Video: Maximizing Cutter Life
A shop owner describes his simple approach to evaluating cutting tool performance and finding the best parameters.
Doug Noxell, owner of Surkut Machine Technology in London, Ontario, describes how he evaluates cutting tool performance to ensure that he is running at the best parameters. “In the first 10 or 15 minutes, you can get a lot of information,” he says. Once wear has begun, the level of wear or chipping indicate specifically how to adjust speed and feed rate. In this video from MMSOnline contributor Todd Schuett, Mr. Noxell explains his tool-observation technique.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
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.
