"NEW" SUPERTEC MODEL STP-2A618
 HIGH PRECISION 2 AXIS AUTOMATIC SURFACE GRINDER
 NOTE:  PHOTO IS OF THE STP-618CII MODEL
 
 FEATURES:
 - 3 HP V3 grade spindle motor for powerful output to achieve 
 precision work standards and better grinding capability.
 - Cartridge spindle w/4 preloaded class 7 (p4) bearings and 
 run-out of taper nose better than 0.000060" T.I.R. provides 
 quiet, vibration free operation for better workpiece accuracy.
 - Optional 0.000050" micro down feed and micro cross feed is 
 available (see below).
 - Vertical handwheel conveniently located at waist level. 
 - The table traverses on linear ball bearings with hardened 
 and ground guide ways to ensure smooth and easy movement of 
 the table.
 - Double V cross ways are hand scraped and Turcite coated for 
 greater flatness and high wear resistance.
 - All castings are tempered and stress relieved twice to assure 
 stability of the machine structure and resist deflection under load.
 - Hardened & ground column ways with cast spindle slide is 
 precision fitted for no "hang-up" gravity down-feed.
 - The Optional Mitsubishi PLC control uses a menu-driven LCD 
 touch screen is easy to learn and easy to set. 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 
 automatic grinding cycle. (on the CII model only)
 - Grinding cycles for CII model:  semi-automatic, surface, plunge, 
 & crisscross.      
 - Work table flatness shall be within 0.00012".
 - The automatic lubrication system continuously floods saddle & 
 column ways, bearings, and lead screws for better machine 
 performance and less maintenance.
