FEATURES:

. FANUC Oi-TF CNC controller incorporated with two AC servo motors.

. Heavily ribbed box-type base is made of Meehanite castings, providing excellent rigidity to ensure machine stability. 

. Hydraulics, coolant and lubrication systems are separated from machine to eliminate vibration and dissipate heat.

. Generously proportioned, the enlarged and properly sloped drainage troughs underneath the wheelhead base provides rapid coolant drainage needed during heavy duty grinding and prevents thermal distortion of base.

. Sturdy rigid-designed workhead is electronically controlled giving programmable variable spindle speeds.  Workhead is fixed.  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.

. 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.

. 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.

. Linear guideways incorporated with precision ballscrew, AC servo motor and a 0.000020” linear feedback system to ensure smooth movement of the wheelhead for superior positioning accuracy and repeatability.

. Rigid table with box-type structure.  Z-axis positioning accuracy and repeatability is assured with an AC servo motor and high precision, pre-tensioned ballscrews.

. Slideways, ballscrews and spindle are continuously lubricated by an auto-lube system to ensure  

   long service life and maintain maximum accuracy.   

. A highly-automated grinding system can be customized with a wide selection of optional equipments…including an automatic OD sizing device, gap control, crash control and touch probe for axial positioning.
