I. processing of bearing rings
1, forging processing forging processing is
the primary processing of bearing ring processing, also known as blank
2. The main effect of annealing ring
annealing is to obtain the microstructure of fine, small, even and round
carbide particles evenly distributed on the ferrite matrix, so as to prepare
the microstructure for subsequent cold processing and final quenching and
3.turning processing turning processing is
the semi-finished processing of bearing ring, can also be said to be forming
4.Heat treatment heat treatment is the key
processing procedure to improve the internal quality of bearing
5.Grinding processing grinding processing is
the final processing of bearing ring and roller processing, known as finished
II. Processing method of bearing ball
1. Blank making: various ball blanks are
made by various technological methods.
2. Rough grinding: put the ball blank into
two concentric rings with the same size of upper and lower grinding disks with
triangular grooves, which are matched with the size of the blank, and add
grinding oil and coarse abrasive. The upper grinding disc rotates and the lower
grinding disc does not move.
3. Cleaning: clean the grinding oil and
coarse abrasive residues stuck on the surface of the ball after each rough
4. Fine grinding: put the roughened blank
into the fine grinding machine, add ultra-fine grinding oil with low viscosity
and fine abrasive to grind to the standard size;
5. Polishing: the process is similar to
rough grinding and fine grinding.
Bearing assembly is the last step in
bearing production, which has important influence on bearing performance.
According to different technical requirements, the parts processed by various
processes are assembled into various precision, various clearance and other
special requirements of bearing products.
