  • Mill (grinding)Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water (). Relief is usually not noted until polishing begins so it is important to begin the preparation with grinding media that will keep the samples as flat as possible. However for the best possible starting conditions MD-Largo should be used for fine grinding of materials with a hardness below 150 HV and MD-Allegro should be used for fine

  • Low-Force Low-Heat Grinding Of Tough Materials Additive

    The resulting electrochemical oxidation produces a soft hydroxide film on the workpiece surface that is "scrubbed away" by the abrasive wheel at a much lower force than a traditional grinding operation. Because there is minimum grinding pressure between wheel and workpiece the process generates very little heat.
