Below is a list of Deburring Equipment manufacturers from St. Louis, Missouri. Deburring equipment is used to remove unwanted materials from the surface or inner cavities of parts and materials. Referred to as burrs, these unwanted materials include raised edges, small pieces of attached leftover materials and other imperfections that are typically formed during machining processes such as engraving, welding, grinding, drilling and milling. More common than not, burrs can cause problems such as increased stress, decreased fracture resistance, fastener damage and shortened fatigue life.
