Full of Features

Toyoda’s progressive filtration system for coolant through spindle prevents clogging and reduces thermal expansion, while high-quality THK roller guides provide stability without sacrificing speed.

Heavy Cutting Capabilities

A Meehanite cast iron base and dual bridge columns provide excellent vibration dampening during large-part machining for rigid, precise cuts.
