Turning Tools

Turning involves a fixed and non-rotating cutter, because in turning, the workpiece spins instead of the tool. Turning tools typically consist of a replaceable insert in a turning tool body. The insert can be distinctive in a number of ways, including shape, material, coating and geometry. The shape can be round to maximize edge strength, diamond-shaped to allow a sharp point to cut fine features, square, or even octagonal to increase the number of separate edges that can be applied as one edge after another wears out. The material is typically carbide, though ceramic, cermet or diamond inserts can be applied to more demanding applications. A variety of protective coatings also help these insert materials cut faster and last longer. The geometry of the insert generally relates to its cutting angles, though the tool may also include a complex chipbreaker pattern that prevents long unbroken chips from becoming entangled in the cut. The turning tool body generally does not feature quite so much engineering, but even here there are a range of choices for fine-tuning the process. Quick-change tools involve modular bodies that allow replacement tool bodies to be swapped in and out and locked in place quickly to minimize setup time. The turning tool body can also channel high-pressure coolant more effectively to the cutting edge of the tool.

See The Tool's Value Instead Of Its Cost


This company is embracing high-performance tooling on its turning centers. The "sticker shock" is no reason not to do this. In one case, though, the shop found a way to limit the cost of the tool and increase productivity at the same time.



When to Consider Customized Cutting Tools

By: Chris Koepfer (editor)
What is the real cost of choosing standard or customized tooling if time is money and efficiency translates into profits? It’s a question many shops face regularly.

In the Groove for 50 Years

By: Mark Albert
It’s an American success story. In 1964, William and Hazel Kaiser founded a company to produce and market Thinbit, an innovative line of grooving tools. At first, the business operated out of the couple’s attic and garage. Fifty years later, the Kaiser Tool Company’s products continue to help shops such as Mack Tool and Engineering with successful solutions for demanding grooving applications.
