    摘要： A power saw tool comprises a motor, and a reciprocating mechanism coupled to motor, the reciprocating mechanism being adapted to drive a reciprocating shaft coupled to a saw blade extending from the power saw tool. The power saw tool also includes a housing comprising a body portion and a handle portion, the body portion adapted to house the motor and reciprocating mechanism. A shoe assembly of the power saw tool comprises a shoe having first and second work surfaces on opposite faces thereof. The shoe is arranged for rotational movement with respect to the housing, between a first position in which the first work surface is oriented substantially perpendicular to the saw blade, and a second position in which the second work surface is oriented at an acute angle with respect to the saw blade.

    摘要： A lubrication structure for a working machine is provided that can evenly supply lubricant to a sliding contact surface between an eccentric cam and a crank member regardless of lubricant used and the use environment. A driven gear 12 that engages with a driving gear 11 connected to a driving source and rotates, is accommodated in a chamber 3 in a case 3. An eccentric cam 13 is provided on a surface 12a of the driven gear 12, and connected to a coupling pin 5a in a blade 5 through a crank member 16. A fitting ring part 16b is provided in one end of the crank member 16, and the eccentric cam 13 is inserted into the fitting ring part 16b so as to rotate relative to the fitting ring part 16b. An annular groove 30 is formed on the inner surface of the fitting ring part 16b which faces the outer surface of the eccentric cam 13. The annular groove 30 communicates with a first chamber 33a via a first lubricating passageway 31 and also communicates with a second chamber 33b via a second lubricating passageway 32. The pressure in the first chamber 33a is higher than that is the second chamber 33b.

    摘要： The present invention relates to a stone cutting machine having a wire saw and, more specifically, to a stone cutting machine for cutting stones through vertically-reciprocative swinging. According to the present invention, stone loss due to cutting is minimized such that costs are reduced up to approximately 90%, and sludge is reduced such that work costs (labor costs) and disposal costs are reduced and environmental pollution is prevented.

    摘要： A saw blade (100) has a plurality of teeth (104) with each tooth formed by a beveled leading face (120), a beveled trailing face (122) and a chamfered surface (124) located on the trailing face of each tooth. The trailing (122) and leading (120) faces are beveled in opposite directions in alternate order throughout the saw blade (100) prior to the forming of the chamfered surface (124). The beveled leading face (120) of each tooth intersects the chamfered surface (124) on the trailing face (122) of each tooth to form a curved cutting edge (130) having a negative rake angle. The beveled faces are manufactured by first forming a plurality of rough-formed gullets. The rough-formed gullets are then finished-formed into beveled gullets (110) by a cold-forming operation prior to the grinding of the chamfered surface to form the curved cutting face of the tooth.
