摘要:
An apparatus for machining metal workpieces has a frame defining machining, pick-up, and drop-off stations. A vertical slide is vertically shiftable on the machine frame. In turn a horizontal slide carrying a rotatably driven holder is horizontally shiftable on the vertical slide between respective pick-up, machining, and drop-off positions above the stations. A holder is provided in the machining station, and one of the holders is adapted to hold a tool and the other of the holders for holding a workpiece for machining the workpiece in the machining station. A pair of shields is fixed to the vertical slide and horizontally flanks the machining station. One of the shields is between the machining station and the pick-up station. Respective slidable doors on each of the shields are shiftable between a closed position blocking movement of the rotatable holder past the respective shield and an open position permitting such movement.

A machine tool includes: a bed, the upper surface of which has the table provided thereon; a cut debris duct which is provided so as to extend rearward from a cut debris discharge opening open at the center, in the left-right direction, of the rear face of the bed, and which discharges cut debris from within the bed to outside of the machine tool; a bifurcated vertically movable body which vertically moves along a pair of vertical guides, and which straddles the cut debris duct, the pair of vertical guides vertically extending on the rear face of the bed at positions on both the left and right sides of the cut debris duct; and a pair of left and right feed screws which extend parallel to the vertical guides, and which move the vertically movable body along the vertical guides.

A end mill includes: an end mill body having a rotation axis, the end mill body including a shank portion and a cutting portion with an outer peripheral cutting edge; an end cutting edge including a first cutting edge and a second cutting edge; a first gash opening between the first cutting edge and the second cutting edge; and a second gash located adjacently to the first gash in the rotational direction, and opening to a side closer to the outside peripheral from the chisel portion. A ratio (L1/L2) of a length (L1) from a distal end of the end mill body to a terminal end of the first gash to a length (L2) from the distal end of the end mill body to a terminal end of the second gash, when viewed from a side, is from 0.8 to 1.1.

A face milling tool includes a body which is rotatable about an axis, at least one wiper tooth, and at least two primary cutting teeth mounted on the body having a cutting edge for cutting about the axis. The primary cutting teeth are staggered radially relative to each other by a radial shift so that a chip load variation during operation is less than 0.7 times a mean primary-tooth chip load. A method for determining the primary cutting tooth radial positions on a face milling tool body is provided such that a chip load variation during operation is less than 0.7 times a mean primary-tooth chip load.
