Production HMCs have high dynamics

Extremely high dynamic characteristics, with accelerations of up to 12 m/sec2 and rapid traverse rates of 60 or rather 90m/min of a horizontal machining centre, guarantee short machining times.

Horizontal machining centre MCi 25.1 - reliable and dynamic with an excellent cost-benefit ratio Machines from Heller's MCi range are successfully used throughout almost all industries.

The machines' extremely high dynamic characteristics, with accelerations of up to 12 m/sec2 and rapid traverse rates of 60 or rather 90m/min, guarantee short machining times - an important factor to reduce per-piece costs.

The high dynamics of the MCi series are excellently suited for the machining of light and non-ferrous metals.

Thanks to application of state-of-the-art control and drive technology positioning and path accuracy were improved once more.

The optional Dynamics Package to be presented at the METAV 2006 provides more than cycle time savings.

Chip-to-chip-time is a major factor in cycle time.

Dynamics Package 1 provides a chip-to-chip time of only 3.0s - one of the best in its class.

The horizontal design of the MCi series also holds many advantages for the machining of grey cast iron or hardened steel.

A robust, inherently rigid T-shaped bed and a gantry column from nodular cast iron with optimised structure and thermosymmetrically mounted spindle unit provide the necessary rigidity.

In addition, pre-loaded roller elements, zero backlash guideways and direct path measuring systems ensure maximum machining accuracy.

The special technical characteristics of the MCi 25.1 exhibited at the Heller booth D35 in hall 15 are ideal to boost flexibility in single-part or low-volume production.

A rotary feed table with a resolution of 360,000 x 0.001 deg and the additional 5th axis extend the machining options and allow five-sided machining in one set-up.

A high-speed chain magazine with 80 tool places and an additional operator panel at the tool setting station allow loading of tools during the ongoing machining cycle.

An infrared receiver located inside the work area and a Renishaw measuring probe help to monitor machining quality and considerably contribute to high process stability in unmanned operation.

For the machining of sculptured surfaces Heller offers a special mould and die package.

This includes a powerful computer, simultaneous interpolation of axes, short block cycle times and high-speed processing with look ahead function.

Even a higher chip-removal rate is no great challenge for the machine: steep chip slopes in combination with efficient work area flushing and a wide chip conveyor ensure reliable chip disposal at any time.
