RAPID 1000

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 1000 for workpiece diameters of up to 1,000 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.

  • Highly flexible direct-drive 5-axis grinding head and swivel angle adjustment during the grinding process
  • Stable, damping-optimized single-bed base made of cast polymer
  • Precise machine table control via torque motor drive
  • Optional internal gear grinding arms
  • Controlled grinding result thanks to integrated measurements and automatic corrections during the grinding process
  • Energy efficiency (e2)
