Dishing Sheet Metal

Flat heads and dished heads 9 230 mm.

Dishing sheet metal.

Reverse dished heads can be accommodated with additional tooling. Dishing the metal into a hollow or depression in the end of a log works but unless you have a lathe to quickly turn out a bowl shaped depression you must carve a hollow by wood chisel or simply repeated pounding. Both of these latter methods take time and all three presuppose a handy wood source. While sinking is a relatively fast method it results in stretching and therefore thinning the metal risking failure of the metal if it is sunk too far.

Sinking also known as doming dishing or dapping is a metalworking technique whereby flat sheet metal is formed into a non flat object by hammering it into a concave indentation. Drilling is done in sheet metal only when piercing cannot deliver the accuracy required. The maximum major axis diameter is 9 2750 mm with a maximum major minor axis ratio of 2 1. For example on a formed part when holes on different features need to be coaxial the accuracy obtained by machining may be required.

The method of cold dishing metal plate having the characteristics of boiler plate which consists in successively depressing 1 different portions of the plate an equal amount and in such manner as. Maximum depth of dish can be sheared flanged on the model 87 using the equipment that is standard on the machine. Not really they ll send the clown after me.
