RAPID 2500

HÖFLER Cylindrical Gear Grinding Machine


Giant with absolute precision, speed, and flexibility

The RAPID 2500 cylindrical gear grinding machine is the specialist for large, heavy workpieces up to 2,500 mm in diameter and weighing up to 25 tons. These giants combine maximum dimensions with absolute precision, speed, and flexibility: Topologically correct results with reduced grinding times and an optional internal grinding device form the basis for economical, reliable cylindrical gear production on this scale. In combination with the cutting machines, RAPID machines in the cylindrical gear technology division provide an ideal system for the cylindrical gear production 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)
