This reduces wheel wear. Roughness and grinding force are also reduced. Because of the lower grinding force, size errors are reduced. Optimum removal per grain can be maintained by increasing the work speed in the same proportion as the wheel speed. This maintains the grinding force approximately at a constant level.

grinding) + work rest. - Regulating wheel of rubber bonded abrasives. It rotates the work by friction, with a speed of 0.25 –1 m/s. (much slower than the wheel) - Both wheel rotate in the same direction to move the work. - The work rest support the work. The axial movement of the work –piece is obtained by tilting regulating wheel at (5 0 ...

How To Set Work Head Speed In Cylindrical Grinding Machine

Aug 16, 2011· The most widely used workholding method for cylindrical grinding is done between centers. Between-centers grinding does not require a centerless ground workpiece. In fact, many agree that the only way to create a perfectly round part from raw stock, in one setup, is to grind between centers. Many tool designers start with this methodology in mind.
