Abstract:
An adaptor for eliminating health injurious noise from a cutting tool (1; 11) for machining a work piece, said adaptor (6; 16) being arranged to be clamped in a clamping section of a tool machine, and where said tool (1; 11) is clamped into said adaptor (6; 16), which comprisesa tool clamping part (3; 13) in which said tool (1; 11) is clamped,an adaptor clamping part (5; 15) which enters into clamping engagement with said clamping section of said tool machine when said adaptor (6; 16) is clamped therein, andat least one elastic damping member (4; 14) arranged substantially between said tool clamping part (3; 13) and said adaptor clamping part (5; 15),characterized in thatsaid adaptor clamping part (5; 15) and said tool clamping part (3; 13) are supported mutually only by means of at least one support bearing (2; 12) which provides substantially free relative movement capability for said parts (3, 5; 13, 15) in one degree of freedom selected so that the movement gives negligible influence on machined dimension or surface quality of the work piece, and thatsaid at least one elastic damping member (4; 14) being fixed to both said tool clamping part (3; 13) and said adaptor clamping part (5; 15) and being arranged to restrict said relative movement to an oscillation about a point of equilibrium, the material characteristics and dimensions of said at least one damping member (4; 14) being chosen to provide a predetermined spring constant and damping coefficient for achieving relocation of vibrational energy from health damaging frequencies to acceptable frequencies.
