Manufacturing process of superfine grinding roller

Abstract

The invention relates to a manufacturing process of a grinding roller, in particular to a manufacturing process of a superfine grinding roller, which includes the following steps: firstly a blank roller is processed according to roller graphical dimensions, then fine processing is performed on the blank roller, polishing processing is performed on the surface of a roller body after the fine processing is performed on the roller body, partial repair is performed on the surface of the roller body with air holes or pinholes, chromium plating, fine grinding and polishing are performed on the surface of the roller body, the roller surface is rolled repeatedly in reciprocating mode by using a rubber wheel containing sand to be molded, a certain number of superfine grinding rollers are molded through grinding, finally detection about roughness and gloss is performed on the roller surfaces of the manufactured superfine grinding rollers according to requirements to form quality inspection results. The manufacturing process of the superfine grinding roller changes a traditional manufacturing process of a grinding roller completely, the superfine grinding roller manufactured by the process is good in accuracy, long in service life and consistent in roughness, gloss and uniformity, and the superfine grinding roller cannot be manufactured by an original manufacturing process.

Description

technical field [0001] The invention relates to a manufacturing process of a grinding roller, in particular to a manufacturing process of an ultrafine grinding roller. Background technique [0002] Ultra-fine abrasive rollers are mainly used for surface treatment of PVC calendered film, PE, PP, and PET cast film, requiring very fine sand grains on the surface, generally between 600 mesh and 1200 mesh. The traditional process of making ultra-fine grinding rollers is to grind the surface of the rollers and then sandblasting and electroplating on the surface. However, this process has a fatal shortcoming that the sandblasting is uneven. , a large amount of dust will be formed and scattered in the air, and it is impossible to form the surface of the roller into a frosted pattern, let alone meet the product quality requirements. At present, domestic enterprises that use ultra-fine abrasive rollers are importing them from European and American countries one after another, and the...
