Abstract

The invention discloses a grinding liquid of tantalum and its alloy and making method in the precise mechanical polishing domain, which comprises the following parts: 25% even composition of grinding material and composite grease, 25% vegetable oil and 50% kerosene, wherein the bulk rate of grinding material and composite grease is 1: 1; the composite grease is composed of 45% stearic particle, 40% paraffin and 15% beeswax when the environmental temperature is over 20 deg. c or 40% stearic particle, 45% paraffin and 15% beeswax when the environmental temperature is below 20 deg. c. The preparing method of grinding liquid comprises the following steps: heating the allocated composite grease to fusion; filtering; adding the grinding material, vegetable oil and kerosene sequently and proportionally.

Description

technical field [0001] The invention relates to a special mixed grinding liquid for mechanical grinding, which is a special grinding liquid for precision mechanical grinding of metal tantalum and its alloys, and is also suitable for soft metals with similar grinding material properties. The abrasive liquid is suitable for industries such as aerospace manufacturing engineering and machinery manufacturing. Background technique [0002] In mechanical grinding and other grinding processes, grinding liquid and grinding paste are often used. Dry grinding uses abrasive paste, and wet grinding uses abrasive liquid. The role of the abrasive is to evenly distribute the abrasive on the surface of the grinding tool, so that the abrasive can cut the surface of the workpiece at the same time. At the same time, the grinding liquid also plays the role of lubrication, cooling and chemical film formation, so as to promote the smooth progress of grinding and improve the grinding effect. [...
