Method for grinding disc scissors

Abstract

A method for grinding disc scissors belongs to the metallurgical machinery maintenance field. The method is characterized by including the steps that on a grinding machine, a 80# grinding wheel is used for roughly grinding the disc scissors for 1 hour, and a 150# grinding wheel is used for accurately grinding and polishing the disc scissors until the roughness of the disc scissors is 0.1 micrometer. By the adoption of the method for grinding the disc scissor, the grinding accuracy of the disc scissors can be improved, slitting and trimming can be normally conducted when a pair of scissors is longitudinally cut, and quality of strip steel products is improved.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery maintenance, and in particular relates to a grinding method of disc scissors. Background technique [0002] When the disc scissors are used for slitting and matching knives, it is easy to cause burrs on the slitting and curling edges, resulting in a decline in product quality. Contents of the invention [0003] In order to improve product quality and ensure normal slitting and trimming when slitting and matching knives, the invention provides a grinding method for disc scissors. [0004] Technical scheme of the present invention is: [0005] 1. The grinder uses 80# grinding wheel to roughly grind the disc scissors for 1 hour; [0006] 2. Use 150# grinding wheel to finely grind and polish the disc scissors to a roughness of 0.1um. [0007] The invention can improve the grinding precision of the disc scissors, ensure normal slitting and trimming when the slitting knife is equipped, and...
