Abrasive Grinding Defects. Hazards Related to Abrasive

The work piece is more affected by the heat mainly because it retains a larger proportion of the heat generated during the grinding operation. The work piece can get damaged in various ways including some or all of the following. There could be certain reactions which take place at the hightemperatures attained during grinding.

Analysis of a HighPrecision Grinding Machine WARSE

Heat sources in grinding machine There are several heat sources in the grinding machine: a linear motor for x and y axis feeding, a ball screw for zaxis motion, a rotary motor for c axis rotation, and linear guides. Heat generation from x and y linear guides of 18m/min maximum speed is about 1.9W. Since z axis speed is 3m/min,
