Machining - Material removal processes
Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
A road map for grinding and finishing stainless steel
A grinder with a low-removal-rate grinding wheel can face significant challenges working with stainless steel. Again, excessive heat can cause bluing and change the material properties. The goal is to keep stainless steel as cool as possible …
