Description

Technical Field

[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing.

[0003] In the process of mechanical processing, grinding and deburring are very important after the workpiece is processed. The burrs in the product installation process lead to the unsmooth structure and jamming, which is particularly critical on automatic equipment. Some electrical equipment causes short circuits in the circuit due to the falling of burrs during work, damaging the equipment. The friction between the accessories is severe due to the burrs or falling on the surface, which greatly reduces the working time. If the burrs fall into the hydraulic or pneumatic system circuit, the circuit will be blocked and the equipment cannot operate, resulting in losses. In the aerospace industry, some temperature electromagnetic relay equipment causes electromagnetic structure jamming due to the falling of burrs, which has serious consequences. The burrs on some shaft workpieces can cause serious damage to the sealing ring gasket and damage to the sealing, causing failures. The mechanical and electrical product accessories are not smoothed before electroplating, which has an adverse effect on the adsorption of the electroplating layer. The burrs may cause harm to the human body. In fact, deburring is to remove the thorns or flash formed at the intersection of the part surface and the surface. The harmfulness of burrs is particularly obvious, which has gradually attracted widespread attention, and people have begun to study the generation mechanism and removal methods of burrs.
