Abstract

A grinding machine (1) that comprises two aligned columns (2,3), each of said columns (2,3) being provided with one wheelhead (4,5) with its respective grinding wheels (6,7). The columns (2,3) slide over a base (9) common to both and parallel to at least one machining table (11), each of the wheelheads (4,5) has its own vertical drive system and its own transverse drive system and both grinding wheels (6,7) may work simultaneously.

Claims

1. A grinding machine for grinding bulky workpieces of considerable length, such as frames, columns, tables, etc., which comprises:

at least one machining table on which the workpiece to be ground is placed,

at least two columns linked at the bottom to a carriage, which slides longitudinally over a base parallel to said machining table;

at least one wheelhead with its respective grinding wheel on each one of said columns, at least one of said wheelheads being capable of angle movement;

in such a way that the vertical and transverse drives of the wheelheads of each column are independent of each other and said wheelheads, therefore, are able to work simultaneously.

2. A grinding machine according to

claim 1

, wherein said columns are facing each other.

3. A grinding machine according to

claim 1

, wherein the movement of said carriage over the base is effected by means of a hydrostatic slideway.

4. A grinding machine according to

claim 1

, wherein the longitudinal movement of the carriage is governed by means of a rack and pinion and encoder system.
