Spinning Processing of Copper Alloy Thick Plate Head Parts

The aim of this study was to work out the larger-size head parts of copper alloy material with a thickness of 8 mm. Using the horizontal CNC spinning machine, the head parts were prepared by conventional spinning forming. Through process optimization, conventional spinning was conducted using the horizontal CNC high-power spinning machine, and copper alloy spherical head parts with the thickness of 8 mm were worked out, which widened the processing range of the equipment, created the first example for conventional spinning forming of thick plate, and added a new scheme for the spinning processing of copper alloy spherical parts. In conclusion, it is feasible to work out thick plate head parts of copper alloy material using conventional spinning. This scheme had certain cost advantage as compared with other processing schemes. The key to the success or failure of the spinning process was the solution to material thinning and stick mold for the part.
