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.
|
