TIMKEN bearing grinding process, the workpiece surface layer will be grinding wheel cutting force, the role of compression and friction. Especially for the latter role, the workpiece surface layer formed directional strong plastic deformation and hardening layers. The metamorphic layers are also necessarily affect the change of residual stress in surface layer.
(1) cold plastic deformation in the TIMKEN bearing grinding process, each grain is equivalent to a blade but in many cases (especially after wear of wear particles), the cutting edge of the front corner is negative, except for cutting role of wear particles, is to make the surface subjected to compression (plough), clear plastic deformation of workpiece surface layer. This deformation degree of deformation layer with the degree of grinding blunt grinding feed and grow larger.
(2) hot plastic deformation (or high temperature plastic deformation) grinding heat transient high temperature of TIMKEN bearings are formed on the surface of the workpiece, the workpiece surface layer of sharp decline in some depth the elastic limit, or even the extent of the loss of elasticity. Workpiece surface layer on grinding force at this time, especially under the effect of compression and friction, causing elongation of freedom, subject to limitations as base metal, the surface is compressed (plough), in surface layer caused by plastic deformation. High temperature plastic deformation in grinding process of the same cases, increased with the rise in surface temperature.
