Ball burnishing is also used as a deburring operation. The surface of ancient terra sigillata vessels did not require this burnishing or polishing. After being cut the gear can be finished by shaving, burnishing, grinding, honing or lapping. Secondary tooling methods include trepanning, skiving and burnishing, pull boring, or bottle boring. Roller burnishing, or surface rolling, is used on cylindrical, conical, or disk shaped workpieces. Burnishing also occurs to some extent in machining processes. In both cases, a burnishing tool runs against the workpiece and plastically deforms its surface. The feedrate for burnishing is that associated with 'rapid traverse' rather than finish machining. The plastic deformation associated with burnishing creates greater heat and friction than from rubbing alone. Typical applications for roller burnishing include hydraulic system components, shaft fillets, and sealing surfaces. The plastic deformation associated with burnishing will harden the surface and generate compressive residual stresses. Pottery was both fine and coarse featuring red washing, burnishing and incisions. On burnishing drills there are 4 or more lands, similar to reamers. Creating the polished finish with the stone is called burnishing. "Barrel burnishing" is a type of barreling where no cutting action is desired.
