Mechanical parts processing industry is the pillar of the national economy, with a very promising future. In the processing of precision mechanical parts, processing plant will have many requirements and regulations on the processing process to ensure the qualification rate of the factory parts. So we know the requirements of precision mechanical parts processing technology processing? Let's take a look below!
1, parts to remove oxidation, parts processing surface, there should be no scratches, scrapes and other defects that damage the surface of the parts, remove burrs flying edge;
2, by tempering, parts for high-frequency quenching, 350 ~ 370 ℃ tempering, HRC40 ~ 45, carburizing depth of 0.3mm, high-temperature aging treatment.
3, not injected shape tolerance should be consistent with the requirements of GB1184-80, not injected length size allowable deviation ± 0.5mm, casting tolerance zone symmetry in the basic size configuration of the blank casting;
4, not injected rounded radius R5, not injected chamfer are 2 × 45 °, acute angle inverted blunt;
5, the temperature shall not exceed 100 ℃, gear assembly, tooth surface contact spots and side clearance should comply with the provisions of GB10095 and GB11365;
6, assembly of the hydraulic system allows the use of sealing filler or sealant, but should be prevented from entering the system, into the assembly of parts and components (including outsourced parts, outsourced parts), all must have the inspection department's certificate of compliance before assembly.
