Spinning - cost savings
Critical defense and aerospace applications, titanium has been crucial. The high cost of titanium, a longer delivery time is the main factor affecting the application. Currently, in some difficult to produce thin-walled, cylindrical parts production, more and more widely used spinning process, which can significantly increase economic efficiency. Net spinning process is often used as a molding process, it requires less material to manufacture parts to reduce the secondary processing operations related costs. Advanced materials such as titanium, etc. usually performed only by forging rod or billet production, can now be successfully spinning a tubular member made of precision. Seamless aspect ratio of up to 50:1 parts by spinning manufacturing process can achieve maximum cost savings.
Spinning process
Spinning is a net shape process, this process that the components can be approximated diameter, wall thickness, flatness, roundness and concentricity requirements of dimensional accuracy. A cylindrical workpiece, means "preform"
, Fixed to a rotary shaft, CNC control three rolls on the outer diameter of the preform is applied hydraulic pressure. When the preform is compressed to a stress greater than the yield strength and plastic deformation or "occurrence of plastic deformation", it can achieve the desired geometry. Since the wall thickness of the preform by the wall by three rolls, and thus, the rotary shaft material is elongated and formed. This cold working process can be improved mechanical properties, while refined microstructure, grain orientation texture. Dimension accuracy is usually much higher than the hot forming process the achievable accuracy.
Economic
With the high prices titanium, saving material is essential. Preform is typically four times shorter than the final spinning parts. Short preform easily from solid blanks, thick forging, extrusion and / or hot isostatic pressing to obtain the powder material machining. Short preform machining and machining parts must be compared with full-length can save a lot of material. In addition, net shape or near net shape of the spinning parts can usually be necessary to reduce or eliminate costly machining times and secondary processing operations. Must avoid the thin-walled material for finishing, eliminating vibration or "chatter" problem, which is a very good point. When the material is hard, difficult machining, this process is particularly attractive.
