MACHINE BASE & GUIDEWAYS

The machine base is made from a mineral casting or grey cast iron optimized for high rigidity, vibration damping and granting longer wheel life and better surface finish.

Temperature fluctuations are extensively compensated by the favourable thermal behaviour of the machine base, resulting in high dimensional accuracy at all time.
