Insert Positioning

The Twisted Insert for Cut-Off Setup

and Grooving Applications The optimal cutting edge height above the center of

TANG-GRIP tools is up to 0.08 mm + 0.025 mm Machining depths longer than insert length is made W.O.C., an advantage when cutting solid bar to center possible with the double-ended, twisted insert body.

  • Cut-off as close to chuck as possible
The rear edge is slanted in relation to the frontal• On new applications, first machine in the low or
edge so it does not come into contact withmiddle range of recommended speeds and feeds
the machined groove surface when the tool
penetrates deeply into the workpiece.Machining
  • Consistency of speed and feed improves performance
  • Apply coolant abundantly
  • Secure inserts into clean pockets
  • Cutting forces on soft workpiece materials may be insufficient to push insert well into pocket. Tap insert into place using a plastic hammer
  • On a conventional lathe, lock the carriage to prevent axial motion during cut-off (0.08+0.025) max.

Clamping

Extended, prismatic surfaces guarantee reliable, foolproofCenter Height
clamping even in unstable machining conditions.
Screw-ClampingSelf-ClampingUsage
  • Replace worn inserts promptly, the price of a new one is much less than the risk of damage from continuing with one that is worn out
  • Replace blades that have worn or damaged pockets
  • Never try to repair damaged pockets
  • Chip curling is dependent on the chipformer type and the machining conditions Chipformer Features
  • Narrows the chip
Small diameters (D.O.C.)Large diameters (D.O.C.)• Eliminates friction with groove walls,

  • Permits higher feeds
  • Produces unscratched surfaces, eliminating additional facing
  • Curls the chips into compact spirals for easy disposal
