Shigiya GSU-30(40) B Series

Quality and performance without compromise.

GSU-30B has been designed and manufactured according to the latest technological requirements in order to meet the production needs of customers.

The versatility, the ease of programming thanks to the Shigiya interactive system and the Fanuc CNC, make the GSU-30B one of the most effective solutions for both single workpiece and small to medium batch grinding, an easy-to-use tool designed according to the operator’s needs.

The high-rigidity grinding wheel head is made of the highest quality cast iron and houses the hydrodynamic grinding wheel spindle.

Nine configurations of the grinding wheel head are possible. In the standard configuration, the grinding wheel head moves on a flat guideway coated with anti-friction PTFE material to ensure small increments and high rigidity.

The axial movement is activated by a ball screw, combined with a servo motor and the axis position is controlled by an optical scale.

The spindle bearing lubrication unit, which is separate from the rest of the machine, prevents heat loss in the head due to increased oil temperature.

The traverse speed is adjustable up to a maximum of 10 m/min while the minimum programmable increment is 0.001 mm.

The machine has a fixed centre and does not allow tilting. High rigidity and low vibration are its strengths.

The rotation speed is selectable from 15 to 600 rpm.
