Abstract: A reconditioned tool comprises a cylindrical insert cut from a damaged tool, such as a hog mill, with a milling face formed on one end and a transverse dovetail tenon cut in the other end. The dovetail tenon engages a transverse dovetail mortise in the end face of a cylindrical holder. A transverse slot in the holder splits the end of the holder into two axially extending end sections each of which includes one-half of the dovetail mortise. A clamping device, such as a bolt, draws the two end sections of the holder together to pull the insert firmly against the end faceof the holder through wedging action of the two halves of the dovetail mortise against the dovetail tenon. A locking pin inserted through aligned transverse grooves in the holder and insert prevents a lateral displacement of the insert relative to the holder.

Abstract: The invention relates to a tool for chip removal comprising a cutting insert mechanically clampable within a slot of a holder. The insert is clamped by the resilient force arising during deflection of a clamping arm provided in the holder. The insert and the clamping arm are engageable at contact regions separated from each other, a first contact region of which forms an acute angle relative to the lower side of the insert.

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 invention relates to a chip cutting tool comprising at least one cutting insert, which is clamped in a holder body. The insert is clamped by means of the resilient force arising from the bending of a clamping arm which is attached to the holder body. During mounting of the insert the latter slides against the clamping arm, thereby bending same in such a way that a larger bending of the clamping arm occurs during an initial phase of the mounting of the insert than during the final phase of this mounting.

Abstract: A tool for cutting material includes a holding member having a slit-like opening forming first and second spaced jaws, a cutter insert mounted between the spaced jaws in the slit-like opening, and a positioning arrangement on the holding member positioning the cutter insert in the opening, whereby the spaced jaws hold the cutter insert with a predetermined clamping pressure providing for proportional increase of the clamping pressure relative to the cutting pressure applied to the cutter insert.

Abstract: Tool systems using replaceable cutting inserts and the insert for use in the systems wherein the tool holders have wedge shaped recesses for holding the inserts which are also wedge shaped and have shoulder means thereon that maintains the distance the cutting edge of the insert extends from the holder predetermined during operation of the system.

Abstract: The present invention relates to a cutting tool for milling, boring or turning, comprising a holder shank (10) with a slotted end and a blade (13) clamped in the slotted end of the holder shank (10) by means of a clamping screw (16) which loosely extends through the blade (13). The blade (13) is provided with a recess (22) having radially displaced abutment surfaces (24A,24B) that are to abut outer edges (21A,21B) of the slot so as to radially center blade (13) in the slot (17) when tightening the screw (16). Furthermore, the invention relates to a blade (13) for use in connection with the above-mentioned holder shank (10).

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 highly productive completely automatic tracing shaper machine tool performs sequential operations without manual attention permitting a single operator to simultaneously run several machines without being exposed to the shaper heads of the machine. The tracing shaper machine tool has a track mounted vacuum feed table or chuck clamping thereon a template or pattern and the wood workpiece to be shaped. The table is manually positioned on the track to accommodate a wide range of workpiece sizes and this initially positioned table or chuck with the stacked template and workpiece vacuum clamped thereon is automatically biased toward a selectable speed driven upright shaper tool carrying spindle with a rotatable follower bearing surrounding the spindle receiving the periphery of the template thereagainst at a constant pressure. The feed table or chuck is rotated to provide a desired feed rate of the workpiece to the shaper tool, and this rotation continues somewhat beyond a 360.degree.

Abstract: A machine cutting tool comprising a holder into which replaceable cutting inserts may be inserted in a self-gripping manner. The holder and cuttng inserts each have two contact surfaces opposite each other of an approximate circular form about the center of rotation of the cuttng insert. When in working position, the contact surfaces are developed complementary to one another and provided with guides. The cutting insert can be inserted into the holder with its narrow side and can be securely locked by turning it in the direction of the force acting on the cutting edge during operation. A detachment of the cutting insert during operation is impossible. The cutting insert preferably has two diametrically opposite cutting edges.

Abstract: A support blade for a cutting tool insert is disclosed featuring a unitary clamping arrangement for the insert actuated by a camming member permanently positioned in the blade.

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.
