However for creep-feed grinding with slow workspeeds and large depths of cut, the energy partition is only about 5%. Such low energy partitions are attributed to cooling by the fluid at the grinding zone. Heat conduction to the grains can also reduce the energy partition especially with CBN abrasives which have high thermal conductivity.The maximum average temperature of grinding media up to 295.057 K appears at the grinding media filling 25% and the number of lifters 12.

Probing the effect of grinding-heat on material removal mechanism
The heat generated during the grinding process has a direct impact on the removal behavior of the rail material and the surface quality. Excessive grinding heat will not only speed up the abrasive abrasion blunt, but also affect the metallographic structure of the rail [14,26]. The heat generated during the grinding process would cause defectsLab mills are essential lab units used for sample preparation and chemical and physical analyses. By reducing the particle size of materials, mills can help researchers homogenize samples and achieve consistency and accuracy in testing.
