Super lapping processing method from 30 s began to grow, which is founded in bearing rolling surface processing, it is a kind of precision, economic processing technology, along with the machining parts precision and surfac e quality asks is ceaseless rise, super lapping processing get more and more extensive application. In our bearing manufacturing light the whole processing (polishing, emery cloth belt grinding, ultra precision grinding and super lapping) occupies an important position.bearing manufacturer
Super lapping processing, referred to as "super finishing", generally refers to the good lubrication condition, processed workpiece according to a certain speed rotation, stone according to certain pressure elastic pressure machining on the surface, and in the perpendicular to the direction of rotation according to certain rules for reciprocating oscillatory motion of a kind of automatically through light the whole processing method.
Super lapping working the whole process including independent distinguish obvious three stages: dressing, constant cutting, polishing (also has divided into: cutting sta ge or self-sharpening stage, half cutting stage, light the whole stage). And the whole process in the basic technological parameters (such as cutting speed, oilstone pressure and hardness, oscillation frequency, abrasive type, workpiece materials and lubrication coolant, etc.) the condition of constant is automatic.
Super lapping processing advantages
1. Can effectively reduce circular deviation (mainly waveness).
2. Can effectively improve the raceway bus of linearity or processed into required shape crown.double bearing
3. Can purify grinding metamorphic layer, to reduce the surface roughness value.
4. Can make the surface has the residual compressive stress.
5. Can in the processing surface formation texture uniform fine, ideal cross lines.big ball bearing
6. Can make work contact bearing area increases.
