ISILIK dampened boring bars make it possible to maintain good
productivity and close tolerances for long tool overhangs.
Minimize the tool overhang and select the largest possible
bar diameter in order to obtain optimum stability and
Clearance between the boring bar and the inside of the bore
is extremely important for chip evacuation and to avoid radial
Due to the design of the turret in a CNC lathe, the rigidity
is usually reduced, so for the best result, ensure a clamping
length of minimum 4 x Dm.
For the best performance of the boring bar, the contact,
design and dimensional tolerance between tool and tool
holder are important factors. The best stability is obtained
with a holder that completely encases the bar.
Cylindrical holder with screws are not recommended.
