Abstract

An abrasive saw having an associated cutting wheel is used for cutting objects. The saw includes a base, a cutting assembly operably mounted to the base 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 operably connects the drive shaft and a drive wheel. 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. 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 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 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 to open as a unitary assembly for access to the cutting assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATION DATA[0001]This application is national phase of PCT / US2010 / 029619 filed Apr. 1, 2010, and claims the benefit of priority of Provisional U.S. Patent Application Ser. No. 61 / 174,560, filed May 1, 2009.BACKGROUND OF THE INVENTION[0002]The present invention relates to an abrasive saw. More particularly, the present invention relates to an improved abrasive saw having novel blade and sample drive systems, improved working area / sample access, wear components, and sensor and control features.[0003]Abrasive saws are used in various industries, but in particular are used in the rough or gross preparation of samples / specimens for examination. For example, specimens such as metals or aggregates (concrete) are often microscopically examined to determine grain structure, composition, failures and the like.[0004]In preparing samples, the samples typically must be cut, polished and mounted for examination. The first part of that preparation process, the cutti...
