When it comes to machining superalloys used commonly in the aerospace, motorsport and medical sectors, solid-carbide cutting tools will only deliver performance to a certain level. To take performance into the stratosphere, cutting tool manufacturer TaeguTec says machine shops should apply ceramic cutting tools, like its CeramicSFeed.

Ceramic tooling requires a change in mindset and machining strategies, but TaeguTec says the dividends are incredible with the correct cutting tool. Unlike solid-carbide tools, CeramicSFeed is capable of machining at cutting speeds up to 1000 m/min at feed rates of up to 0.1 mm/tooth. Suitable for processing nickel-based superalloys such as Inconel at these elevated machining parameters, the CeramicSFeed incorporates TaeguTec’s C3030 grade. A geometry incorporating unequal flute spacing, a high helix angle and an optimised edge geometry with proprietary cutting edge ‘after-treatment’ further drives performance.

Available as a four- or six-flute variant, the new CeramicSFeed TC3030 grade is manufactured from a SiAlON composition that provides durability in shouldering, slotting and ramping operations.

TaeguTec has introduced the TC3030 grade CeramicSFeed with a four- or six-flute CRF variant, or the four-flute high-feed CRH range. The four- or six-flute CRF has been developed with a larger core diameter to increase stiffness and minimise vibration. The high-helix 40° cutting angle and corner radius further extend tool life and improve swarf evacuation during high-feed machining.

In contrast, the high-feed CRH four-flute end mill features a robust, high-strength body that is conducive to machining at high feed rates. This combination makes the four-flute CRH a suitable choice for high-feed facing and ramping applications where maximum material removal rates are a necessity.
