SUPERTEC MODEL STP-618M
HIGH PRECISION HAND FEED SURFACE GRINDER
 
 
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.      
- Indexable table handwheel for ease of operation.
- 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.
