Abrasive band

Abstract

The invention discloses an abrasive band, which comprises a base body, a bonding layer and an abrasive material layer, wherein the abrasive material layer consists of a bottom material and an abrasive material arranged on the bottom material; the base body is fixed with the bottom material of the abrasive material layer through the bonding layer; the width of one end, supporting the bonding layer, of the base body is smaller than the width of the other end of the base body; the two side surfaces of the base body are inclined surfaces or arc-shaped surfaces; the bonding layer covers the base body; after the abrasive material layer covers the bonding layer, the two side surfaces of the bonding layer and the abrasive material layer are identical to the side surface of the base body; grooves are formed in the base body; the abrasive band also comprises a reticular reinforcing layer; the reticular reinforcing layer is embedded into the grooves formed in the base body; after the reticular reinforcing layer is fixed on the base body, the reticular reinforcing layer is positioned between the base body and the bonding layer. The abrasive band has the characteristics that workpieces cannot be easily damaged; the self service life is long.

Description

technical field [0001] The invention relates to an 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 rotates at a high speed. When the bottom edge of the workpiece just contacts the edge of the abrasive belt, a high impact force will be generated, which will easily make the edge of the abrasive belt The diamond layer of the abrasive belt is damaged, and after working for a period of time, the edge of the ...

[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 rotates at a high speed. When the bottom edge of the workpiece just contacts the edge of the abrasive belt, a high impact force will be generated, which will easily make the edge of the abrasive belt The diamond layer is damaged, and after working for a period of time, the edge of the abrasive belt is easy to wear, crack, peel off or even fall off

And it will cause damage to the workpiece

In the actual use of the diamond abrasive belt, the failure of the entire abrasive belt is generally caused by the excessive wear, peeling and falling off of the edge of the diamond abrasive belt.

When the edge of the abrasive belt wears, peels off, or falls off, it will also cause the glass edge of the workpiece to be chamfered. Therefore, once the edge of the abrasive belt wears, peels off, or falls off, although other parts are still good, the entire abrasive belt It must be replaced, thereby significantly reducing the service life of the diamond abrasive belt, resulting in serious waste of the abrasive belt and increasing processing costs
