Extreme Cold is a Hot Technology
Despite its name, coolant often doesn’t provide much cooling. Here’s a different approach to enhancing tool life that involves dramatically cooling the tool.
Coolant lubricates a machining process and clears chips. Despite the name, however, it often doesn’t provide much cooling. A very different approach to enhancing tool life involves dramatically cooling the tool—using fluid colder than -300ºF. As this article describes, cryogenic machining might deliver the next dramatic leap forward in tool performance.
