SD3000-2 CNC spinning machine is manufactured from European technology, combined with modern CNC technology and advanced processing and testing equipment. This spinning machine is a powerful model developed for spinning processing of high-strength, thick-walled parts. In production applications, the equipment has the characteristics of smoothness, no vibration, large feed capacity, and safe control. The processed product has a smooth surface and a more uniform wall thickness. It can significantly reduce material waste, improve product dimensional accuracy, smooth arc transitions and precise arcs. It can also significantly reduce workers' labor and ensure employees' operational safety. 2. Process principle Place the cut round slab on the center bracket, and use a hydraulic tail jack to press the slab against the end face of the mold. Multi-pass spinning is carried out through the spinning wheel, and the movement trajectory is controlled by the CNC system, which can realize the movement and differential compensation of various contours such as arcs, diagonals, straight lines, etc., to meet the contour requirements of various products. The contour movement of the product is controlled by CNC system programming, which is easy to apply and safe to operate.
