"NEW" SUPERTEC MODEL STP-1022A 
 2-AXIS AUTOMATIC HYDRAULIC SURFACE GRINDER 
 w/Power Elevation
 NOTE:  PHOTO IS OF AN ADCII 3 AXIS AUTOMATIC MODEL
 
 FEATURES:
 - All essential castings are rib reinforced to provide a rigid machine 
 structure for long lasting accuracy and stability. 
 - The precision cartridge spindle is equipped with 4 preloaded 
 class 7 (p4) super precision angular contact ball bearings to ensure 
 high accuracy and superior grinding finish.
 - All guideways are Turcite-B coated and precisely hand scraped to 
 provide smooth movement for better accuracy and longer way life.
 - The rigid wheelhead travels on wide-contact hardened and ground 
 guideways.
 - Crossfeed mechanism incorporate with a precision leadscrew, 
 AC inverter provides smooth, accurate crossfeed and allows criss-cross 
 grinding for better workpiece finish.
 - Hydraulics, coolant systems are separated from machine to eliminate 
 vibration and dissipate heat. 
 - All moving surfaces and rotating parts are continuously lubricated 
 by an auto-lube system to ensure long service life and maintain 
 maximum accuracy. An alarm light will illuminate if oil pressure drops 
 below required pressure.
