Diamond grinding wheel profile
The structure of diamond grinding wheel is composed of three parts, the working layer, the matrix and the transition layer.
The working layer is also called the diamond layer, which is composed of abrasive, binder and filler, and is a part of the working diamond wheel (8) of the grinding wheel. The transition layer is also known as the non diamond layer, which is composed of a bond, a metal powder and a filler, which is a part of the diamond layer which is firmly attached to the substrate.
The base material is used to carry on the abrasive layer, and the flange plate is firmly clamped on the grinding spindle when using. General metal bonded products selected steel, alloy steel powder as matrix resin binder; use aluminum alloy as matrix, bakelite. Made of aluminum, steel or bakelite processing, supporting layer and clamping abrasive role. Wheel molding quality and the use of the accuracy of the high and low have a great relationship with the matrix.
The characteristics of diamond grinding wheel include the type, size, concentration, bond and shape size of diamond abrasive.
Because of the characteristics of diamond abrasive (high hardness, high compressive strength, good abrasion resistance), so that the diamond abrasive tools in the grinding process to become the ideal tool for grinding hard brittle material and hard alloy, not only high efficiency, high precision, but also good roughness, less consumption, long service life, but also improve labor conditions. So it is widely used in ordinary abrasives are difficult to produce low iron content of metal and non-metallic hard and brittle materials, such as hard alloy, high aluminum porcelain, optical glass, agate gem, semiconductor materials, such as stone.
Diamond grinding wheel can be divided into: resin bonded diamond grinding wheel, ceramic bond diamond grinding wheel, metal bonded diamond grinding wheel (bronze bonded diamond grinding wheel)
Diamond grinding wheel according to the production process can be divided into: sintered diamond grinding wheel (resin bonded diamond grinding wheel; diamond bonded diamond grinding wheel; metal bond diamond grinding wheel).
Diamond grinding wheel can be divided into: grinding diamond grinding wheel, diamond grinding wheel (diamond wheel grinding wheel), diamond grinding wheel, diamond grinding wheel with no core, diamond grinding wheel, diamond grinding wheel (also known as diamond cutting blade); diamond saw blade.
Diamond grinding wheel according to the appearance or shape can be divided into: parallel to the wheel; cylindrical grinding wheel; cup wheel; bowl wheel; dish shaped grinding wheel; grinding wheel; disc and so on.
The diamond grinding wheel is used for grinding and grinding of hard brittle materials such as glass, ceramic, ferrite, semiconductor materials and metal materials, and the machining of hard alloy material, electrolytic grinding, and grinding of diamond bit.
