Starrag claims its Heckert machine is the “most thermally-stable machining centre in the world”

A positioning accuracy of just four microns in linear axes and only four secs of arc in the NC rotary table – compared to six microns and six secs of arc on conventional machining centres - applies to the four-machine Heckert HEC 1000/1250/1600/1800 models. The machines boast X, Y and Z axes travels from 1,700mm by 1,250mm by 1,850mm (on the HEC 1000) up to 3,400mm by 2,800mm by 2,250mm (HEC 1800).

The use of an innovative ‘jacket’ creates a machine base that is thermally insulated against ambient temperatures and internal heat sources, and a temperature control system guarantees to keep all structural components at a constant temperature to eliminate the chance of fluctuations between foundation and machine base and bed.

In addition, the granite bed offers similar static and dynamic properties as a steel version, but no thermal disadvantages – it has a 50% lower co-efficient of linear expansion - nor magnetic or corrosion issues.
