Technical Field

The invention relates to the field of chemistry, in particular to organic chemistry, and particularly relates to grinding oil for metal processing, and specifically relates to grinding oil for metal processing and a preparation method thereof.

Background

Grinding utilizes abrasive particles coated or pressed on a grinding tool to perform finishing processing (such as cutting processing) on a processing surface through relative movement of the grinding tool and a workpiece under a certain pressure. The grinding can be used for processing various metals, and the processed surface has the shapes of planes, inner and outer cylindrical surfaces, conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other molded surfaces. The processing precision can reach IT 5-IT 01, the surface roughness can reach Ra0.63-0.01 micron, and the grinding is generally carried out on the basis of fine grinding or finish turning. The manual grinding of the excircle can be carried out on a lathe, the grinding agent and the grinding oil are coated between the workpiece and the grinding tool, the workpiece is driven to rotate by a lathe spindle, and the grinding tool is supported by hands to carry out axial reciprocating movement.

In recent years, with the increase in size of industrial equipment and the trend toward high-load, high-temperature, and high-pressure operations, higher demands have been made on the performance of grinding oils for metal working.

Disclosure of Invention
