Abstract:
An abrasive machine, in particular a grinder for removal of material from an end face of a work piece, said machine comprising a rotatably driven tool, chucking equipment for holding said work piece relative said rotatably driven tool and feeding means for effecting relative displacement between said work piece and said rotatably driven tool,a tubular cylindrical housing extending about a longitudinal axis, said housing having a longitudinal cylindrical inner space extending from a first end of said housing, said cylindrical inner space having a longitudinal axis which is offset from the longitudinal axis of said housing; a shaft arranged in said inner space for angular displacement therein, said shaft being provided with a recess; a motor arranged in said recess; a spindle coupled to said motor, said spindle cooperating with said chucking equipment to hold and rotate said work-piece; a rotatable outer casing peripherally enclosing said tubular cylindrical housing; a lid member connected to said outer casing, said lid member extending radially over said first end of said tubular cylindrical housing such that an inner surface of said lid member faces said first end of said housing, wherein said rotatably driven tool comprises a ring-shaped region of abrasive material carried on said inner surface of said lid member, and said shaft is arranged in said inner space such that when said shaft executes an angular displacement in said inner space, said work piece held by said chucking equipment is caused to approach and contact said ring-shaped region of abrasive material.
