Maximum distance from the table surface to the spindle centerline is 24", with an X-Z travel of 32" × 16". The spindle is sup- por ted by six angular contact bearings and is air-cooled to minimize temperature increase and ensure accuracy. Grinding spindle speeds range from 500 to 3,500 rpm with an AC servo power rating of 30 hp. The machine uses a standard grinding wheel measuring 14" in diameter and 3" wide with a 5" bore. The grinder features a single-piece base cast- ing to promote rigidity. The column and wheelhead traverse structure are on precision roller bearings, and the hardened and ground guideways are preloaded and driven by a precision ballscrew for precise positioning. Cross-feed and elevating axes are positioned by precision ballscrews with an AC servomotor for improved accuracy. The elevating encoder device mounted on the top of the elevating ballscrew can directly encode the down-feed amount, eliminating error. The machine's column is driven by precision ballscrew and has a FANUC AC servo-control system. are immediately available from Helfer Tool Company.
