The MIKRON HPM machine design concept from the business management point of view

With the MIKRON HPM 600 HD, customers can call on integrated automation solutions for cell production, or overlapping automation solutions for multi-process production, for an effective reduction in downtime.

When designing the machine, particular attention was paid to highly dynamic feed drives, rigid machine components and state-of-the-art spindle technology for a reduction in machining time.

For many customers, precision microfinishing of the surfaces of hollow molds is one the most important performance characteristics that the MIKRON HPM 600/900/1200 HD series has to provide. In this respect, the machine enables a simple process control, since the polymer base only reacts very sluggishly to changes in temperature.

Any minor geometrical deviations that occur can be compensated for in the control system. In this connection, a great deal of development work has gone into the smart machine module ITC (Intelligent Thermal Control) from GF AgieCharmilles. Lowvibration movement control of the three linear axes was also achieved by means of a heavy machine base of polymer concrete with a dead weight of 5,700kg.

The 3-axis HPM machining center not only provides high-performance, quick and accurate machining, but also suggests itself for workpiece automation with pallet magazines tailored to the machine or through the adaptation of a universally useable industrial robot. Unused machining capacities can be exploited and unit costs reduced in the long term with a custom-design automation solution. Palletized automation solutions allow non-operative times after rough machining, which are required in the precision machining of aluminium without productive machining times having to be sacrificed. The MIKRON HPM 600 HD also offers the requisite modular design in order to be able to join the world of automation at a later date.

Vector-regulated motor spindles of the subsidiary "Step-Tec" are used to meet machining requirements. They can either be operated at speeds of up to 15,000rpm or 20,000rpm, and have a peak torque of 84Nm in the lower speed range - sufficient power for high removal rates in aluminium or steel. The continuous oil/air lubrication of the ceramic hybrid bearings permits a long operating life of the spindle and drive module. If an exchange becomes necessary, this service need is quickly resolved.
