Cutting Tool Series Increases Tool Life
IMTS 2018: KEO Cutting Tools is displaying the Patriot tool series, which offers versatile tools in a range of options from solid carbide mill to indexable drilling.
KEO Cutting Tools, part of the Arch Global Precision family of companies, is displaying the Patriot tool series, which offers versatile tools in a range of options from solid carbide mills to indexable drills. The tool series is designed to deliver higher-performance results that increase productivity and provide longer-lasting tool life (up to 20 percent for some applications, the company says).
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
The length by which the tool extends from the toolholder is a variable that can be used to 'tune' the machining process. Contrary to what you may expect, increasing the tool's L:D ratio may reduce chatter and result in more productive milling.
A reader recently asked about speed, feed rate and depth of cut when using small tools in steel.
