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.
