Bearing the superfinishing process stage

Bearing as the main parts of all kinds of mechanical operation, in order to make quality of bearing for better performance in terms of use, bearing used in the process of machining the superfinishing technology, precision processing technology refers to the machining precision and the surface is bright and clean degree is higher than the corresponding method of finishing of all kinds of processing technology. Its main divided into four stages.     The bearing network analysis bearing superfinishing process of four stages: & emsp;   ( 1) Strong cutting phase. Workpiece surface roughness peaks and sharpening stone surface contact, the contact stress is large, the grinding grain broken broken self-sharpening, cutting effect.     ( 2) Normal cutting phase. Workpiece roughness layer be ground in addition to, or enter the normal cutting stage, oil stone surface has no black chip attached but continued cutting.     ( 3) Grinding the transitional phase. Grain to decrease since less, grinding grain blade edge is smooth, embedded chip oxide start sharpening stone gap, abrasive powder blocking oil stone hole, can only make the grits weak cutting, accompanied by squeezing and light effect, workpiece surface roughness quickly cut at this moment, a black chip oxide attached oil stone surface.     ( 4) Stop cutting grinding stage. Friction between oil stone and workpiece is smooth, greatly increase the contact area and pressure drop, grits can not wear out the oil film in contact with the workpiece, when on the surface of the bearing oil film pressure and oil-stone phase equilibrium, oil stone was floating up. In the oil film formation, then have no cutting action. This stage of superfinishing. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
