﻿Modern Machine Shop: 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.uuid:4c263912-dc5a-42d1-86ed-ca26dd759f3b;id=77Copyright © Gardner Business Media, Inc. 20142014-07-30T13:09:19Zhttp://www.mmsonline.com/image.ashx?width=125&path=/cdn/cms/thumb_turning-tools.jpghttp://www.mmsonline.com/articles/when-to-consider-customized-cutting-toolsWhen to Consider Customized Cutting ToolsWhat is the real cost of choosing standard or customized tooling if time is money and efficiency translates into profits?

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.2014-06-27T05:00:00-04:002014-07-30T13:09:19Zhttp://www.mmsonline.com/articles/five-process-security-tips-when-parting-offFive Process Security Tips When Parting OffTech Brief2014-05-23T10:25:12-04:002014-07-30T13:09:19Zhttp://www.mmsonline.com/blog/post/video-polygonal-turningVIDEO: Polygonal TurningHere are links to two video samples of a cool process for turned parts that has the potential for considerable time and part cost reductions, versus milling operations, when producing radii.2014-02-05T00:00:00-05:002014-07-30T13:09:19Zhttp://www.mmsonline.com/products/chipbreaker-designed-for-swiss-turningChipbreaker Designed for Swiss TurningSumitomo Electric Carbide offers its MESI Chipbreaker for Swiss turning and small-parts machining, including medical applications. 2014-01-10T15:25:00-05:002014-07-30T13:09:19Zhttp://www.mmsonline.com/articles/innovations-in-five-edged-parting-and-grooving-insertsInnovations in Five-Edged Parting and Grooving InsertsHere's an alternative to the standard circlip-type grooving system, offering five cutting edges with fast indexing from either side. 2013-12-16T14:37:18-05:002014-07-30T13:09:19Zhttp://www.mmsonline.com/articles/new-tooling-improves-machining-cell-outputNew Tooling Improves Machining Cell OutputBy incorporating advanced tooling from Seco Tools, Thern Inc. was able to increase its machine tool capacity and reduce cutting costs.2013-12-01T10:35:00-05:002014-07-30T13:09:19Zhttp://www.mmsonline.com/articles/turbosharge-swiss-type-turning-with-accessoriesTurbocharge Swiss-Type Turning with AccessoriesAdding accessories to the already capable Swiss-type turning center is a cost effective method of increasing production efficiency.2013-11-18T09:40:53-05:002014-07-30T13:09:19Zhttp://www.mmsonline.com/products/bn7000-turning-system-for-cast-iron-machiningBN7000 Turning System for Cast Iron MachiningSumitomo Electric Carbide Inc.’s BN7000 turning system for the machining of cast iron possesses CBN particles that are densely sintered for the maximum CBN content possible, resulting in high wear and breakage resistance. 2013-11-01T00:01:00-04:002014-07-30T13:09:19Zhttp://www.mmsonline.com/blog/post/a-new-formula-for-metal-removal-rates-in-turning-A New Formula for Metal Removal Rates in Turning An expert on cutting tool theory and practice is proposing a new formula for calculating the metal removal rates in turning operations.
