Corvus NGB BPP

Corvus NGB grinding machine

DESCRIPTION

 

corvus NGB BPP

The 6-axis CNC profile grinding machine for the production of profiles on broach tools or the profiling of automotive body panel dies.

The 6-axis CNC grinding machine corvus BPP has a highly dynamic linear motor driven vertical oscillating axis. The corvus BPP represents the solution for all profiling tasks in which the grinding wheel must oscillate in a vertical direction. The zero points on the tools are found automatically by the high-precision 3D probe.

Applications for the corvus BPP are the regrinding of automotive body panel dies with torus radius wheels using oscillating grinding approach as well as the profiling of broach tools.

Accessories for individual expansion of the application spectrum and for increased productivity:

  • X-stroke of 1250 mm up to optional 3100 mm
  • Direct measurement system in all axes
  • Linear motors in all axes
  • Direct drive motor for cylindrical grinding tasks up to 1250 Nm torque
  • Dressing unit for dressing and sharpening profiles
  • Manual or hydraulic tailstock
  • Manual or hydraulic steady rest
  • Magnetic chuck
  • Collet chucks, clamping mandrels
  • Coolant filtration system
  • Exhaust air filter
  • CO2 extinguishing system

 

 

Applications for the CORVUS bpp are regrinding car body cutting blades using torus discs in oscillation grinding and profiling broaches of all types and sizes.
