IMPROVED ABRASIVE SAW

摘要

An abrasive saw (10) having an associated cutting wheel (W) is used for cutting objects. The saw includes a base (12), a cutting assembly operably mounted to the base (12) and a controller. The cutting assembly includes a pivot shaft, a drive shaft operably mounted to the pivot shaft, a drive, and a drive wheel. A flexible drive element (34) operably connects the drive shaft and a drive wheel (36). The distance between the drive wheel axis of rotation and the drive shaft axis of rotation is variable to increase or decrease a tension in the flexible drive element (34). A feed table is operably mounted to the base and is movable forward and rearward in a direction of rotation of the associated cutting wheel. The cutting wheel (W) is lockable in the cutting position and the feed table, with the object secured thereto, is moved, by the controller toward the associated cutting wheel (W) to cut the object. An enclosure encloses the cutting assembly and has stationary sides and openable front and top panels hingedly mounted to one another and to a portion of one of the side panels (20, 12D) to open as a unitary assembly for access to the cutting assembly.
