Supertec

Feature

Sturdy rigid-designed workhead is electronically controlled giving variable spindle speeds ranging from 30-350RPM.

Cartridge type wheel spindle is equipped with four super precision class 7 (ABEC) bearings.

One V and one flat hand-scraped guideways on the weelhead are Turcite coated and incorporated with an automatic lubrication system, precision ballscrew, and A.C. servomotor (NC version only) to ensure smooth movement of the wheelhead which delivers longer way life with superior positioning accuracy and repeatability.

Slideways, ballscrew is continuously lubericated by an auto-lube system to ensure long service life and maintain maximum accuracy.

Conversational PLC control uses a menu-driven LCD touch screen that is easy to set. Simply fill in the blanks to set total grinding amount, rough increment, fine increment, spark-out passes, feeding direction, parking position and retracting clearance. Press cycle start complete the automatic grind cycle. (NC models only)

Automatic trim compensation.
