Abstract: A cutting tool holder has a holder body and upper and base jaws. An insert receiving pocket is defined between the upper and base jaw, for receiving a cutting insert therein. A resilience recess allows the upper jaw to deflect toward the base jaw. An upper jaw coolant channel has an upper jaw inlet, opening out to the resilience recess, and an upper jaw outlet, opening out to a front end of the upper jaw. A holder body coolant channel has a holder body outlet, opening out to the resilience recess, spaced apart from the upper jaw inlet. A compressible tool coolant plug, made of compressible material, is inserted into the resilience recess. The plug has a plug coolant channel opening out toward the upper jaw inlet and the holder body outlet, forming a fluid path from the holder body coolant channel to the upper jaw coolant channel.

The tightening part is connected to the basic body via a joint around which the tightening part is pivoted to press the cutting insert against the insert seat by a front finger. The rear fixing part includes a first channel having an inlet and an outlet for feed of a fluid toward the cutting insert. The tightening part includes an internal, second channel that extends between an inlet and an outlet.

Abstract: A holder for a cutting bit of metal-cutting material, typically employed in a metal-cutting lathe, incorporates fixed side rake and fixed back rake. The invention makes use of straight tool bits of uniform cross-section that are much longer than they are wide. This invention allows for substantially simplified sharpening of the bit, and in one embodiment substantially simplified adjustment of the height of the cutting tip of the bit. The sharpening procedure allows for much more efficient use of the tool bit material as compared to conventional toolholders and sharpening procedures. Preferred embodiments of the present invention allow for easily producing a bit geometry that will both turn and face without adjusting the position of the toolholder. One embodiment places the tool bit in a highly unorthodox “nearly axial” orientation such that the axis of the bit is fairly close to parallel to the axis of the lathe.

The tube member has an inlet for connection to a cooling agent source and an outlet for leading the cooling agent in a direction towards the cutting insert.

Abstract: A rotary cutter head includes a rotary body, resilient clamping arm, and at least one cutting blade. The clamping arm clamps the cutting blade radially inwardly first rather than in a circumferential direction in order to positively lock the cutting blade radially, and thereby prevent the cutting blade from migrating out of position slightly during high speed rotation of the cutter head.

Abstract: A cutting tool assembly (14) including a tool holder (20) having a removeable clamp (20a). A cutting insert support blade member (16) is removably held in the tool holder by the clamp (20a). The cutting insert support blade (16) includes at least one, preferably two, insert receiving pockets (30). The pockets (30) are defined by a body portion (16b) and a clamp portion (16a) joined together by an integrally formed resilient or deformable portion (16c) which permits slight resilient movement between the clamping and body portions to facilitate the installation of a cutting insert (18) in a pocket. When the insert support blade (16) is mounted in the tool holder (20), the clamp inserts clamping forces to the clamping portion (16a) of the insert support blade which serves to secure the insert support blade to the tool holder and exert clamping forces on an insert (18) held in the pocket.

Abstract: A self contained, toolless quick change tool holder for cutter inserts on machine tools comprises a housing having at least one seat portion which is adapted to receive and conform to the shape of a cutter insert.

In addition, the pivoting arm has an arm extending from the pivot opposite the clamp portion. Lastly, a cam is engaged by a distal end of the arm. The cam has a clamp position which forces the clamp portion to engage a cutter insert and a release position which forces the clamp portion to disengage from a cutter insert to allow thereof. The cam moves between the release position and the clamp position.

Abstract: A tool holder for holding a cutting insert includes a head on which an insert-support surface is disposed. A plate is mounted on the head by a serrated connection, the head including fingers that form side surfaces disposed on opposing sides of the support surface.

Abstract: Disclosed is a cutting tool assembly having a hard, wear resistant insert, a shim and a blade body. The shim has a rearwardly extending recess for receiving the insert. The insert abuts against a top, bottom and rear portion of the shim recess. The shim recess tapers toward the open end of the shim recess to springingly hold the insert. The blade body has a downwardly and rearwardly extending recess on a first end for receiving the shim and insert. The blade body recess is also inclined to the longitudinal axis of the blade body. The blade body recess tapers toward the blade body so as to wedgingly hold the shim and insert.

Abstract: The holder comprises a pair of clamp members fitted with recesses to grasp a linear segment of a tool. These members are pivotally secured together on one side and secured by machine screws or the like near the opposite side. The lower clamp member is fastened in such a way that the upper clamp member may undergo pivotal movement relative to the fastened lower clamp member when the machine screws or the like are loosened. Particularly desirable combinations and positioning of parts for effecting such fastening are described. Also described are (i) a particularly desirable interlocking construction for pivotally securing the clamp members together along one side without actually fastening them together along that side, and (ii) other preferred features which may be employed in the device.

Abstract: A milling cutterhead provided with slots for receiving indexable, disc-shaped cutting bits mounted in individual nest plates. The cutterhead is a generally cylindrical body comprising two concentric body parts, namely, a main member having a circumferential rim portion and an interior ring member which mates with and fits tightly within that rim portion. The nest-receiving slots are cut through the full radial width of the rim portion, and the outer circumference of the interior ring forms the inner walls of the slots. Each nest plate supports more than one-half the circumference of its respective indexable bit at three or more spaced locations so that any inserted bit, no matter how indexed, will have either its radial or axial diameter substantially aligned in a predetermined plane, thereby assuring that the cutting edge of each indexable disc-shaped bit will be positioned to an axial or radial accuracy equal to or less than one-half the diametral tolerance for such disc-shaped bits.

Abstract: A bottom face mill having an elongated body that has a pair of clamping jaws formed on the front end thereof. The clamping jaws are spaced apart by a V-shaped notch which terminates at its inner end at the front end of a transverse, longitudinally extended slot. A triangular cutting tool is held in the V-shaped notch by a pair of retaining pins and a clamping screw which forces the clamping jaws into a releasable clamping engagement with the triangular cutting tool.

Abstract: An adjustable boring tool including an axial shank and a socket for mounting a cylindrical boring bar with an offset axis clamped in adjustable position through transverse and longitudinally slotted segments on one side of the socket together with a transverse screw for clamping the slotted segments against the boring bar.

Abstract: A lathe tool holder has a straight supporting arm and a clamping outer end formed by slotting the outer end in a horizontal central plane to define clamping jaws having opposed dovetail portions which when urged together by a clamping screw grip a resilient tool bit adapter having sides compressible by the jaws to grip a tool bit. Different tool bit adapters are used having socket-like bit-receiving openings which are either parallel to the plane of the slot in the holder or inclined with respect thereto, depending upon the type of work or direction of cut. A drilled hole extends vertically entirely through both jaws, and is tapped to form threads therein which lie on a nominally continuous helix, to receive the clamping screw. The clamping screw is threaded at its end remote from the head for a length which does not exceed the thickness of a single jaw.
