Technical Processing Requirements for Precision Parts Processing


Machinery parts processing industry is the pillar industry of the national economy, with a very considerable prospect. When processing precision mechanical parts, the processing plant will have many requirements and regulations on the processing technology to ensure the qualified rate of the ex-factory parts. So do you know the requirements of processing technology for precision mechanical parts? Let's take a look at it together.

1. Remove the oxide skin of the parts. There should be no scratches, scratches and other defects on the surface of the parts. Remove burr flash.

2. After quenching and tempering, the parts are quenched at high frequency, tempered at 350-370 C, HRC 40-45 and carburized at a depth of 0.3 mm, and aged at high temperature.

3. The shape tolerance without injection should meet the requirement of GB1184-80. The allowable deviation of the length and dimension without injection should be (+0.5mm). The tolerance zone of the casting should be symmetrical to the basic dimension configuration of the blank casting.

4. No fillet radius R5, no fillet chamfers are 2 x 45 degrees, acute fillet chamfers are blunt;

5. Temperature shall not exceed 100 C. After gear assembly, the contact spot and backlash of the tooth surface shall conform to the requirements of GB10095 and GB11365.

6. Sealing fillers or sealants are allowed to be used when assembling hydraulic systems, but they should be prevented from entering the system. The parts and components (including outsourced parts and outsourced parts) that are assembled must have the qualification certificate of the inspection department before they can be assembled.
