Compares with the general machine parts, the bearing components were short and the thin rotation surface body, the solid of revolution had decided processed the engine bed quite to be unitary, overwhelming majority for lathe and grinder; Short and had decided thinly its axial rigidity is good, the lateral deformation may ignore, the radial direction rigidity is bad, time the processing step-up method must have the special consideration.
Although the rolling bearing components the structure is simple, but the specification is very high, thus has the following several processing characteristic:
1st, precise processing
The bearing components major part surface must pass through the abrasive machining, rubs the finishing size and the GDOP all take μM as the unit, specially the ferrule roller conveyer and the rolling body precision is higher, needs the superfinishing or the attrition processing.
2nd, multi-working procedure processing
The bearing components request high, the production working procedure are inevitably many.The common bearing lives the production and demand 20~40 working procedures, many reaches 70 multi-channel.
3rd, formation processing
The bearing components active face all rotates the formation surface, suits in uses the formation law processing.If the ferrule roller conveyer forging rolling and the vehicle rub, all is uses the formation cutting tool or guards against the board processing.
Moreover, the overwhelming majority bearing all is the standardized product, the identical model bearing required quantity is very big, in order to enhance the productive forces, reduces the cost, the guarantee quality and widely uses the new technology, the enhancement mechanization and the automated level, the bearing company is generally carries on the mass production according to the bearing model and the variety, even may establish special carries on the production from the generatrix or the assembly line.
