HOB & TAP GRINDING MACHINES

RFM Series

The main characteristics are the following:

  • High dynamics relieving by means of linear motor technology.
  • Built-in spindle motors.
  • Wide range of wheelhead configurations for specific component requirements: cylindrical wheel, cup-form wheel or finger wheel.
  • Helix angle by means of power motor (+90º / -225º)
  • Software :
    • Wheel profile definition through standard parametric program or external *.dxf file.
    • Grinding tool is calculated and optimizedin relation to the hob defining parameters – diameter, num. of flutes, lead angle, relief depth, ….
  • Grinding accuracy AAA according to DIN 3968.
