High-speed steel. "High-Speed Steel (HSS)" is used for machining nickel-based alloys due to the high degree of toughness for applications with an interrupted cut such as milling, thread cutting, broaching and striking. With nickel-based alloys, cutting speeds between 5 and 10 m/min can be used. The feed rates per tooth can be set relatively ...

Made of nickel alloy, these inserts are more resistant to acids and salt water than stainless steel inserts. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes.

Milling of durum wheat as well as further processing were carried out in a pilot plant. Commercial pasta samples purchased from the local market were also … A study was undertaken to investigate the effect of technological processing in pasta-making on the content of arsenic, cadmium, lead and nickel.

2. Stay Rigid in Your Nickel Alloy Cutting . Making setups as rigid as possible is good advice for any machining application, but especially so for super-tough metals like nickel and nickel-bearing alloys. For milling operations, a shrink-fit holder is often the first choice, with hydraulic or mechanical milling chucks coming in a close second ...
