RAPID 1250

HÖFLER Cylindrical Gear Grinding Machine

Reduced grinding times for more production efficiency

Cylindrical gear manufacturers all around the world appreciate the advantages and productivity of the RAPID 1250 for workpiece diameters of up to 1,250 mm. With standard features that include a cast polymer machine bed, a torque motor-driven machine table, an integrated inspection system, a sturdy grinding spindle, and a dressing system for frequent profile modifications, it is the perfect solution for cylindrical gear manufacturers. Technologies such as high-speed grinding [HsG] and best-fit grinding [BfG] also reduce grinding times by up to 30 % ensuring a clear leading edge in production efficiency for the entire manufacturing process.
