Title:
PORTABLE APPARATUS FOR WORKING, SHAPING AND POLISHING STONE AND OTHER HARD MATERIALS
Document Type and Number:
WIPO Patent Application WO2005056259
Kind Code:
A3
Abstract:
A wheeled trolley carries various tools across an object to be worked. A track attaches directly to the work and simultaneously isolates the tool from the work. A standard connection to the trolley readily accommodates a variety of diverse tools, using a keyway or the like to ensure accurate and repeatable placement of the tools. A preferred contouring guide allows a tool to be moved through an arc, where the focal point of the arc may be set to produce an infinite variety of custom shapes, bevels or angles of cut. An upper stop is provided which readily sets the break line between surface finish and edge contour. An adjustable tool carriage allows control over both position and force, including preloading a work tool with force. Resilience is incorporated into the apparatus to accommodate diverse hardness and abrasion characteristics, and, in at least one embodiment, to enable the track to accurately follow a warped or sagging work piece. Additional supports permit the following of a non-linear edge, and the polishing of arcs and circular objects.
