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. 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.
Consider these alternatives when conventional drilling can't do the job.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
