Every company has efficient and cost-reducing deburring solutions, but most also have a number of poor practices. This chapter details the poor common practices happening today. Then, it discusses good management and hands-on operator practices. Generally, the fastest manual-deburring processes for job-shop operations include sanding-like operations, brushing and countersinking, and tube or bar end chamfering. Hand-fed mechanized machines provide low cost and relatively rapid deburring and finishing with little investment and floor space. Hand scrapers are fast, but precision knife work is relatively slow. Swivel-blade tools are among the fastest and lowest- cost methods of deburring straight edges and long contours. Because of the geometry of intersecting holes, many hand-deburring tools are not useful. Normally, the following tools are used: drills, reamers, bur balls, cross-hole deburring brushes mounted dental points, abrasive-filled rubber dental points, abrasive cord and tape, abrasive-filled nylon fibers, abrasive silicon-carbide balls on brush fibers, miniature hand stones, pin vises, and dental motors. Some materials have safety or health considerations that require different or more controlled approaches to hand deburring.
