Workhead swivels 90°CCW to 30°CW for various grinding operations. A dual oil seal and cover prevents coolant seepage into the workhead. - The design of the tailstock is both rigid and robust. Housed in a cast body, the hardened nitralloy steel sleeve is designed to carry a MT4 center for G32/G38 and a MT3 Center forG20/G25. - An Optional hydraulic tailstock with foot pedal is available for easy loading and unloading of parts. - A combination of hydrostatic and hydrodynamic bearings, surrounded by a high pressure oil film, eliminates metal to metal contact to provide high rigidity as well as high vibration damping performance. (Except G20P/G25P) - A pressure switch interlock prevents spindle start-up until oil pressure is established. This pressure switch interlock also stops the spindle if oil pressure fails. - The One V and one flat hand-scraped guideways are Turcite coated and incorporated with an automatic lubrication system, precision ballscrew, AC servo motor and a 0.000004 linear superior positioning accuracy and repeatability. - The Rigid table with box-type structure travels on a cushion of oil with no metal-to-metal contact. - Z-axis positioning accuracy and repeatability is assured with an AC servo motor and high precision, pre-tensioned ballscrews. - A swiveling table dial indicator enables rapid cylindricity corrections and taper grinding applications. - Slideways, ballscrews and spindle are continuously lubricated by an auto-lube system to ensure long service life and maintain - A highly-automated grinding system can be customized with a wide selection of optional equipment…including an automatic OD sizing device, gap control, crash control and touch probe for axial - The hinged, swing-down internal grinding attachment (optional) swings down into working position easily and quickly. A patented locking device adds safety as it prevents the ID attachment from swinging down abruptly.
