Description
Technical field
The present invention relates to a kind of preparation method of support of bearing more particularly to a kind of preparation sides of the high-intensitive support of bearing
Method.
Background technique
The support of bearing is automobile parts, and conventional preparation method is unable to satisfy the rigidity of product, is existed in use
Certain safe mass.
Chinese patent 201310707768.8 discloses a kind of support of bearing milling both ends of the surface technique of automobile middle shaft, special
Sign is, mainly consists of the following steps: (1) firstly, choosing workpiece material HT200, roughness is 12 μm, and lathe is the milling of YG6 formula
Bed, cutter X52K slotting cutter=100mm, z=10；Cutting fluid is common emulsion；(2) cutting data then, is selected, determines milling
Depth is cut, determines feed engagement；(3) milling cutter pure ground standard and cutter life are selected, and milling cutter tooth knife face greatest wear amount is thick
2.0 when processing, 0.5 when finishing, actual cut speed and feed engagement are 0.125mm/z, cutting speed V=94.2m/
Min, amount of feeding 0.125mm/z；(4) lathe requirement: selected cutting data 375mm/min when skiver, is symmetrically installed
Milling cutter.This technique is some processing step for the support of bearing, this processing step is relative complex, and manufacturing cost is relatively high,
Properties of product are not relatively strong.
