Largest profile surface grinder from GER

International Manufacturing Solutions Ltd (IMSL), the UK agent for GER, has announced the launch of the GER SR 400-100 CNC plane and profile surface grinder. Although the 4 m grinder is currently the largest profile surface grinder manufactured by GER, if required, the company is able to produce machines with capacities of up to 6 m.

The 4000 x 1000 mm capacity machine was initially developed for an Austrian manufacturer of press tools, and is equipped with a 500 mm diameter x 100 mm wide wheel head incorporating a 30 kW spindle motor and three independent rotary diamond dressers. All slideways incorporate precision ball screws, Fanuc drive motors and Heidenhain linear scales. Control is via Fanuc 0i-TD.
GER’s SR 400-100 has a vertical distance (table to wheel spindle centre) of 1000 mm and a maximum component weight capacity of 4300 kg. Perlite cast iron is used for all of the machine’s major castings, which are ribbed and feature box-section construction.
The machine’s X-axis table guideways are mounted directly to the front section of the bed, enabling the table to accept much heavier loads while still achieving smooth movement at high speeds, says GER; a design principle that also applies to the machine’s Z-axis column guideways.
A motor assembly mounted inside a heavy cast casing within the column structure is a feature of the machine’s wheel head. This heavy-duty assembly balances the generated masses and, as it is mounted at the rear of the guideways, limits wheel head overhang to avoid deflections under demanding grinding conditions.
