Deformation of resin cutting abrasive wheels
The deformation of resin grinding wheel is a difficult problem that has puzzled the China grinding wheel suppliers of resin China long life grinding wheel for a long time. The root cause of deformation is the uneven microstructure in the effective area of the wheel, which leads to the uneven stress in the hardening process of the product.
Manufacturers of resin-bonded China long life grinding wheels should concentrate on solving the problems of mixture uniformity, molding uniformity and mesh stability. Only by gradually solving the above three problems can the deformation of resin-bonded grinding wheels (mainly cutting wheels) be solved.
Application field of grinding wheel
In general, peeling grinding is mainly applied in the following two areas:
(1) Replacing the traditional shaping cut-in grinding: CBN grinding wheels do not need to change grinding wheels and dressing tools frequently when processing different workpieces, which reduces grinding settings and adjustment time and improves processing flexibility; at the same time, the contact area between the fast working grinding wheel and the workpiece is smaller when peeling grinding (Fig. 3), so the required grinding force is also greater. Small, avoid grinding vibration and workpiece deformation due to excessive grinding force, and improve machining accuracy.
(2) Substitute for hard turning or as the follow-up process of hard turning: The use of CBN wheels for peeling grinding can improve the dimensional accuracy and surface processing quality of the workpiece.
