BENEFITS

  • Quick and easy setups due to innovative tooling as well as the automatic wheel changer and optimized accessibility to work area.
  • High grinding performance covering a wide range of cutting tool applications based on a powerful grinding spindle.
  • Direct drives on each axes combined with direct measuring systems provide continuous highest accuracy. The smart designed cast-iron base reaches thermal stability after very short warm up times.
  • Rigid and vibration dampening machine base results in smooth surface finish and minimized wheel-wear.
  • Cost effective re-sharpening now possible due to our unique probing routines based on NUMROTOplus®. This user-friendly programming interface manages a wide variety of geometries and reduces the risk of collisions to zero.

SMART KINEMATICS

Everything is within easy reach considering the generously proportioned working area. This is the result of a carefully engineered machine design.

AUTONOMY AND PRODUCTIVITY

Two systems working hand in hand, efficient even for small batch production and mixed diameter ranges. Automated production and reliability is provided by the simple pick-up loader. Based on the same principle, the wheel-changer located outside of the working area makes sure the HSK63F stays clean and is accessible even when the machine is in operation.

THE RIGHT FIXTURE FOR EACH SITUATION

Universally exchangeable, always the right support for your applications:

  • Automatically retractable V-block.
  • Manually adjustable V-prism.
  • Tailstock.
  • Run-out optimizing system.

CHECKING INSTEAD OF BELIEVING

Tool or wheel accuracy monitored by in-process measuring processes as well as the automatic tool or blank referencing after a new setup are easily accomplished using the available probes and probing routines.

WITH THE OPERATOR IN MIND

Access from 3 sides and wide open view of the grinding process, enhances operational safety. Optimized ergonomics provided by the height adjustable and 90° rotation-able control unit guarantees outstanding working comfort.

NEVER ALONE FACING TODAY‘S CHALLENGES

Complex tools require sophisticated grinding strategies. Our experts can support you:

  • Remote diagnostics.
  • Programming support.
  • Customer specific grinding tests.
