NEW SUPERTEC UNIVERSAL CYLINDRICAL GRINDER
 10" x 20" MODEL G25P-50H+5C w/Manual Infeed 
 NOTE:  PHOTO SHOWS MODEL w/CII CONTROL
 
 FEATURES:
 - Sturdy rigid-designed workhead offers four selectable speeds from 
 150 to 483 rpm and swivels ±45° for various grinding operations.
 - 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 MT3 center.
 - Cartridge type wheel spindle is equipped with four super precision 
 angular contact class 7 (ABEC) bearings ensure high accuracy.
 - One V and one flat hand-scraped guideways are Turcite coated and 
 incorporated with an automatic lubrication system and micro-stepping 
 motor. Smooth movement of the wheelhead delivers longer way life with 
 superior positioning accuracy and repeatability.  
 - Universal table with variable speeds can swivel +3º/-5º (G20P) and 
 +7º/-9º (G25P) for cylindricity corrections and taper grinding 
 applications.
 - Slideways, leadscrews are continuously lubricated by an auto-lube 
 system to ensure long service life and maintain maximum accuracy.
 - Optional internal grinding attachment swings down into working 
 position easily and quickly. It can grind workpieces with bores 
 ranging from 3/5"-2 ¾" and depth up to 2 ¾".
 - Optional hydraulic tailstock with foot pedal is available for 
 easy loading and unloading of parts.
