Behind the finished vase are the spinning tools used to shape the metal. 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. [1] Spinning can be performed by hand or by a CNC lathe.
In shear spinning the area of the final piece is approximately equal to that of the flat sheet metal blank. The wall thickness is maintained by controlling the gap between the roller and the mandrel. In shear forming a reduction of the wall thickness occurs. Before the 1950s, spinning was performed on a simple turning lathe. When new ...
Melt spinning is a metal forming technique that is typically used to form thin ribbons of metal or alloys with a particular atomic structure. [ 1 ] Some important commercial applications of melt-spun metals include high-efficiency transformers ( Amorphous metal transformer ), sensory devices, telecommunications equipment, and power electronics.
An English wheel showing four interchangeable lower wheels (anvils), the larger fixed upper wheel, the pressure adjustment screw and a quick release mechanism The English wheel , in Britain also known as a wheeling machine , is a metalworking tool that enables a craftsperson to form compound (double curvature) curves from flat sheets of metal ...
The core element of a rolleron is a metal flywheel that is typically positioned at the trailing end of a fin. The wheel has notches cut into its circumference; these notches intentionally protrude as to maximize their interaction with the airflow.
The wheel type (e.g. cup or plain wheel below) fit freely on their supporting arbors, the necessary clamping force to transfer the rotary motion being applied to the wheels side by identically sized flanges (metal discs). The paper blotter shown in the images is intended to distribute this clamping force evenly across the wheels surface.
Video of concrete pipe production. Centrifugal casting or rotocasting is a casting technique that is typically used to cast thin-walled cylinders. It is typically used to cast materials such as metals, glass, and concrete. A high quality is attainable by control of metallurgy and crystal structure.
This version is the older of the two, as spindle spinning predates spinning on a wheel. A distaff can also be mounted as an attachment to a spinning wheel. On a wheel, it is placed next to the bobbin, where it is in easy reach of the spinner. This version is shorter, but otherwise does not differ from the spindle version.
