Shigiya LPG 20-50 Series

One of the most successful series for the production of small to medium sized components for cars, motorbikes and hydraulic components.

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. The grinding wheel will not start if there is no confirmation of oil circulation in the bearings.

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.

The travel speed is adjustable up to a maximum of 15 m/min.

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