Nanometer grinding process and nanometer grinding liquid

Abstract

The invention belongs to a machining method and a material, in particular to a nanometer grinding process and nanometer grinding liquid. In the nanometer grinding process, the nanoscale particles of solid matter are added into the grinding process; the nanometer grinding liquid is formed by mixing the nanoscale particles of solid matter and fluidic grinding liquid. The invention has the following beneficial effect: compared with the existing water-base or oil-base grinding liquid, the nanometer grinding liquid has greatly lowered indexes, such as grinding zone temperature, surface roughness, grinding resistance, grinding tool loss and the like; machining quality and economic benefit are obviously improved, and thus the invention has higher application value and market prospect.

Description

technical field [0001] The invention belongs to a mechanical processing method and material, namely a nano-grinding process and a nano-grinding fluid. Background technique [0002] Grinding is an important precision machining method, which is mainly used to improve the surface accuracy and surface integrity of the workpiece. However, the thickness of the chip layer in the grinding process is relatively thin, and the difference is tens to hundreds of times compared with cutting. Such a small cutting thickness will make the specific cutting force very large, the specific energy is very high, and a large amount of heat is generated, of which about 60%-95% of the heat is transferred to the workpiece, and less than 10% of the heat is carried away by the chips. The heat introduced into the workpiece is often too late to be introduced into the depth of the workpiece during the grinding process, and it gathers on the surface layer of the workpiece to form a local high temperature. ...
