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
SIGMA CNC Patent – Y-axis configured by 3-linear guideways (Roller type guideway, width 65mm) for horizontal and vertical directions that offer greater stability and rigidity for the machine
All three axes(X, Y, Z) are Roller type linear guideways
