Rotary Engraving is the process of using a spinning cutter in a motor-powered spindle to cut or “rout” into material, either completely through the substrate to create cut out shapes or holes, or at a predetermined depth to create engraved grooves that form characters and graphics.

Because of the wide range of materials that rotary machines can engrave, including acrylic, traffolyte, glass, ceramic, wood, stone, any type of machinable bare metal, including aluminum, brass, stainless steel (machinable grades), silver, gold, titanium, platinum and solid surface material, rotary engraving is excellent for machine tags, legend plates and permanent marking on fixtures and equipment. For ADA signage, it is easier to create the required raised lettering and Braille dots by rotary engraving.
