SIGMA CNC Patent - The spindle ram and Z-axis are designed with 4-linear guideways.
(Roller type guideway, width 45mm) and a box-way construction. During heavy cutting vibrations are eliminated, and during fine cutting inert does not occur, resulting in higher surface accuracy.
All three axes(X, Y, Z) are Roller type linear guideways.
Stronger W-axis (box-way) with Super Column Design
W-axis Standard Stroke 1400mm. (It is possible to be custom-made)
