Grinder or polisher for faces stones - has work face on table moved with circular movement superimposed on linear feed

摘要

The machine is mainly for use on large flat stones. The machine consists of two columns (24) on which a slide (30) is mounted. A grinding head carrier can move to and fro on the slide, while the grinding head can move up and down on a vertical guide (26). The workpiece (12) is moved under the traverse on a transport belt (40), while the grinding wheel (28) is moved across the width of the workpiece. The grinding wheel will carry out a linear movement at an angle to the movement of the stone. The traverse (30) is mounted on two eccentrics (34) which are driven synchronously, so that a circular movement is superimposed on the linear movement.
