Overview
Accuracy where temperatures change
INVAR extends the PARPAS range of travelling column machines. Its name refers to its main design goal: accuracy in environments where the temperature changes. The main components were designed with FEM structural analysis plus static, dynamic and thermal analysis.
The design targets structural rigidity, chip removal rate, volumetric accuracy, dynamic performance, operational safety and ergonomic operation. The working area takes a range of heads shown on the official page.
The longitudinal axis runs from 6,000 to 30,000 mm, the cross axis is 1,250 + 1,000 mm or 1,500 + 1,250 mm, and the vertical axis runs from 3,000 to 6,500 mm. Feeds reach 25,000 mm/min, and the spindle offers 107 to 134 kW and 3,000 rpm with HSK-63A, HSK-100A, ISO40 or ISO50 taper.
