Abstract:
A ball lock assembly having a cutting head (22) and a locking component (24) including a lock rod (94) carrying at least one locking member (105). A positioning assembly (50) operatively connects to the lock rod so that one can move the lock rod between a locked position and an unlocked position. In the locked position the locking member engages the cutting head to hold the cutting head to the locking component. In the unlocked position the locking member does not engage the cutting head so that the cutting head is not held to the locking component.
Abstract:
An apparatus for adapting toolholders (10) which are specifically designed for use with machine tools having quick change tooling systems so that such toolholders may be used with machine tools not equipped with such systems. The apparatus secures to the toolholder shank (45) and provides an intermediate element enabling the toolholder (10) to be secured to such machine tools.
Abstract:
The present invention relates to a milling cutter (10) having a cutter body (12) and a plurality of replaceable tool cartridges (16) circumferentially spaced about the outer periphery of the cutter body. An adjustment mechanism permits adjustment of the tool cartridges (16) in the direction parallel to the axis of rotation of the cutter body (12). The adjustment mechanism includes an adjustment screw (52) threaded into a corresponding bore (54) in the cutter body (12). The head (56) of the adjustment screw (52) projects into an inclined throughbore (60) in the tool cartridge (16). When the adjustment screw (52) is turned, the head (56) of the screw bears against the inner surface of the throughbore (60) causing the tool cartridge (16) to be axially displaced. A locking screw (62) is tightened to secure the tool cartridge (16) in place after it has been adjusted.
Abstract:
An indexable cutting insert (2) is shown capable of cutting operations over a wide range of parameters such as depth of cut or feed rate. The insert has different geometries at certain locations on the cutting surface (22) such that under differing parameters a desirable cutting surface will be in contact with the workpiece.
Abstract:
An insert (10) for insertion into a bore opening (12) formed within a working face (20) of a tool (14) and a method of making the same. The insert includes a head (18) having an integral body (16) adapted for insertion into the bore. The insert has carbide particles adhered to the insert surface to resist removal of the insert from the bore opening.
Abstract:
An expandable holding device for holding a component (115) in which the clamping force is brought about by the solidification and expansion of a fusible alloy (132). The alloy (132) is contained in an expansion chamber (130) defined in part by a thin-walled, expansion sleeve (122). The alloy (132) has a low melting point and expands when it solidifies. The pressure caused by expansion of the fusible alloy radially expands the expansion sleeve (122) causing the expansion sleeve to grip the component (115). To release the component, the alloy (132) is heated and liquified so that the expansion sleeve (122) returns to an unexpanded condition.
Abstract:
Decarburized tungsten carbide powder and a process for producing decarburized tungsten powder from tungsten carbide process. The process includes the step of reacting tungsten carbide powder with wet hydrogen gas at an elevated temperature.
Abstract:
A clamping assembly (14) for releasably holding toolholder (12) having a shank (22) includes a tool support member (32) having a bore extending along a longitudinal axis. A locking mechanism is disposed in the axial bore (44) for securing the toolholder to the support member. The locking mechanism includes a lock rod (104) having first and second contact surfaces mounted in the support member. The lock rod moves along the longitudinal axis between a locked position and a release position. A wedge rod (130) is mounted in the support member for reciprocal movement along an axis angularly disposed with respect to the longtudinal axis. The wedge rod has first and second wedge surfaces which incline in parallel fashion from opposite edges of the wedge rod. First and second force transmitting elements (126) are interposed between the wedge surface of the wedge body and the contact surfaces of the lock rod. When the lock rod is moved in first direction, the first force transmitting element is moved outward with respect to the transverse axis into contact with the first support surface and pushes the lock rod towards a locked position. When the wedge rod is moved in a second direction, the second force transmitting element is moved outward with respect to the transverse axis into engagement with the second contact surface of the lock rod and moves the lock rod towards a release position.
Abstract:
An improved cutting insert (10) for threading applications has chip control features and includes an insert body (12) having end wall regions, sides and top and bottom walls adapted for mounting in a pocket in a holder. The insert body has cutting edges and a notch in the top and bottom sides. The end wall regions each comprise two end walls converging toward one another as they extend from the insert's sides, forming at the juncture with the respective top and bottom walls, a cutting edge. The chip control geometry including a recess defining, when viewed in plan, a generally ''V'' shaped depression having the bottom of the ''V'' proximate the tip of the cutting edge. The extending arms of the ''V'' are distal the cutting edge tip and are crowned by a pair of backramps (50).
