Cutting Tool Applications Chapter 16: Grinding Wheels and ...

Grinding, or abrasive machining, is the process of removing metal in the form of minute chips by the action of irregularly shaped abrasive particles. These particles may be in bonded wheels, coated belts, or simply loose. Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material.

Non-circular grinding of backup rolls to reduce rolling ...

A non-circular shape was ground on the rolls. The empirical research took place at a hot strip mill. As a result, the 3D ground non-circular geometry of the backup rolls considerably reduced the rolling force variation. Key words: non-circular grinding, rolling mill, backup roll, rolling force variation.
