TOOLING AND WORKHOLDING MMS NOVEMBER 2018 116 Turning Grades Meet Demand for HRSA Machining in Aerospace Sandvik Coromant introduces two new ceramic insert grades that are capable of performing high-speed, high-security turning operations on components made from demanding HRSA (heat-resistant superalloy) materials. The CC6220 and CC6230 ceramic grades are developed to machine demanding materials where whisker ceramics and SiAlONs fall short. Their ability to handle higher cutting speeds contributes to reduced cost per component, while inherent machining security ensures that quality is not compromised, according to the company. The company claims that there is growing demand for aerospace engine parts that can withstand extreme tem- peratures beyond the capability of those made from Inconel and other high-performance superalloys. Although these powder metallurgic materials can be tailored to handle substantially higher temperatures, they are more difficult to machine than common HRSAs. CC6220 and CC6230 are said to excel when turning demanding materials in intermediate-stage machining. One of the most common applications to benefit is expected to be turbine disc turning, the company says. Aside from the aerospace industry, other sectors expected to benefit from CC6220 and CC6230 include power generation (turbine components in Inconel and Hastel- loy, for example), and oil and gas (parts cladded with Stellite 6, for example). | Sandvik Coromant Inc. 201-794-5000 Indexable-Insert Drill's Polished Surfaces Resist Wear Walter USA has introduced the D4140 indexable-insert drill, a tough and versatile new drill designed to deliver maximum process reliabil- ity and extend tool life. The tool's advantages are said to stem from its design and construction, featuring a hardened and polished surface that offers high resistance to friction wear.
