Birson industries offers friction screw press, model fsp. These presses are preferred for hot forming [forgings] and cold coining, embossing, stamping, sizing nonferrous metals. The screw is made of high quality alloy steel and is heat-treated to have great hardness at the same time great elasticity. Flywheel screw presses machines of this type are characterised by the fact that flywheel connected to accelerates at the start of working stroke and then braked to a standstill by the actual forming process. Thus, the entire kinetic energy stored in the flywheel released screw press have not kinetically fixed bottom dead centre point in common with drop forgings itself or by stops in the tool in turn, this results in advantage tool height adjustment is eliminated, forging accuracy is greater. Specifications: nominal capacity - 30 tonnes; dia of screw - 75/3 mm/inch; stroke of ram - 150/6 mm/inch; number of strokes - 30 per minute; size of table - 325 x 350,13 x 14 mm/inch; maximum distance between table and ram - 300/12 mm/inch; minimum distance between table and ram - 175/7 mm/inch; dia of hole in the table - 75/3 mm/inch; and power required - 3/1440 hp.
