parts), must have the inspection department of the certificate can be assembled.
