Abstract: A spindle attachment includes a device body having an attachment surface detachably attached to an end face of a spindle head. Fixed and movable teeth move the body in a direction of an axial line of the spindle to engage the spindle head and the body so as to freely restrict or release rotation of the body with respect to the spindle head. A coil spring urges the body so that the attachment surface is pressed onto the end face of the spindle head with the fixed and movable teeth ready for engagement. A pressure cylinder causes fluid pressure to act on the attachment surface against the spring force to release engagement between the fixed and movable teeth. A key and a key groove transmit rotation of the spindle to the body with the fluid pressure of the cylinder acting on the attachment surface of the device body.

Abstract: A clamping unit for releasably holding a tubular toolholder shank has a base member with a canister sleeve mounted therein. To secure the canister sleeve within the base member and to minimize movement caused by tolerances, retention bolts are threadably mated within the base member to engage a slot within the canister, wherein the relationship between the retention bolt and the slot is such that the retention bolt is intentionally misaligned, so that when engaged with the canister slot, the retention blot resiliently deflects and provides both an axial force and a lateral force upon a canister sleeve.

Abstract: A machining tool comprises a frame mounting an extendable yoke slidable with respect to the frame in a first direction through one or more mounting pillars. A tool motor is mounted on the yoke. A drive mechanism for the yoke is also mounted in the frame, with a drive motor to drive the yoke drive mechanism. A belt is between pulleys on the drive motor and mechanism to transmit drive between them. A rotatable sleeve is around the tool motor and on which sleeve the belt engages on opposite sides of the tool motor, whereby the tool motor can extend between the drive motor and mechanism, thereby resulting in a compact arrangement of the tool.
