    摘要： The present invention provides an improved cut-off machine wherein the length of an abrasive wheel in contact with a work is easily adjustable. The cut-off machine of the invention includes: a base with fixed and movable vises for clamping a work; a pair of joint members being supported by a pair of brackets projecting from the rear end of the base so as to pivotably move within a predetermined angle; an arm attached to the upper portion of the joint members; an abrasive wheel mounted on one end of the arm for cutting the work; a handle fixed to the arm for operating the arm; a motor attached to the arm for driving the abrasive wheel; and a compression spring spanned between the base and the arm. The upper mounting position of the compression spring on the arm is closer to the brackets, compared with the lower mounting position of the compression spring on the base. The reciprocating movement of the arm moves the abrasive wheel in the horizontal direction to the current optimal cutting position. Such reciprocating movement efficiently prevents undesirable loading of the abrasive wheel and increases the effective cutting width of the abrasive wheel, thus improving the cutting efficiency.

    摘要： A method and machine (20) for cutting precise sized mults from billets (10) of a nickel based alloy, which involves rotating each billet (10) by means of a chuck (18) while the billet (10) is supported on rollers (12) coaxially in the chuck (18); providing a track (24) parallel to the billet axis (16) and a carrier (22) movable along the track (24), on which carrier (22) is disposed a rotatable saw (54) movable toward and from the axis of the billet (16) to effect cutting, the location of the saw cut being determined by a computer (60) programmed to control a servo motor (58, 56) acting on a screw (57) coupled to the carrier (22) by nut means (22A), the computer (60) being provided not only with basic information as to the density and stated diameter of the billet (10), but with information as to variations in such diameter, detected by sensor means (68) provided on the carrier (22) in proximity with the saw (54), and transmitted to the computer (60).

    摘要： The finding concerns a guide device for a hole saw, comprising a central rod (1), a pair of pins threaded onto said central rod (1) and a plurality of arms (7).
    Said arms (7) being parts of a pair are arranged substantially radially aligned with respect to the central rod (1) and with an X-shaped configuration. A plurality of guide bars (8) of the same number as the plurality of pairs of arms (7) is present, which comprise at least one slot (9), at which the further ends of the pairs of arms (7) are hinged. Said guide device provides that the pair of pins is retained onto said central rod (1) by means of a coupling adapted to allow the variation of their mutual distance, that the plurality of arms (7) is arranged in pairs and finally that one of the ends of an arm (7) that composes the pair is hinged to one of said pins, whereas one of the ends of the other arm (7) is hinged to the other of said pins.
