CNC Metal Spinning Technology

Shaoxing Huida Metal Factory | Updated: Jun 16, 2017

CNC Metal Spinning technology

The thin-walled rotating body shell made by CNC Metal Spinning technology solves the technical problems such as low rigidity, high vibration and low precision, which can be processed at the time of turning, and has many advantages in the aerospace field.


The United States powerful spinning production φ3900mm large missile shell, radial size accuracy of 0.05mm, surface roughness Ra 1.6 ~ 3.2μm, wall thickness ≤ 0.03mm. US titanium manufacturing company with 1.5m vertical spinning machine spinning φ1524mm Ti-6Al-4V titanium alloy missile pressure vessel head, each head of the spinning time of 5min. Militia Intercontinental Missile The second stage solid engine shell uses Ti-6Al-4V titanium alloy, and with a strong CNC Metal Spinning, after forming the titanium alloy shell weight reduction of 30%. A large-scale Ti-15V-3Cr alloy propulsion system tank for φ1905mm was prepared by CNC aerodynamics, and was applied to the European Alfa communication satellite giant platform. Significant weight loss of the satellite platform, increasing the payload.


China's CNC Metal Spinning and equipment research from the early 1960s, titanium alloy spinning began in the last century 70's, after 40 years of development, the basic form from the equipment development to the development of a mature system The Titanium alloy and spinning products used in domestic aerospace, such as rocket engine shell, blade cover, gyroscope guide hood, Inner skin, etc., Ti8Al1Mo1V high titanium alloy for engine blade heat treatment to strengthen titanium alloy CNC Metal Spinning; TB2 titanium alloy for small spray Tube spinning and so on.


Xi'an Aerospace Power Machinery Factory developed the largest diameter of the titanium alloy cylindrical parts; through the positive and negative pass with two straight turn spirals φ500mm thin-walled semi-circular titanium ring, parts for spacecraft micro-dynamic attitude adjustment.


China University of Aeronautics and Astronautics Corporation 703 Institute of the use of universal rotation and strong spin-coupled technology to TC3, TC42 kinds of titanium alloy sheet for the blank, hot spinning prepared two kinds of titanium alloy hemispherical (φ 522mm × 2.0mm ), A cylindrical tank body (φ163mm × 2.0mm × 200mm cup, φ163mm × 2.0mm × 360mm and φ112mm × 6.0mm × 1000mm cylindrical).


In recent years, with the development of computer simulation technology, numerical simulation has been widely used in the analysis of metal parts CNC Metal Spinning process. Institute of Aerospace Materials and Technology, the computer simulation of TC4 cylindrical parts was carried out. The influence of the parameters such as the angle of rotation of the rotary wheel, the trajectory of the wheel and the frequency of the rotation was analyzed. Of the TC4 titanium alloy cylindrical parts. Although the numerical control spinning technology for the field of space to provide a variety of alloy spinning rotary high diameter ratio spinning parts, but from the parts of the engineering applications and numerical control spinning complexity analysis, need to be further strengthened. In general, the spinning technology in the domestic aerospace industry has been widely used, but the large diameter, thin-walled titanium alloy hot CNC numerical control spinning has no application examples, diameter 2.25m tank bottom whole spinning technology, diameter 5m low temperature storage Box bottom melon molding, titanium alloy and high temperature alloy complex structure forming technology is still in the process of exploring the stage.


CNC Metal Spinning technology


Since the 20th century, 90 years, with the rapid development of computer technology, laser direct manufacturing technology has become a hot topic in the field of manufacturing research. There are two methods in laser direct rapid prototyping that can be used to directly fabricate metal parts, namely, Selective Laser Melting (SLM) and Near King Forming (LENS). The research on laser direct rapid prototyping technology of large-scale titanium alloy structure mainly focuses on the United States. US AeroMet company in 2002 to 2005 to achieve a direct laser forming titanium alloy structure in the application of aircraft.
