What is a diamond grinding wheel

2019-08-13 1329

Diamond grinding wheel is a circular solid grinding tool with a through hole in the center, made of diamond abrasive as the material and metal powder, resin powder, ceramic, and electroplating metal as the bonding agent. It is called diamond grinding wheel.


Composition:


The structure of diamond grinding wheels generally consists of three parts: the working layer, the substrate, and the transition layer.


1. The working layer, also known as the diamond layer, is composed of abrasives, binders, and fillers, and is the working diamond grinding wheel part of the grinding wheel.

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


3. The substrate is used to receive the abrasive layer and is firmly clamped onto the grinding spindle with a flange during use. Generally, steel and alloy steel powder are used as substrates for metal bonding products; The resin binder uses aluminum alloy and bakelite as the substrate. It is processed from aluminum, steel, or bakelite and serves as a support for the working layer and for clamping and grinding tools.


Usage:


Due to the characteristics of high hardness, high compressive strength, and good wear resistance of diamond abrasives, diamond grinding tools have become an ideal tool for grinding hard and brittle materials and hard alloys in grinding. They not only have high efficiency and precision, but also have good roughness, low grinding tool consumption, and long service life. Together, they can also improve labor conditions. Therefore, it is widely used for low iron content metal and non-metallic hard brittle materials that are difficult to process with general grinding tools, such as hard alloys, high aluminum ceramics, optical glass, agate gemstones, semiconductor materials, stone materials, etc.
