FEATURES:

- FANUC OI-TC CNC CONTROL, FANUC AC DRIVES AND SERVO MOTORS,

WITH 2 YEAR FANUC WARRANTY.

- HEAVILY RIBBED BOX-TYPE BASE IS MADE OF MEEHANITE

CASTINGS, PROVIDING EXCELLENT RIGIDITY TO ENSURE MACHINE

STABILITY.

- TABLE IS FULLY SUPPORTED IN THE FULL TRAVEL TO AVOID OVERHANG.

- 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 VARIABLE SPINDLE SPEEDS. 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 FEEDBACK SYSTEM TO ENSURE SMOOTH MOVEMENT OF THE WHEELHEAD FOR 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 MAXIMUM ACCURACY.

- 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 POSITIONING.

- 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. (EXCEPT G32A/38A SERIES)
