Providing chatter-free operation, the ESCO Mongoose MILLHOG(R) utilizes the EscoLock(TM) rigid blade lock system and T-15 tool steel TiN coated cutter blades with a radical chip breaker
that directs the chip away from the tube and minimizes heat generation.
Utilizing an obstruction or groove type chip breaker
is an effective approach to promote chip breaking.
Thanks to its basket arch cutting edges, open chip breaker
groove behind the cutting edge, and reinforced chip breaker
blades it can handle smooth and interrupted cuts.
We can run high feeds with this type of tool in combination with the MF5 chip breaker
geometry, provided that the cutting depth does not exceed 2.
This was caused by changes in the physical properties of the chip (tendency of forming fiber conglomerates or "welding") and the presence of the chip breaker
(a very common accessory in the feeding systems of mini gang sash saws).
In the world of cutting tool inserts, the only real differences between the various brands are the grade and chip breaker
and a C-shaped hooked chip breaker
on the face of the cermet or carbide inserts allows faster chip removal and more aggressive cutting speeds.
The machine features play-free linear guides for a smooth carriage movement, solid-cast iron construction, solid steel crank arms, a precision stop/start feed system, adjustable chip breaker
and an automatic central Lubrication system.
Incorporating a radical chip breaker
to direct the chip away from the tube surface and dissipate heat, the cutter blades can be supplied in styles to match many angles of end prep.
The TNMG 332 insert with PF chip breaker
geometry (figure 1) were made available in STL form, generated from CATIA V5R8 system (Patrascu, 2007).
The combination included an uncoated tungsten carbide insert with a chip breaker
and holder providing a zero-degree lead angle.
A carbide substrate helps resist vibrations that could lead to premature chipping of cutting edges, and a chip breaker
provides control over chip shape and directional flow to increase chip evacuation capacity.
