various kinds of imported bearing main parts process:

1. The collar processing: bearing inner ring and outer ring in the processing of raw materials or blank form of different and different, including car before processing process can be divided into the following three, the whole process : great material or tube material (some good material must be approved by forging and annealing, fire)-car processing-heat treatment--  grinding and polishing -final inspection incoming- -rust (for set of assembly)

2. The machining process of the steel, steel ball processing of raw materials in the same condition is different and different, including cutting or before the ball of light strikes the process, can be divided into the following three, before heat treatment process, and can be divided into the following two kinds, the whole process for: great material or wire cold blunt (some good material cold rushed to blunt band and after annealing)--amid the cut, coarse grinding, RuanMo or light, heat treatment-hard ball mill-fine grinding-let or grinding-final inspection group-rust, packaging, storage < stay close set of assembly >.

3. Roller of machining process of the roller in the raw materials processing different and different, including heat treatment process can be divided into the following before two kinds, the whole process for: great processing or wire furnaces of cold upsetting string band and RuanMo-after heat treatment-string of soft spots-coarse grinding outer diameter of the coarse grinding end-eventually-grinding end-fine grinding end outer diameter, grinding-final inspection group-rust, packaging, storage (to set of assembly).

4. Keep aircraft processing process keep aircraft processing process according to the structure design and the raw materials of different, can be classified into the following two categories:

(1), shear and sheet metal cutting, stamping, plastic and finishing, pickling or the shot peening or string of light-final inspection, rust and packaging, storage (stay close set of assembly)

(2) the entity kept the aircraft processing process: the entity kept the aircraft processing, in raw materials or hair bad different and different, including processing can be divided into the following car before four blank type, the whole process for: great materials, pipe materials, forging, castings, car inner diameter and outer diameter and face, chamfering--drilling (or pull holes, boring)- -antirust pickling final inspection, packaging, storage < stay close set of assembly >.
