Ultrasonic machining (USM)
...work material, the most common being boron carbide. Grit size depends on cutting speed and surface finish but is usually in the range 100 µm (roughing) to 5 µm (finishing). Abrasive concentration is in the range 20–60% (low for large tools), usually in water (although oil is sometimes used for finishing). The slurry is kept at 2–5˚C using a cooler. Common tool...
