"NEW" SUPERTEC MODEL PLANOTEC 1224CII
 3-AXIS FULLY AUTOMATIC HYD. SURFACE GRINDER
 NOTE:  PHOTO IS OF THIS 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 a total of 4  
 preloaded class 7 (p4) super precision angular contact ball 
 bearings to ensure high accuracy and superior grinding finish.
 - Spindle, couplings, and 7.5 HP spindle motor are precisely 
 balanced for low vibration and powerful output to achieve 
 precision grinding accuracy.
 - Double V saddle and table ways are Turcite-B coated and precisely 
 hand scraped to provide smooth movement, better accuracy and  
 longer way life.
 - Both saddle and table travel on Hydrostatic ways, a cushion of oil 
 with no metal-to-metal contact, providing excellent way longevity 
 and accurate positioning.
 - The rigid wheelhead travels on linear slideways and is precisely 
 positioned with an AC servo motor and precision ballscrew to 
 ensure better downfeed repeatability.  The smallest downfeed 
 increment is 0.000010".
 - The crossfeed mechanism incorporates a precision ballscrew, and 
 AC inverter to provide smooth, accurate crossfeed and allows 
 criss-cross grinding for better workpiece finish.
 - The hydraulic & coolant systems are separated from the machine 
 to eliminate vibration and dissipate heat better.  A heat exchanger 
 is used on the hydraulic system to maintain optimum oil temperature.
 - 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 recommended pressure.
 - Mitsubishi PLC control uses a menu-driven LCD touch screen is 
 easy to learn and easy to set up.  Simply fill in the blanks to set 
 total grinding amount, rough increment, fine increment, sparkout 
 passes, feeding direction, parking position, wheelhead retract 
 distance, and press cycle start to complete an automatic grinding 
 cycle.
 - Grinding cycles for CII model:  semi-automatic, surface, plunge, 
 crisscross.
