MINERAL CAST VERTICAL MACHINING CENTER

Stability, built into the structure.

StableTech mineral casting combines high vibration damping and thermal inertia to protect accuracy, surface finish and productivity during continuous high-speed machining.

01 / Engineering Advantage

Not simply heavier.
Inherently more stable.

Mineral casting controls vibration through material damping and resists thermal drift through high inertia—creating a more stable geometric foundation under dynamic loads.

StableTech®

Mineral casting controls vibration through material damping and resists thermal drift through high inertia—creating a more stable geometric foundation under dynamic loads.

15×

Vibration absorption

More than 15 times the damping of cast iron helps reduce abnormal impact between tool and workpiece.

StableTech
16×

Thermal inertia

High thermal inertia limits structural deformation caused by changing ambient temperatures.

StableTech
23%

Lower tool wear

Reduced micro-vibration extends tool life and supports a more consistent surface finish.

02 / Product Range

From compact precision
to large-travel cutting.

Five CTL models cover X-axis travels from 600 to 1500 mm, with spindle packages for high-speed finishing or heavier cutting.
