Variable-Helix End Mills Interrupt Chatter
IMTS 2018: Mastercut Tool Corp.’s V4 Ultra line of end mills combines variable-helix, four-flute geometry with a honed cutting edge.
The PowerN coating carries a blue to red color. At approximately 4,500 Vickers, the coating is tough. Performing best in rigid setups, it is said to be useful in applications involving superalloys, hard materials, and high-heat applications. According to the company, he coating reduces friction, enables increased speeds and feeds, and improves tool life. The end mill geometry is designed to interrupt chatter for gains in longevity, throughput and surface finish in materials ranging from cast iron to steel to titanium.
Consider these alternatives when conventional drilling can't do the job.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
Simple process considerations can increase your productivity in milling titanium alloys.
