Diamond grinding wheels, also known as bonded abrasives

  Diamond grinding wheels, also known as bonded abrasives, diamond grinding wheels by ordinary abrasive solid binding agent to form a certain shape (mostly circular, the central through-hole), and has a certain strength abrasive. Diamond grinding wheels generally consists of abrasive, binder and pore structure, which is often referred to as abrasive three parts of three elements. According to different classification binding agent, a common ceramic (binding agent) wheel, resin (binder) wheel, rubber (Abrasive grinding wheels ) wheel. Abrasive wheel is one of the most widely largest amount, use face, high-speed rotation, can cylindrical, inner circle, plane and a variety of surfaces such as metal or nonmetal type workpieces when using coarse grinding, fine grinding and half grinding and grooving and abrasives grinding wheels  and so on. Diamond grinding wheels grinding process is the most important one class abrasive. Abrasive wheel is a binding agent was added to the porous body by the pressure of the blank, made ​​of dried and calcined. Since abrasives, binding agents and different manufacturing processes, a large difference in the characteristics of the wheel, so the quality of the grinding process, productivity and economy has an important effect. Diamond grinding wheels properties mainly determined by the abrasive particle size, binder, hardness, structure, shape and size and other factors.

Diamond grinding cup wheels is the most important one class abrasive

Since abrasives, binding agents and different manufacturing processes, a large difference in the characteristics of the wheel, so the quality of the grinding process, productivity and economy has an important effect. The main characteristics of the grinding wheel is determined by the abrasive particle size, binder, hardness, structure, shape and size and other factors.Also known as the abrasive wheel is binding agent by ordinary abrasive solid form a certain shape (mostly circular, the central Diamond core drilling machines , and has a certain strength abrasive. Which generally consists of abrasives, binders and pores form, these three parts is often called the three elements of abrasive binders according to different classification, a common ceramic (binding agent) wheel, resin (binder) wheel, rubber cbn grinding wheels  wheel. Abrasive diamond grinding cup wheels is one of the most widely largest amount, use face, high-speed rotation, can cylindrical, inner circle, plane and a variety of surfaces such as metal or nonmetal type workpieces when using coarse grinding, fine grinding and half grinding and grooving and cutting and so on. Grinding wheel is the most important one class abrasive. Abrasive wheel is a binding agent was added to the porous body by the pressure of the blank, made of dried and calcined.

Wheel sizes and shapes to choose from.


  According to the structure and needs grinding machine, grinding wheels made ​​of various shapes and sizes. The outer diameter of the cbn grinding wheel should be as the election was bigger, in order to improve the peripheral speed of the wheel, so to improve productivity and the surface roughness of the grinding favorable. In addition, in the license conditions of the machine stiffness and power, such as the choice of the width of the largerabrasive grinding wheel, to receive the same roughness to increase productivity and reduce the effect, but when the grinding material having a high heat-sensitive, in order to avoid burns and the workpiece surface cracks, wheel width should be appropriately reduced.
