Tungaloy Boring Bar System Features Vibration Dampening

Tungaloy has expanded its BoreMeister vibration-dampening boring bar system by adding 14 new modular cutting heads for internal profiling and threading applications.

The BoreMeister system features a variety of exchangeable heads and shanks for internal turning, profiling, threading and grooving. The system provides vibration-free boring operations in a long overhang setup of up to 14 × D through a dampener inside the tool body. In addition, the boring bars are also available in solid steel shanks or with a polygon-shank coupling machine-side connection. 

The new modular profile cutting heads hold a DC..07 or DC..11 insert and has a 62.5-degree approach. According to the company, they provide improved stability, greater flexibility and significant productivity gains for internal applications such as bore diameter expansion, contouring of complex 3D surfaces with varying diameters and chamfering of internal hole entrances that are located deep inside the hole. The new thread-cutting heads are designed for large threading inserts in size 22 and 27 that form ISO metric threads and trapezoidal threads.
