Advantages

  • Uses standard or micro adjusting 1.500" Cri-Bore boring heads
  • Modular system that allows you to use CAT, BT, or HSK shanks
  • Increased RPMs due to low center of gravity to the machine spindle
  • Can rotate boring heads 180 degrees for external turning

 

Features

  • Standard Cri-Bore provides adjustment of .001” or .02mm on diameter
  • Also offered in micro adjustment for .00005” or .001mm on diameter bore increments
  • Extender bars provide 1.125" diameter range of adjustment
  • Seven extender bars provide a diameter range from 5.000" - 12.125" (127.00mm - 307.90mm) for internal bores
  • External turning diameter range of .710" - 7.830" (18.10mm - 198.80mm)
