2. The processing of steel balls, steel balls processing same in accordance with the state of raw materials may differ, which

Cut or process in frustration before the photosphere, can be divided into the following three, before the heat treatment process can be divided into the following

Two kinds, the whole process are: bar or wire cold punch (needed some punch after punch cold bar

Belts and annealing) ---- setback cut, coarse grinding, Polishing heat or light ball ---- ---- ---- grinding hard grinding -

--- Lapping or polishing ---- ---- antirust final inspection grouping, packaging ---- storage (to be co-suit distribution);

3. Roller roller machining process depending on the raw materials vary, of which the first heat treatment

The process can be divided into the following two, the whole process are: bar lathe or wire rod for cold heading after string ring

---- ---- Roughing end surface with an outer diameter of coarse grinding and heat treatment Polishing ---- ---- ---- series end mill end soft spots

---- ---- Finely ground surface finish grinding outer diameter OD - --- ---- final inspection packet antirust, packaging ---- warehousing (

To be co-suit distribution);

4. Cage holding the process according to the process frame structure and materials of different design, can

Divided into the following categories:

(1) sheet → shear → punching → stamping → shaping and finishing → pickling or shot blasting or string light

→ final inspection → antirust, packaging → storage (to be co-suit distribution);

Process (2) solid cage: the entity holding the processing holder, according to different raw materials or bad hair

Vary, of which the first vehicle processing can be divided into the following four types of rough, the whole process are: bar

Materials, pipe materials, forgings, castings ---- car diameter, outside diameter, face, chamfer ---- Drilling (or broaching,
