A horizontal bandsaw has a main vise positioned slightly to the rear of the cutting location for gripping the workpiece during cutting, a material feed vise positioned to the rear of the main vise for feeding material into the cutting location, and a front vise positioned to the front of the cutting location. The front vise can move to a position to the rear of the cutting location to retrieve a small remnant of uncut material. The three vises each have a movable and a fixed jaw. A lower limit guide is provided on the main vise movable jaw which adjusts the descent of the cutting tool to the width of the workpiece. The fixed jaws are provided with means located within the operating area of the jaws for a slight advance or retraction of the contact face, to firmly grip the workpiece or to retract the contact face so as to prevent frictional contact with the workpiece. The movable jaws have a hydraulic cylinder built into a sliding tube for providing reciprocating motion. A moving position detection device is mounted on the material feed vise for determining the extent of longitudinal motion of the material feed vise so that the material feed vise can be positioned at a presecribed position. A laser beam head is mounted on the cutting head to verify accuracy of positioning of the workpiece. A rotating brush device has an easy mounting and dismounting construction. |
