  • Patent number: 10744571
    Abstract: A rotating tool includes a circumferential surface formed with a tool anchorage arrangement. The tool anchorage arrangement follows a stepped path. The tool anchorage arrangement includes an entry recess and, subsequent thereto, a radial recess and, subsequent thereto, an axial recess. Additional radial and axial recesses may be alternated to increase the number of steps, thereby extending the length of the stepped path.

  • Patent number: 9120164
    Abstract: A cutting tool includes first and second components, configured for differential coupling with each other. The first and second components each include peripheral and central coupling threads which each extend in a helical direction about a component axis of the respective component. Each component's peripheral and central coupling threads are axially offset with respect to each other. The first and second components each include a radial stop surface located at the respective peripheral coupling thread. In an assembled position of the cutting tool, the radial stop surfaces abut each other and the peripheral and central coupling threads of the first component threadingly engage the peripheral and central coupling threads of the second component, respectively, forming a differential tool coupling between the first and second components.

  • Patent number: 9022393
    Abstract: A cutting tool includes a chuck, a compressible conical collet and a lock nut for locking the collet. The cutting tool lock nut has a nut portion with a threaded portion for threading with the chuck, and a locking portion with a collet-locking surface formed with angled coolant grooves thereon. The collet-locking surface presses on the collet head, thereby compressing it to grip a tool shank in a collet bore thereof. As the locking portion presses only against a peripheral surface of the collet head, the lock nut is suitable for locking collets with different bore diameters. When the chuck is provided with a coolant fluid, the coolant fluid flows through the chuck and through the collet towards the locking portion, passing through the coolant notches between the locking portion and the collet head, and sprayed towards a location along the tool shank.

  • Patent number: 8752843
    Abstract: A collet has seal bores formed in interspaces of the collet. The seal bores are oriented at an acute angle ? 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.

  • Patent number: 8696270
    Abstract: A cutting tool having a cutting head removably secured to a shank by frictional forces maintained between a male coupling member located in a female coupling member. Support surfaces of the male coupling member engage support walls of the female coupling member. The support surfaces lie on a common cylinder having a larger diameter than a common cylinder on which the support walls lie. The support walls are located on a circumferentially continuous bore wall of the female coupling member.

  • Patent number: 8668411
    Abstract: A cutting tool has a cutting insert and a holder. The cutting insert has a cutting portion and an insert shank with a cylindrical portion and a non-cylindrical portion. The holder has a clamping portion which has a clamping sleeve and a cage located therein. The cage includes a load member housing with a load member. The cage has a major abutment wall adjacent to a minor abutment wall. The clamping sleeve has first and second inner sections defined by points P1 and P2. A point P3 divides the second inner section into first and second portions. The clamping sleeve is rotatable between a secured and a released position of the cutting tool. In the secured position, the non-cylindrical portion abuts the major abutment wall, the cylindrical portion abuts both the minor abutment wall and the load member, and the load member abuts the first portion.

  • Patent number: 8616560
    Abstract: A chuck for clamping an article has a receiving portion including a receiving bore having a longitudinal axis L, and a radially inwardly facing contoured clamping and receiving inner surface. A clamping sleeve is accommodated in the receiving bore and is rotatable between a releasing position and a securing position. The contoured clamping and receiving surface has one or more clamping segments, each clamping segment having a ramp between a trough and a crest, a second ramp between the crest and a depression, and a third ramp between the depression and the succeeding stop ridge. Rotating the clamping sleeve within the receiving bore causes one or more rollers associated with each clamping segment to cooperate with the contoured clamping surface to effect the releasing and the securing of the article.

  • Patent number: 8511948
    Abstract: A tool clamping mechanism connects a first member to a second member. The first member has a cylindrical stem with a coupling tooth projecting from the stem. The second member has a clamping cavity formed by the union of a gripping bore and an access hole. The access hole has an access bore and a tooth access hole formed to accommodate the stem and the coupling tooth respectively. The stem diameter of the stem is larger than the gripping bore diameter of the gripping bore. The clamping cavity further has a coupling recess for accommodating the coupling tooth. The coupling recess has a drive surface for engaging a driven surface located on the coupling tooth to create a force which pushes the stem from the access bore into the gripping bore and helps prevent separation of the two members.

  • Patent number: 8434973
    Abstract: A clamping mechanism includes a male portion and a female portion. The male portion has a forwardly extending locking protrusion, and an alignment protrusion extending forwardly of the locking protrusion. A rear of the female portion has a forwardly extending locking bore and an alignment bore extending forwardly from a front end of the locking bore. The locking bore has an insertion bore portion which merges with a gripping bore portion. The insertion bore portion has an insertion bore axis while the gripping bore portion has a gripping bore axis that is spaced apart by a non-zero first distance from the insertion bore axis. In a clamped position, the alignment protrusion abuts a portion of the alignment bore and the locking protrusion abuts the gripping bore portion along a gripping angular extension, thereby forming a circumferential interference fit.
