Sintered diamond wheel

Sintered metal-bonded grinding wheels mostly bronze and other metals as a binder, with the manufacture of high-temperature sintering method, which combines high strength, good formability, high temperature, thermal conductivity, good wear resistance, long life, can withstand greater loads. Wheel sintering process because inevitably kept the contraction and deformation, so use a facelift before the grinding wheel, but wheel Synthetic diamond  difficult. Production is often used grinding wheel dressing roller shaping method is not only time consuming and laborious sintered diamond wheels, diamond particle shedding and trimming process more wheel dressing itself consumes large plastic lower accuracy.
In recent years, scholars from various countries have launched a special processing method applied metal bond diamond wheel dresser research work, mainly electrolytic dressing, method  polycrystalline diamond dressing method. Electrolytic dressing method is fast, but shaping accuracy is not high; EDM shaping trimming method, high precision, can be either plastic dressing, but the plastic slowly; composite dressing method has spark composite electrolytic dressing, mechanical chemical compound trimming France etc., dressing better, but the system is more complex, so sintered diamond wheel dressing the problem still has not been solved.
Further, since the grinding wheel manufacturing process determines the random surface morphology, each grain geometry, distribution and high degree of inconsistency which the cutting edge, so that only a small number of high grinding the cutting edges cut into the workpiece, the grinding quality of the grinding limit further improve the efficiency.
Electroplated diamond grinding wheel
Electroplated diamond grinding wheel advantages:
① plating process is simple, less investment, ease of manufacture;
② without dressing, easy to use;
③ monolayer structure determines it can reach very high operating speed, now abroad, has reached 250 ~ 300m / s;
④ Although only a single layer of diamond, but there is still enough life;
⑤ For high accuracy, roller wheels, electroplated unique manufacturing method.
