Abstract
A fixture (1) for guidance of a tool having a cutting edge with respect to the periphery of a rotating grinding- or polishing wheel (2), comprising a frame structure that runs along the periphery (6) of the wheel and has a guide formed as a slot (17) with an open outer end, the slot providing a support surface (19) that is sloping relative to the radius of the wheel, and the inner end of the slot terminating radially within the periphery of the wheel on each side thereof, the fixture (1) in one end supported (11) for pivoting motion in a main plane of the wheel and in the other end carrying a separate balance weight (12).

A fixture (1) for guidance of a tool having a cutting edge with respect to the periphery of a rotating grinding or polishing wheel (2), characterized in that the fixture in it's operational position extends mainly along a portion of the periphery (6) of the wheel and has a guide formed as a slot (17) opening away from the periphery of the wheel, the slot providing a support surface (19) for the tool, said support surface (19) being arranged at a sloping angle relative to a radius of the wheel going through the point of contact between the tool edge and the periphery of the wheel, and the inner end of the slot terminating radially within the periphery (6) of the wheel at least on one side thereof, the fixture (1) in one end supported (11) for pivoting motion in a main plane of the wheel and in the other end carrying a separate balance weight by which the fixture is biased towards the periphery (6) of the grinding- or polishing wheel.
The fixture according to any previous claim, characterized in that two side members connect to a back member that embraces opposite sides of an accessible portion of the wheel periphery substantially like a saddle, and the support surface (9) is U-shaped in a planar view.
