Big Kaiser's FLM, ELM Chipbreakers Designed for Cutting Long-Chipping Metals
Big Kaiser’s FLM and ELM insert chipbreakers are designed to improve surface finish in long-chipping materials.
Big Kaiser’s FLM and ELM insert chipbreakers are designed to improve surface finish in long-chipping materials. Long chips that are difficult to evacuate can lead to poor surface finishes, reduced insert life and machine crashes.
The FLM 3D chipbreaker design, used on PCD-tipped inserts, is well-suited to finishing aluminum components, where traditional flat-top inserts may produce a large nest of chips that is difficult to remove from the bore and/or tool. Three different radius options are available: 0.008", 0.016" and 0.031" for the TCGT2 (1.5) insert.
The ELM chipbreaker, used on cermet inserts, is well-suited to finishing mild or construction steels. Available in a 0.008" radius and combined with a light depth of cut, this chipbreaker provides a high-shear angle to shorten chips, and improve both chip evacuation and finish.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
