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 such as aluminium or steel.
The process of using an English wheel is known as wheeling.It has the key advantage that it can flexibly produce different panels using the same machine. It is a forming machine that works by surface stretching and is related in action to panel beating processes.
It is used wherever low volumes of compound curved panels are required; typically in coachbuilding, car restoration, space frame chassis racing cars that meet regulations that require sheet metal panels resembling mass production vehicles,car prototypes and aircraft skin components. English wheel production is at its highest in low-volume sports car production, particularly when more easily formed aluminium alloy is used.
