Hardware · `Mycenter-HX500iG/630 #40` · verification: source checked

The Mycenter-HX500iG/630 #40 is a horizontal 4-axis machining center with a 500 x 500 mm table and a 20,000 rpm 4-step gear-driven, dual-contact spindle with NST No. 40 taper. Axis travels are 870 mm in X, 800 mm in Y and 930 mm in Z, with 60 m/min rapid feed on the linear axes. A 50-position tool magazine and a two-pallet changer with a direct-drive 4th-axis rotary table support continuous production of medium to large parts.
