Title:
GRINDER FOR INGOT
Document Type and Number:
WIPO Patent Application WO/2011/027505
Kind Code:
A1
Abstract:
A grinder for an ingot is provided with a grinding means for performing traverse grinding by bringing a rough grinding wheel for rough grinding and a precise grinding wheel for precise grinding which is arranged inside of the rough grinding wheel, into contact with an outer peripheral surface of an ingot, said rough grinding wheel and said precise grinding wheel being coaxially mounted on a single spindle. The grinder for an ingot performs cylindrical grinding by performing the rough grinding and thereafter the precise grinding by the grinding means while rotating the ingot, or performs plane grinding by performing the rough grinding and thereafter the precise grinding by the grinding means, without rotating the ingot held by a clamp. The grinder for an ingot has a movement means for moving the precise grinding wheel of the grinding means forwardly and backwardly in the axial direction of the spindle. The precise grinding wheel is moved forwardly or backwardly by the movement means to select the wheel to be brought into contact with the ingot in order to grind the ingot. Thus, the grinder for an ingot in which the reduction of the grinding speed is suppressed and the time of the grinding processes can be reduced while limiting the processing strain by machining particularly below 10 μm can be provided.
