Spinning Process In Sheet Metal Forming

About 90 percent of spun parts can be formed by starting with a blank disk trimmed from standard commercial sheet metal.

Spinning process in sheet metal forming.

Spinning sometimes called spin forming is a metal forming process used to form cylindrical parts by rotating a piece of sheet metal while forces are applied to one side. Metal spinning and flow forming have noteworthy differences in the initial blank or preform used mainly because the final workpiece produced by each process has different requirements. The sheet metal parts that have circular cross section can be made by this process. Metal spinning does not involve removal of material as in conventional wood or metal turning but forming moulding of sheet.

Metal spinning does not involve removal of material as in conventional wood or metal turning but forming of sheet material over an existing shape. The spinning process is fairly simple. Spinning can be performed by hand or by a cnc lathe. The symmetrical parts can be formed over mandrels by using sheet metal spinning process.

A formed block is mounted in the drive section of a lathe. Spinning can be performed by hand or by a cnc lathe. The axis symmetric components formed by using spinning sheet metal forming as shown in figure the spinning metal product such as aircraft engine parts jet engine parts truck wheels and etc. Spinning is a sheet metal forming process in which a metal blank is pressed over a rotating chuck or form mandrel with the help pressing tool to obtain axisymmetric hollow shell.

Metal spinning also known as spin forming or spinning or metal turning most commonly is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. The rotation of sheet metal with high speed on a spinning lathe. Shear spinning is a process related to conventional spinning and is also known as flow turning or spin forging.
