Bronze bond diamond wheel

Bronze diamond wheels with high-temperature sintering manufacturing, the combination of high strength , good formability , high temperature , thermal conductivity and good wear dry cut blades  resistance , extremely long life , can withstand greater loads.
Widely used in glass, ceramics , ferrite , semiconductor materials, stone and other hard and brittle material and a metal material of the grinding process .
The characteristic features of the grinding wheel abrasive particle size , binder, hardness, structure , and other factors determined shape and size . In superhard grinding wheel hardness and organizations are generally neglects to mention .
Abrasive grinding wheel is the main raw material manufacturing , cutting directly responsible work . . Diamond : common materials suitable for processing high wheel hard to process hard brittle concrete diamond blades  metal and nonmetal materials . Such as cemented carbide , optical glass , ceramics , stone , and other semiconductor materials .
Particle size refers to the size of the abrasive particles , the size of a particle numerals. GB provides two kinds of abrasive powder particle size and number. Generally speaking, use coarse abrasive coarse ( size number smaller ) , abrasive grinding to a smaller ( larger particle number ) ; powder used for grinding and other precision machining and ultra- precision machining. Ceramic diamond wheel size range generally w1.5 ~ 80/100
The role of binding agent binding agent is bonded abrasive having a given strength and shape of the wheel. Wheel strength, impact resistance , heat resistance and corrosion resistance , depending on the binding agent performance . The binding agents are used  tct circular saw blade vitrified (V), the resin binding agent (B), the rubber binding agent (R) and the metal binding agent (M) and so on . Vitrified bond : the most widely applicable to cylindrical, round, flat , centerless grinding and profile grinding wheel , etc. ; resin bond : for cutting and slotted sheet wheel and high-speed grinding wheel ; rubber combined agent: guide wheel for centerless grinding , polishing wheel ; metal bond : for diamond grinding wheel .
