O.D. CHUCKING

Counter Balance Weights: integral with the chuck levers, improve holding ability over conventional chucks on all O.D. applications by reducing centrifugal losses on the jaws.

Long master jaw bearing surfaces and exceptionally strong internal parts also contribute to heavy gripping.

Slugs or Castings: hard serrated inserts with bases are available and these replace traditional hard stepped top jaws and provide:
  • Longer gripping length
  • Better part penetration
  • Improved gripping range
  • Easier change over
  • Better adjacent tool clearance


Bars and Small Parts: master jaw pads are available. Gripping in these pads attached directly to the noses of the master jaws:
 
  • Increased jaw force on part
  • Reduces “bellmouthing” jaw friction and wear
  • Increases accuracy
  • Stabilizes part closer to spindle bearings
  • Provides bar range with fewer changes
  • Provides additional tool clearance
