A diamond-shaped abrasive device is used as a raw material, and a metal-made powder, a resin powder, a ceramic, and a plated metal are respectively used as a bonding agent, and a circularly-shaped fixed abrasive having a through-hole in the center is called a diamond-cut piece.

structure
The structure of the diamond 5 inch resin cutting disc for metal generally consists of a working layer, a base body and a transition layer.
The working layer, also known as the diamond layer, consists of abrasives, binders and fillers and is the working part of the cutting blade. The transition layer, also called a non-diamond layer, consists of a binder, a metal powder, and a filler, and is a portion that firmly bonds the diamond layer to the substrate.
The base body is used to receive the abrasive layer and is firmly clamped to the grinding machine spindle by a flange during use. Generally, the metal bond product is selected from steel and alloy steel powder as the matrix; the resin bond is selected from aluminum alloy and bakelite as the matrix. It is made of aluminum, steel or bakelite and functions as a supporting working layer and a chucking tool. The quality of the cutting piece and the accuracy of its use are closely related to the substrate.
characteristic
The characteristics of diamond cutting sheets include the type, particle size, concentration, binder and shape size of the diamond abrasive.
use
Due to the characteristics of diamond abrasives (high hardness, high compressive strength and good wear resistance), diamond grinding tools are an ideal tool for grinding hard and brittle materials and hard alloys in grinding, which is not only efficient but also highly accurate. High, and the roughness is good, the abrasives are used less, the service life is long, and the working conditions can be improved. Therefore, it is widely used in low-iron content metal and non-metal hard and brittle materials, such as cemented carbide, high-aluminum porcelain, optical glass, agate gemstone, semiconductor material, stone, etc., which are difficult to process with ordinary abrasive tools.
classification
The diamond cutting piece can be divided into: resin bond diamond fiber cutting disc Chinese supplier; ceramic bond diamond cutting piece; metal bond diamond cutting piece (bronze bond diamond cutting piece) according to the bonding agent.
According to the production process, the diamond cutting piece can be divided into: sintered diamond cutting piece (resin bond diamond cutting piece; ceramic bond diamond cutting piece; metal bond diamond cutting piece); electroplated diamond cutting piece; brazed diamond cutting piece.
The diamond cutting piece can be divided into: diamond cutting piece for grinding diamond; diamond cutting piece for grinding hard alloy (diamond cutting blade); diamond cutting piece for grinding diamond composite piece; centerless grinding diamond for coreless grinding machine Cutting piece; diamond cutting piece for grinding ceramic products; diamond cutting piece for cutting (also called diamond cutting piece); diamond saw blade.
The diamond cutting piece can be divided into: parallel cutting piece; cylindrical cutting piece; cup-shaped cutting piece; bowl-shaped cutting piece; dish-shaped cutting piece; edging cutting piece; grinding plate, etc. according to appearance or shape.
application
Diamond cutting discs are used for grinding of hard and brittle materials and metal materials such as glass, ceramics, ferrites, semiconductor materials, shape processing of hard alloy materials, electrolytic grinding, and grinding of diamond bits with grinding centers. Equal heavy-duty cutting, featuring good wear resistance, high efficiency and long service life.
