Holding Fixture For a Grinding Tool, Grinding Tool and Supporting Body For a Grinding Tool

Abstract

A holding fixture ( 1 ) for a grinding tool ( 30 ) is comprised, in essence, of a first tension plate ( 10 ) and a second tension plate ( 20 ). The first tension plate ( 10 ) can rotate relative to the second tension plate ( 20 ) about an axis (A). The first tension plate ( 10 ) comprises a first bearing surface ( 11 ) and the second tension plate ( 20 ) has a second bearing surface ( 21 ). A supporting body ( 31 ) can be clamped firmly with a first and a second contact surface ( 32, 33 ) between the bearing surfaces ( 11, 21 ). An angle (&agr;, β) is formed between the first and the second bearing surface ( 11, 12 ) of the holding fixture ( 1 ) and/or between the first and the second contact surface ( 32, 33 ) of the supporting body ( 31 ).
