摘要： A rotary tool holder assembly comprising a collet (2) carried by a shaft (1). The collet (2) is moveable relative to the shaft (1) between a tool gripping position, in which an inserted tool can be gripped for rotation, and a tool release position. In some cases, the shaft (1) comprises a bore, an inner surface of which is shaped for contact with an outer surface of the collet (2). The shaft (1) and collet (2) are shaped such that when the rotary tool holder assembly is rotated at a predetermined high speed the shape of the inner surface of the shaft (1) substantially matches the shape of the outer surface of the collet (2). A friction reducing coating is provided between at least a portion of the inner surface of the shaft (1) and the outer surface of the collet (2). In alternatives, particular parts of the rotary tool holder may have a friction reducing coating.

摘要： The chuck includes a body with an axial recess and a transverse opening intersecting the recess. First and second cam members are disposed at least partially within the transverse opening and have first and second passages, respectively, which squeeze a cylindrical, slitted inner sleeve that holds the tool shank during rotation of the chuck. The inner sleeve is spring-biased for axial movement relative to the body and has a tapered upper end that is compressed when engaging a tapered retainer sleeve and thereby retains the tool shank during nonrotation of the chuck. An outer sleeve including comolded inner and outer shells, is configured and disposed to move axially about the body. A remote actuating member effects axial movement of the outer sleeve and inner sleeves to permit insertion or withdrawal of the tool shank from the chuck. An engagement mechanism connects the chuck to a drive spindle and also has a mounting mechanism for facilitating automated mounting of the chuck to a drive spindle.

摘要： A high speed system (50) for drilling of very small holes in workpieces (137) such as printed circuit boards. The X-Y positioning system includes air bearings (120) to provide lift between the stationary guide beams (60, 62), the cross beam (65), and the top table (70), and further includes a vacuum preloading apparatus (128). The top table (70) is a light honeycomb structure (71, 72, 73), whose effective rigidity is virtually that of the guide beams (60, 62) due to the vacuum preloading. The system (50) includes a conventional spindle (85) and a high speed spindle (81). The high speed spindle (81) includes a stationary body (156) carrying the stator (195, 196) of the drive motor. Only the spindle rotor (160) is translated along the Z axis to perform drilling movements. The rotor (160) is supported within the body (156) by rotary and linear air bearings (179, 187), and is axially driven by a linear motor (210, 220). A tool changer (95) loaded by clips (350) carrying the drilling bits (400) is mounted on the top work table (70). A vacuum hold-down apparatus (140) secures the workpieces (137) to a drilling station.

摘要： Mandrin destiné à fixer une pièce à usiner (7) pendant le tournage du bois. Le mandrin comporte un corps (3) pouvant être fixé à une extrémité sur un tour (1) et possédant à l'autre extrémité deux excentriques (8, 9) radialement opposés et présentant une excentricité égale. Chaque excentrique est entouré par ou entoure un mors de serrage (5, 6) respectivement, lesquels mors sont évidés de concert pour former une surface d'extrémité réciproque. Les mors de serrage sont agencés de manière à pouvoir être tournés d'un demi tour par rapport au corps (3), formant ainsi ensemble à une position d'extrémité de rotation un disque cylindrique, tandis qu'à l'autre position d'extrémité de rotation, ils sont déplacés radialement dans des sens opposés par rapport à eux-mêmes.

摘要： A chuck (1) for rotating around a rotation axis (X A ) a centrifugal separation bowl (2) secured thereto includes a vat-shaped body (11) for receiving a lower end portion (22) of the separation bowl (2) secured therein with a peripheral rim (28) of the chuck (1) surrounding an outer flank (23) of the separation bowl (2). The chuck includes a plurality of clutching systems to co-operate with the flank of the separation bowl (2) in securing it to the chuck (1). The clutching systems include a channel (30) formed in the chuck body (11) with an arcuate path in the peripheral rim (28) of the chuck body. A chain of translatory bodies (16, 17, 18, 19, 20) arranged within the channel (30) includes a proximal translatory body (16) and a distal translatory body (20) in the chain, whereby a force (15, 16, 21) acting on the proximal body (16) and directed outwardly of the rotation axis (X A ) is transmitted through the chain of translatory bodies to the distal translatory body (20) to urge it inwardly towards the rotation axis (X A ) to clutch the outer flank (23) of the separation bowl (2) whereby the separation bowl (2) is secured to the rotary chuck (1).
