Abstract
A collet has seal bores formed in interspaces of the collet. The seal bores are oriented at an acute angle α to the longitudinal axis of the collet, and extend towards a tool end of the collet, from a clamping surface of the collet to a collet peripheral surface. Adjacent the clamping bore, the collet has stopping surfaces for accurately locating the seals. When inserted into the seal bores, the seals prevent fluid leakage between the clamping bore surface and the peripheral surface of the collet.
Claims22
A collet (14) having a longitudinal collet axis (A) and comprising angled seal bores (50) formed in interspaces (34) of the collet (14), each seal bore (50) extending between an inner end (52) and an outer end (54) thereof;
- the collet (14) comprising a longitudinal clamping bore (36) and a peripheral surface (38) extending between a tool end and a holder end of the clamping bore (36), the clamping bore (36) comprising a clamping surface (42) extending from the tool end;
- wherein:
- the seal bores (50) extend at an acute angle α to the collet axis (A), from the clamping surface (42) to the peripheral surface (38), towards the tool end;
- and
- the inner end (52) of the seal bores (50) partially intersect the clamping bore (36).
A collet (14) having a longitudinal collet axis (A), and comprising:
- a peripheral surface (38) having a plurality of interspaces (34);
- a longitudinal clamping bore (36) extending along the collet axis (A) from a tool end to a holder end, the longitudinal clamping bore comprising a clamping surface (42) proximate the tool end;
- and
- a plurality of angled seal bores (50) formed in the interspaces (34), each seal bore (50) being in fluid communication with the clamping bore and having a seal bore axis (B) which extends at an acute angle α to the collet axis (A);
- wherein:
- only a portion of a cross-section of each seal bore (50) opens out to the clamping bore (36).
