Overview

Compact bridge-type precision VMC, 600 / 450 / 350 mm at 15,000 rpm

The U1 is a compact vertical machining center with a bridge-type structure, built for precision machining; Hwacheon's lineup lists it under ceramic machining. Travels are 600 / 450 / 350 mm over a 700 x 450 mm table rated for 500 kgf, with 900 mm between the columns. The built-in BBT-40 spindle runs to 15,000 rpm at 18.5/15 kW with air-oil lubrication and jacket cooling, fed by a 20-tool magazine. The control is a FANUC 0i-MF Plus, and the machine weighs 6,500 kg.
