millGrind
Multiple Technology Solution in one Set-Up

The millGrind series is specially developed for the requirements of machining in the turbine industry as multiple technology solution in one set-up. The modular machine system in travelling table design allows an individual configuration of the machine according to the customers needs.

Automatic tool and diamond roll changing allows the machining via

  • Grinding, Al-Oxide, CBN and Diamond Grinding Wheels
  • Boring
  • Milling
  • Laser Cladding
  • Measuring of the unfinished workpiece
  • Measuring of the machine workpiece including rework

in one set-up. This guarantees that all machined surfaces run to each other
and errors are avoided by repeated re-chucking.

Benefit Overview

  • Multiple Technology Solution in one Set-Up 
  • Automatic Tool and Diamond Roll 
  • Quick Change Over Time 
  • High Stock Removal Rate due to Continuous Dressing Capability 
  • Good Cost-Performance Ratio 
  • 2- or 3-Axes Rotary Tilt Tables as Option 
  • Automatic Workpiece Changing as Option

In addition to the machining of new blades and vanes for rework a laser cladding device can be added. This allows the measuring, cladding and grinding or milling of the worn areas.

For grinding with high stock removal rates the grinding wheels can be sharpened via overhead dressing unit and intermittent or continuous dressing. For pilot production or small lot sizes a table mounted dressing unit with interpolated dressing via vertical and cross feed axis can be used.

The tools will be exchanged automatically out of a magazine with 12/24 storage positions.

In combination with a 2 or 3 axes rotary tilt table mounted on the machine table a multiple sided machining is possible. The multiple axes interpolated machining of complex profi les will be achieved due to the sophisticated CNC control Siemens 840D.

For almost all applications proven Elb cycles are already written. For each machining application a team of experienced application engineers and programmers are available.
