What is diamond wheel

2019-07-27 160

The diamond grinding wheel is made of diamond abrasive material, which is bonded by metal powder, resin powder, ceramic and electroplated metal.


The structure of diamond grinding wheel generally consists of three parts: working layer, base layer and transition layer.

1. The working layer, also known as diamond layer, is composed of abrasive, binder and filler, and is the working part of diamond grinding wheel of grinding wheel.

Emery wheel

2. The transition layer, also known as the non-diamond layer, is composed of binder, metal powder and filler, which is the part of the diamond layer firmly connected to the substrate.

3, the matrix, used to accept the abrasive layer, and in the use of flange firmly clamp on the grinding spindle.General metal binder products choose steel, alloy steel powder as the matrix;Resin binder USES aluminum alloy and bakelite as matrix.It is made of aluminum, steel or bakelite, which can support the working layer and install the clamping tool.


Because diamond abrasives have high hardness, high compressive strength and good abrasion resistance, diamond abrasives become the ideal material for grinding hard and brittle materials and hard alloys in the grinding process.Therefore, it is widely used for hard and brittle materials with low iron content, such as hard alloy, high alumina porcelain, optical glass, agate stones, semiconductor materials and stone materials.
