Abstract
Abstract Apparatus for grinding or polishing or glazing or otherwise finishing flat or contoured-in-one dimension surfaces of a work as the work is held on a work table reciprocated rectilinearly along a horizontal plane in front-rear and end-end directions with reference to a tool mechanism in the form of a driven rotatable grinding or polishing or glazing wheel having a peripheral face providing the grinding or polishing or glazing action, with cooperant means for reciprocating the work table in the forward and rearward directions and simultaneously therewith in the end to end directions, and other means for simultaneously driving the tool mechanism vertically to bring the tool into and remove the tool out of working position with respect to work.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
In a machine tool for grinding or polishing or glazing a flat or contoured-in-one-dimension surface of a workpiece, the combination of: a support structure, a main slide assembly being alternatingly reciprocatable in a horizontal plane between the forward and rearward sides of the support structure, means for alternately reciprocating the main slide assembly, a workpiece supporting table assembly mounted on the main slide assembly and being alternatingly reciprocatable in a horizontal plane between the ends of the support structure, means for alternatingly reciprocating the table assembly, means for holding the workpiece upon the table assembly, tool supporting means at each opposite end of the support structure, a tool rotatable mounted upon the tool supporting means on an axis transverse to the direction of movement of the main slide assembly and disposed in a horizontal plane above the plane of the table assembly and having a peripheral face movable into workpiece engaging position relative to the workpiece, means for driving the tool, and cooperating cam means on the main slide assembly and the tool supporting means for vertically motivating the tool toward and away from the workpiece according to the contour of the surface thereof to be operated upon the tool.
