This GER RSA 750 is a surface grinding machine — sometimes referred to as a flat grinder — designed to produce precise, flat finishes on metal workpieces through the controlled action of a rotating abrasive wheel against a reciprocating table. GER is a Spanish manufacturer with a long-standing reputation for building precision surface and cylindrical grinding equipment used across toolmaking, metalworking, and general engineering industries.
The machine is equipped with an electromagnetic chuck measuring 750 × 300 mm, which secures ferromagnetic workpieces firmly and evenly during the grinding cycle. Maximum grinding capacity is 750 mm in length, 500 mm in width, and 425 mm in height, giving the machine a broad working envelope suitable for medium to large flat components. The grinding wheel measures 400 × 80 mm and runs at a spindle speed of 1,500 rpm.
Table travel speed is variable between 2 and 20 m/min, allowing the operator to tailor the feed rate to the material and surface finish required. Crossfeed is handled electrically at a rate of 1.20 m/min, while intermittent crossfeed can be set anywhere in the range of 2 to 60 m/min, providing flexibility for both fine finishing and more aggressive stock removal passes. The overall table surface measures 750 × 500 mm.
The machine weighs 3,500 kg, reflecting the robust cast construction typical of precision surface grinders of this class. Two units are available from stock, located in Portugal, and both are offered in used condition. The listing year is 2001, and each unit is priced at $12,500.
