<p>PURPOSE: A circular saw cutting machine is provided to promote reduction of the manufacturing cost by applying hydraulic cylinders to an opening and shutting drive unit of a main vice mechanism and a transfer drive unit of an object-transferring vice mechanism and executing the opening action of the main vice mechanism and spread action of the object-transferring vice mechanism by a hydraulic sequence circuit. CONSTITUTION: A circular saw cutting machine has a main vice mechanism and an object-transferring vice mechanism(15). The circular saw cutting machine comprises an oscillation lever(23) with a stopper(25) regulating a usual retreat position(Q1) of the object-transferring vice mechanism at one end of an oscillation point(24); a spring(26) supporting the end of the other side of the oscillation lever; and a spread hydraulic cylinder(28) oscillating the stopper in the retreat direction of the object-transferring vice mechanism. A main vice-opening operation side chamber of a main vice-opening and shutting hydraulic cylinder(14) and a lever-pressing operation side chamber of the spread hydraulic cylinder are connected to a first pipe line. A second pipe line branching off the first pipe line and a third pipe line connected to a main vice-discontinuing operation side chamber of the main vice-opening and shutting hydraulic cylinder are connected to a hydraulic source and to a tank through a switching valve.</p> |
