9 Types of Machining Processes to Know About
The first time I stood in a real machine shop, the smell hit me first—a sharp, clean, metallic scent of cutting fluid and hot steel that sticks with you forever. My mentor, a grizzled old machinist named Frank, handed me a solid, six-inch cube of 6061 aluminum. It was heavy, perfectly square, and utterly useless. […]
