GER spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of spindles and motor spindles on GER grinders. GER is a Spanish manufacturer of surface, cylindrical and rotary table grinders, founded in 1952 and strongly export-oriented.
GER, a Spanish builder of precision grinders
TLDR: GER Máquinas Herramienta (Spain) has built precision grinders since 1952: surface and profile grinders, internal cylindrical grinders, rotary table grinders and universal grinding centres. Around 90% of its output is exported.
GER offers several families of CNC grinders: internal cylindrical grinders, surface and profile grinders, rotary table grinders with horizontal or vertical spindle, and universal rotary table grinding centres. They serve aerospace, automotive, bearings, gears, plastic injection and oil and gas. GER machines are widely found on the used market, including surface grinders built under ELB licence (RSA 650 model): see also our page on ELB Schliff.
In March 2022, GER introduced a new range of heavy fixed-workpiece cylindrical grinders, with longitudinal and transverse wheelheads, for workpieces of 4 m and more, up to 10 m long and 10 tonnes. It takes up 35% less floor space than the previous range. One customer chose it to grind injection and extrusion screws up to 5 m long.
Wheel spindles from 9 to 30 kW
TLDR: On GER surface grinders, the wheel spindle delivers 9 to 22 kW (up to 30 kW depending on configuration) with wheels from 400 to 500 mm in diameter, according to the manufacturer's catalogue.
GER catalogue data for the SR and SR CNC series give the following wheel spindle ratings: 9 kW on the SR 50 and SR 60, 11 kW on the SR 70 and SR 80, 22 kW on the SR 90 and SR 100, with 15 or 30 kW depending on configuration. Wheels range from 400 × 100 × 127 mm to 500 × 100 × 203 mm. The smaller SC and SCA surface grinders use wheels from 225 × 25 × 51 to 400 × 50 × 127 mm.
A 1988 RHC-1200 cylindrical grinder is listed with 1,200 mm between centres, a 400 × 50-80 × 127 mm wheel and an 8 kW drive. The catalogue gives neither the speeds nor the bearings of the GER spindle: we confirm them in our quote.
