Overview

Advantages
Based on decades of experience and exemplary know-how, Waldrich Siegen has revolutionized its successful milling machine concept. The result is a portal milling machine line setting standards in the market with regard to precision and performance.

Outstanding performance
There was a particular focus on significantly increasing performance and torque compared to the concepts already available on the market, as well as on increasing the operational availability. By means of easy maintenance and service as well as energy efficiency, the economic viability of the machine could be considerably increased and life cycle costs were minimized.

The ProfiMill covers a complete application range with its modular design:
With a fixed or movable cross rail

• In gantry design
• In table design
• In twin-table design
• As a pallet design

Key Benefits

Machine technology

• Masterhead Concept – up to 140 kW
  Waldrich Siegen has further developed the Masterhead concept for machines with the highest power and torque. As a result, the spindle is reduced to a simple drive shaft. All milling attachments are adapted through the Masterhead interface. A universal milling head with exchangeable motor spindle allows for almost all required spindle speeds. Therefore, a large number of milling attachments can be equipped with life-time grease lubrication. Additional susceptible cooling circuits are no longer required. Another positive effect on machine availability and maintenance cost is achieved by the reduced number of media transfers at the interface. The Masterhead interface is provided with four self-locking, clamping elements with a high clamping power at relatively low hydraulic pressure.

• Hydrostatic guideways and drives
  Waldrich Siegen has further developed hydrostatic worm drives and guideways for ProfiMill heavy-duty cutting processes and extremely improved the dynamic stiffness of the hydrostatic worm racks. In order to achieve the highest stiffness combined with unsurpassed clamping characteristics, all machine axes are hydrostatically guided. Up to 4 individual hydrostatic guideways with pump per pocket system on machines in table design allow for workpiece weights of up to 500 tons and more. The portals of the gantry machines are also hydrostatically guided and in case of very large portals even hydrostatically driven. The Y-axis (saddle on cross rail) is driven by an electrically pre-loaded master/slave drive on all machines in order to assure the highest positioning accuracy and feeding forces.

• Controls
  The ProfiMill is available with a Siemens 840D sl control or, optionally, with a Fanuc or Heidenhain control. The machines are equipped with the Siemens-Sinamics drive concept, fitting the Siemens control. Digital interfaces with "Drive Cliq" function allow for easy configuration.
