Multi-abrasive particle abrasive belt

Abstract

The invention discloses a multi-abrasive particle abrasive belt. The multi-abrasive particle abrasive belt comprises a substrate, a bonding layer, a material grinding layer and a net type strengthening layer, wherein the substrate is of a continuous plane; the net type strengthening layer is fixedly arranged on the substrate and is located between the substrate and the bonding layer; the material grinding layer comprises a coarse abrasive particle layer, a middle abrasive particle layer and a fine abrasive particle layer, and the coarse abrasive particle layer, the middle abrasive particle layer and the fine abrasive particle layer are arranged on the bonding layer in parallel along the length direction of the multi-abrasive particle abrasive belt. The multi-abrasive particle abrasive belt disclosed by the invention has the advantages that the multi-abrasive particle abrasive belt is not easy to be destroyed, and the processing efficiency is increased.

Description

technical field [0001] The invention relates to a multi-abrasive abrasive belt. Background technique [0002] Grinding tools used in existing grinding machines are usually two types of grinding wheels and abrasive belts. Grinding wheels are the most used and widely used abrasive tools. When used, they rotate at high speed and can grind the outer circle and inner Coarse grinding, semi-finishing and fine grinding as well as grooving and cutting of circles, planes and various types of surfaces. The abrasive belt is a coated abrasive, called a flexible abrasive. The advantages of flexibility and safety, higher precision, and low grinding cost. In the existing technology, the grinding wheel has high speed, high dynamic balance requirements, poor safety, small single processing area, low abrasive belt strength, and is not suitable for high-speed operation. . In addition, some workpieces require rough grinding, medium grinding, and fine grinding during grinding, often requiring m...
