Abstract
A belt grinding is integrated with an electroerosion machine for contouring the working surface of a mill roll and providing a texture thereon. The belt grinder can superfinish the roll and remove peaks in the surface without significantly affecting the mean surface roughness produced by the electroerosion.
Claims14
A method of treating a roll comprising the steps of:
- while supporting the roll in a surface-treatment machine,
- (a) subjecting the roll to an electroerosion process over an outer surface thereof by treating the outer surface of the roll with an electroerosion apparatus to impart a predetermined contour to said roll and form on the outer surface an outer texture having outwardly projecting peaks having outer tips;
- and
- (b) thereafter subjecting said outer surface to a fine machining process by treating the outer surface with a belt-grinding apparatus to eliminate only the outer tips of the peaks in the surface texture formed by the electroerosion process without changing the texture of the roll.

A machine for treating a roll comprising:
- a machine stand adapted to support the roll;
- an electroerosion unit for subjecting the roll while supported on the stand to an electroerosion process over an outer surface thereof to create on the outer surface of the roll a texture having outwardly projecting peaks with outer tips;
- and
- a belt grinding device integrated with said electroerosion unit for subjecting said outer surface while the roll is supported on the stand to a fine machining process to eliminate only the tips of the peaks in the surface texture formed by the electroerosion process without changing the texture imparted to the roll.
