The Mycenter-HX630G/800 #40 is a horizontal 4-axis machining center built on box ways with hand-scraped mating surfaces and a 4-step gear driven spindle. It machines large, heavy workpieces on a 630 x 630 mm pallet table with X, Y and Z travels of 1 100, 920 and 1 050 mm. A 50-station tool magazine and 60 m/min rapid traverse support continuous production on fixtured tombstones.
