Miniature bearing lapping technology optimization

Miniature bearing ultra lapping technology optimization of miniature bearing ring final machining process for the super lapping. Optimization of grinding process is the basis of super research process, to use different ultra lapping process of bearing inner ring raceway tested various surface analysis: if there is optimization of the grinding surface layer, then choose a good super lapping process, can make the miniature bearing wear resistance increase greatly. The miniature bearing isotope trace wear test showed that selects the optimization of lapping process of bearing, its wear resistance is not worse than the similar bearing. Ultra lapping optimization process include: (1) the metal removal rate is high, the shorter time to remove the grinding surface metamorphic layer; (2) the surface roughness up to standards, processing shape R and waviness improve requirements; (3) process (low cost Abrasive wear is small, less rework, short time) ； (4) formed by ultra lapping surface microhardness and residual stress distribution, the rupture is better; (5) the ultra lapping processing dynamic stability ( High precision processing good retention, shape) 。 Different surface quality of ultra lapping process leads to the channel of difference; Miniature bearing inner ring is one of the main parts of bearing, improve surface quality of the inner ring is the main way to lengthen the service life of bearing.
