Shigiya GPL 30(40) Series

The GPL-30B series has been designed and manufactured according to the latest technological requirements in order to meet the needs of the various customers both in the tool making and in the small-medium production.

Versatility, simple programming thanks to Shigiya’s interactive programming system, Fanuc CNC and the various options available, make the SHIGIYA GPL-30B one of the most effective solutions for both single piece and small to medium batch grinding.

Operator efficiency as well as productivity are further improved, the interactive programming system allows the rapid implementation of both single and multi-diameter grinding programs and automatic in- or out-of-cycle grinding with wheel wear compensation.

GPL 30(40)B is extremely versatile and can be used for both precision machining of single pieces and complex workpieces.

The high-rigidity grinding wheel-holding head is made of high quality cast iron, it houses the hydrodynamic grinding wheel-holding spindle, slides 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.

As an option it is possible to equip the machine with an internal grinding unit to be installed on the grinding wheel head.

The table is supported in its movement by large flat section guides covered with anti-friction PTFE material. Angular adjustment of the table top is possible.

A ball screw activates the movement, it is driven by a servo motor and controlled by an encoder. An optional optical scale can be mounted for position control.

It is equipped with a fixed centre, does not allow any tilting and guarantees instead high rigidity and very low vibrations.
