A grinding machine is a machine for material removal with geometrically non-defined, bonded cutting edges, where the relative movement between tool and workpiece is rotational or linear. The machine further must provide relative feed and positioning movements between tool and workpiece. The movements between tool support (spindle) …

A demagnetizer, also known as a degausser, uses electromagnets to generate intense, high frequency AC magnetic fields. In response, individual domains realign randomly so their magnetic fields cancel or nearly cancel, eliminating or substantially reducing undesired magnetism. Some degaussers don't use electricity or electromagnets …
