The pressure moulds we usually use are relatively simple and locally deformed, and the function is to use equipment with low power and tonnage and to process parts, which are generally used in parts with small batch and complex shapes. The working principle of CNC spinning machine is to make use of high-speed rotation of workpiece. A strong external force squeezes the workpiece on a certain path, and the roller repeatedly pushes on the material, making it from point to line and from line to surface, finally causing deformation of workpiece and forming the shape we need. The selection of CNC spinning machine is determined by spinning process and various molding process conditions.

Numerical control spinning machine can finish various work such as drawing, rib pressing, closing, sealing, flanging and crimping. Due to the spinning process, the workpiece has different shapes, so it has a wide range of USES. The numerical control spinning process includes spinning, expanding, edge rolling and so on. What needs to be understood is that deep drawing, expansion rib, contraction end and crimping, in these forms, general spinning can satisfy both integral and local forming. In the modern spinning machine, according to the different technical requirements of the workpiece of different specifications, the methods such as cold spinning and hot spinning can be adopted to carry out corresponding plastic forming.

There are many kinds of CNC spinning machines in use in the market now. From the processing varieties: processing shell type CNC milling machine, processing shaft CNC lathes and so on; The control requirements of machining include: single axis CNC sand belt polishing machine, five linkage CNC gear cutting machine, but in order to meet the market demand, the existing CNC spinning machine is not enough.

Today's key development direction of CNC spinning machine: 1. High speed CNC spinning machine, high speed to achieve high efficiency. To reach this new level, the drive, mechanical drive, mechanical structure and cutter of the CNC spinning machine should be greatly improved. Intelligent CNC spinning machine, modern society, electronic technology, microcomputer, sensor and control system integration, the transformation of traditional engineering machinery products, computer-aided design, aided manufacturing and aided management equipment engineering machinery manufacturing industry, so that people see a new engineering machinery industry.

From the 1980s to the beginning of this century, domestic and foreign spinning equipment technology has gone from a mature period to a modern period. With a new technological revolution, the comprehensive technical level of engineering machinery products has jumped to a new level. Electronic technology, microcomputer, sensor, electro-hydraulic servo and control system integrated renovation of the traditional engineering machinery products, computer aided design, equipped with auxiliary spinning equipment and auxiliary management of engineering machinery manufacturing industry, IT network technology is also equipped with engineering machinery sales and information transmission system, allowing people to see a whole new construction machinery industry. New engineering machinery products of spinning equipment are incomparable in aspects of work efficiency, operation quality, environmental protection, operation performance and automation degree, and are marching towards further intellectualization and robotization.
