A power assisted drill press having a feed cylinder fed by a variable pressure regulator which allows a user to controllably feed a bit and work material together while activating a drill motor to rotate the bit. An embodiment of the power assisted drill press utilizes a suction cup and venturi system for attachment of the press to a surface work material. The drill press uniquely allows a person to variably activate the feed cylinder and also activate the drill motor with a single hand.

Various embodiments include a rotor having a dovetail slot with a bulbous fillet region, and in some cases, recessed inclined bearing surfaces. Various embodiments include methods of forming such a slot in a turbomachine rotor.

An insert for a drill in which one of the cutting edges respectively formed at four side ridge portions of a rake face of a square flat plate-shaped insert body is made to protrude toward the tip of the drill body of the indexable insert drill while being detachably attached is provided. Each of the cutting edges has a corner cutting edge located at a corner of the rake face, and a major cutting edge and a wiper edge which extend substantially toward one peripheral direction of the rake face from a corner cutting edge. The major cutting edge has a first major cutting edge portion which has a convexly curved shape and extends from the corner cutting edge, and a second major cutting edge portion which smoothly touches the first major cutting edge portion and extends linearly, as seen from a direction facing the rake face. The wiper edge has a straight shape intersecting the second major cutting edge portion at an obtuse angle.

Apparatus (25, 25') for removing burrs (22) on billets (20) characterized in that it comprises: - a supporting element (26, 26'), - at least two arms (28, 30, 28', 30') extending from said supporting element (26,26'), - deburring means (24, 34, 24', 34') able to be driven in rotation by burrs (22) of billets (20), the deburring means (24,34,24',34') being supported by the arms (28,30,28',30'), - driving means (35) for driving rotatably and reversibly the apparatus (25,25') between a stand-by position wherein the apparatus (25,25') is spaced apart from the billet (20) to be deburred and a working position wherein the deburring means (24,34,24',34') are close to the billet (20) to be deburred and are able to contact a burr (22).

Various embodiments include a rotor having a dovetail slot with a bulbous fillet region, and in some cases, recessed inclined bearing surfaces. Various embodiments include methods of forming such a slot in a turbomachine rotor.

A method for machining a workpiece which can prevent a reduction in machining accuracy and production efficiency. The method includes pressing a clamp part against a first portion of the workpiece, to clamp the workpiece in cooperation with a workpiece receiving part, causing the clamp part to move away from the first portion, to release the workpiece, which has been clamped by the clamp part, operating a robot to cause a robot hand to grasp a second portion of the workpiece, which is different from the first portion, to restrict the movement of the workpiece relative to the workpiece receiving part without a change in the posture of the workpiece, and operating a machine tool to machine the first portion while restricting the movement of the workpiece relative to the workpiece receiving part.

The invention discloses a tool capable of press fitting multiple parts simultaneously. The tool is characterized in that a tool plate and a bottom plate form a frame structure through four guide pillars; a movable plate is installed between the tool plate and the bottom plate, the movable plate is driven by a screw rod and is guided by the four guide pillars; a screw hole is formed in the centre of the movable plate, the thread end of the screw rod is installed in the screw hole, the other end of the screw rod is a step shaft, and the step shaft is installed in a circular hole formed in the center of the tool plate through a screw rod end cover and a bolt; a plurality of step holes are formed in the tool plate, each step hole is provided with a hexagonal locating pin with a through hole in the center, a compressing shaft penetrates through the central through holes of the hexagonal locating pins in a free fit mode and is in clearance fit with a plurality of through holes which are correspondent one to one in the movable plate, and the compressing shaft is installed on the movable plate through an elastic element and a nut; a limit bolt is installed on the base plate and plays the role of limiting position; the compressing shaft compresses parts through a pressing plate. The tool has the advantaged that multiple parts to be machined can be press fitted at one time, and the production efficiency is high.

Disclosed is a machine tool comprising: a base having a mounting space in which a workpiece is mounted, shaft holes formed in opposite wall surfaces thereof, and a pair of first shaft sliding parts facing each other on opposite sides of the mounting space; a saddle coupled to the first shaft sliding parts of the base so as to slide on a first shaft and having a pair of second shaft sliding parts facing each other in a direction intersecting the first shaft; a crosspiece coupled to the second shaft sliding parts of the saddle so as to slide on a second shaft and having a pair of third sliding parts facing each other in a direction perpendicular to a plane on which the first shaft and the second shaft are formed; a vertical ram coupled to the third shaft sliding parts of the crosspieces so as to slide in a direction perpendicular to a plane defined by the first shaft and the second shaft and having a tool for machining the workpiece mounted at an end thereof; and a table disposed in themounting space of the base and installed on the base so as to be rotatable relative to the base through shaft holes of the base.

The invention relates to a large aluminum piece milling and positioning clamp which comprises a plurality of first positioning blocks, a plurality of second positioning blocks and a plurality of third positioning blocks. The first positioning blocks, the second positioning blocks and the third positioning blocks are arranged side by side and provided with first steps, wherein the first steps are provided with kidney-shaped holes.
