Planishing. Diagram of planishing, showing planishing hammer, workpiece, and planishing stake (hammer not to scale) Planishing (from the Latin planus, "flat") [1] is a metalworking technique that involves finishing the surface of sheet metal by finely shaping and smoothing it.

Planishing is a highly effective technique used to reduce weld build-up and enhance the surface finish of welded areas. Planishing is Effective on a Range of Materials. Planishing is a very popular process because of the variability of materials that it can handle.
The process involves striking the metal surface with a highly polished Planishing or Collet Hammer whilst it is held firmly against the surface of a highly polished Planishing Stake. This imparts a polish on to the beaten metal surface and also Work Hardens the previously Annealed sheet.
Planishing is a skilled technique, whereby a planishing hammer is used to hammer a patterned finish into the surface of a metal (normally sheet metal). Copper is often given a planished / hammered finish. The copper is first softened through a heat treatment process called ‘annealing’.
Planishing is a technique used to curve and shape thin pieces of sheet metal. The process involves tapping the metal with a specialized planishing hammer while it rests on a rounded stake in order to smooth defects and achieve the proper curve.
Planishing is a technique for smoothing out small irregularities. The formed sheetmetal is held between a smooth, flat, and relatively hard hammerhead and a hard dolly that matches the contour of the part.
Apr 1, 2004 · A planishing hammer is a good tool, but it might be one of the most commonly misunderstood metalworking tools on the market today. It was never intended to be a primary metal shaping tool. It is...
Jun 25, 2019 · Planishing passes, designed to remove waviness produced during the various stages in the spinning process, involve high feed rates to minimize tangential flow. A final roller pass enhances the surface finish by reducing the feed and speed while applying a relatively high radial force.
Raising and planishing are the processes used to make hollow forms such as cups and bowls from flat sheets of metal. Raising is done cold, in stages called courses, which gradually bring up the sides by hammering the metal on anvils and metal forms called stakes.
