Grinding process for flange surface

Abstract

The invention discloses a grinding process for a flange surface. The grinding process comprises the following steps: firstly, fixing a flange on a base of a cutting machine tool, adjusting a cutting head for cutting to a proper height, and then transversely and horizontally cutting a front side and a back side of the flange; secondly, performing water spraying treatment on the cut flange surface; thirdly, taking out the flange on which water is sprayed and grinding, stopping until dust appears on the flange, and repeating the second step and the third step according to conditions until grinding is qualified; and fourthly, cleaning the polished flange, and then performing drying treatment on the cleaned flange. According to the grinding process disclosed by the invention, the flange surface is cut by a cutting machine tool first, so that a large amount of grinding time can be saved; in addition, the cost for grinding an abrasion wheel is reduced; and besides, dust can be prevented from being generated during grinding, so that danger caused by production and operation is avoided, and hazards to health of an operator are eliminated.

Description

technical field [0001] The invention relates to a grinding process, in particular to a grinding process of a flange surface. Background technique [0002] Existing flanges are generally polished on the surface of the flange after forming to make it smooth and flat. However, the existing grinding methods generally generate a large amount of dust, but the dust will explode when it encounters a fire. It will pose a health threat to the operator, and long-term grinding will consume a large number of grinding wheels and increase costs, so there is an urgent need for a grinding method that can do dust-free grinding. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grinding process capable of reducing the generation of dust when grinding the flange surface, aiming at the deficiencies of the above-mentioned prior art. [0004] The technical solution adopted by the present invention is: a grinding process for the flange...
