(54)	Improvements in a machine tool for surface grinding

(57) Improvements in a machine tool for treating the surface of a workpiece (3) using a grinding wheel (2), wherein the machine has a grinding wheel head (1) that is free to move in a radial direction with respect to the workpiece (3) due to the action of irregularities in the shape of the grinding wheel (2) or workpiece (3) and is attached above a guide plate (8). A device (9) keeps the grinding wheel head (1) pressed against the workpiece. Said guide plate (8) is pivoted onto a bench (12) that reciprocates along the workpiece (3) and can swing about a vertical axis (X-X) that passes through the central plane (M) of the grinding wheel (2) and the line (S) where the grinding wheel (2) makes contact with the workpiece (3) when the axis about which the grinding wheel and workpiece rotate are not parallel.
