The Bridgecenter-8G #40 is a double column, 3-axis vertical machining center built on a Meehanite cast iron bed with square-section support columns and a triangular cross beam. It has a 900 x 2500 mm table, travels of 2032 x 1095 x 710 mm in X, Y and Z, and a 20-20,000 min⁻¹ four-step gear driven spindle with an NST No. 40 taper. A 40-position tool storage magazine, 24 m/min rapid feed on all axes and linear scale feedback on X, Y and Z support heavy-duty mold work as well as high-tolerance part machining.
