VESTA-850B provides rigid and stable heavy cutting based on a highly rigid box-way structure and a gear driven high-torque spindle. Cooling of the spindle and frames minimizes thermal displacement to ensure high precision during long-time machining.
Hwacheon software installed on the machine improves productivity and precision, provides better machining quality compared to existing machines.
