Abstract

The hydraulic drive of a reciprocating workpiece table (2) of a surface grinding machine comprises a pump (4) a double-acting hydraulic cylinder (3) and valves contained in the lines between pump and cylinder and the table. The stroke of the table (2) relative to the machine bed centre is controllable by means of two potentiometer-adjusted timing circuits (22) which are alternately activated by a non-contact centre point switch (11) arranged at the machine bed centre, as the table slides by. The circuits, upon lapse of set time reverse the hydraulic drive via an electromagnetically operated 4/2-way valve (9). A logic device (24) varies the timings of the circuits (22) in accordance with table speed, which is controlled by a servomotor (13) acting on a choke valve (12).
