CNC (Computer Numerical Control) spinning, also known as metal spinning, is a metalworking process where a sheet or tube of metal is rotated at high speed and formed into a symmetrical part by pressing against a spinning mandrel. This process, traditionally performed manually by skilled artisans, has evolved significantly with the advent of CNC technology, enabling automated, precise, and repeatable production. CNC spinning software plays a critical role in this evolution by providing the necessary tools for designing, simulating, and controlling the spinning process. These software solutions enable manufacturers to create complex shapes with high accuracy, reduce material waste, and increase production speed, making CNC spinning an integral part of various industries, including aerospace, automotive, and consumer products.The success of Read more

Metal spinning, also known as spin forming or metal turning, is a metalworking process that dates back several centuries. It involves rotating a metal disc or tube on a lathe and shaping it using various tools to form axially symmetric parts. This traditional technique has been transformed significantly with the advent of Computer Numerical Control (CNC) technology, leading to the modern process known as metal CNC spinning. Metal CNC spinning combines the precision of CNC machining with the traditional art of metal spinning. This advancement has revolutionized the manufacturing of symmetrical metal parts, allowing for greater accuracy, repeatability, and efficiency. The invention and evolution of metal CNC spinning is a fascinating story that intertwines with the broader development of metalworking Read more

Spinning is a process method that uses a tool to continuously apply pressure to a very small part of the workpiece to gradually shape it. Spinning deformation is a local progressive deformation, and its progressiveness is similar to swing rolling. According to the deformation characteristics of spinning, the spinning process can be divided into two categories: ordinary spinning and high-power spinning [1]. Using software to simulate the high-power spinning process can clearly obtain the required data and effectively prevent defects in actual production. Software modeling and simulation  In this paper, the metal forming software Simufact is used to simulate the high-power spinning process. The simulation process ignores the influence of gravity and metal inclusions, and ignores the influence of temperature Read more

In order to machine 3 mm thick large-size cylindrical Al alloy part with curvilinear generatrix followed by straight- walled section, power-conventional spinning combination method supplemented with heat spinning via horizontal CNC spinning machine was explored through process tests, namely, power spinning of the conical curve section at the small end fol-lowed by multi-pass heat conventional spinning. It has been proved that power-conventional spinning combination method is feasible for the machining of large-size Al alloy cylindrical parts with cone-curved profile. Part blank design, necking amount of conventional spinning and part expanding are primary factors affecting the success of the above spinning processes. A certain aluminum alloy cylindrical part is a large-sized cylindrical part with a small taper curved generatrix connected to Read more

A metal lathe is a fundamental machine tool used in metalworking for shaping metal and other materials through rotational cutting. It has been essential in manufacturing and engineering for over a century, evolving from manual lathes to sophisticated computer-controlled systems. The speed at which a metal lathe spins, or its rotational speed, is a critical parameter that influences machining efficiency, surface finish, tool wear, and overall productivity. This article provides a comprehensive overview of the factors affecting lathe speed, the types of lathes, and the implications of different speeds in metalworking. Historical Context Of Metal Lathe Rotation Speeds The metal lathe’s origins can be traced back to ancient Egypt and Greece, where primitive forms of the lathe were used for Read more

Spinning, a fundamental process in the textile and metalworking industries, involves the manipulation of materials to create fibers or shapes through rotation. There are several variations of spinning, with power spinning and normal spinning being two primary techniques. This article elucidates the differences between power spinning and normal spinning, highlighting their unique applications, advantages, and processes. Normal Spinning Normal spinning, also known as conventional spinning or hand spinning in the context of textiles, is a traditional method employed for centuries. In metalworking, normal spinning refers to a technique where a metal disc is rotated at high speed and formed into an axially symmetric part. Process Textile Spinning: Material Preparation: Raw fibers, such as cotton or wool, are cleaned and carded Read more
