The chairman of the National Committee of the Chinese People's Political Consultative Conference and the chairman of China Iron and Steel Research and Technology Group Co., Ltd. gave a "Proposal on Strengthening the Close Combination of New Materials R&D and Advanced Manufacturing" to reveal the development of China's new materials industry.
In recent years, the development of China's materials field has made great progress, and high-tech research in the field of materials has reached a considerable level, and a number of new material products with independent intellectual property rights have been obtained. However, in general, China's materials and manufacturing sectors are still large but not strong, core technologies and key components are subject to people; product quality problems are prominent, lack of high value-added products and equipment, has become a development constraint; industrial structure is irrational, intensive The degree is low, most of them are still in the middle and low end of the value chain; resource utilization efficiency is low, energy consumption is high, and environmental pollution is serious.
In the latest technological development plans of the United States, the European Union, Japan, and South Korea, new materials technologies are listed as key technologies to support them. Materials science and technology are also facing new breakthroughs, such as high-temperature superconducting materials, nano-materials, etc. are undergoing rapid development. It can be said that the breakthrough of new material technology will bring huge economic and social benefits. For building materials and manufacturing powers, we must give full play to the decisive role of the market in resource allocation, build a new system of open economy, and stimulate the vitality and innovation of materials and manufacturing industries. Based on this, the members were advised:
First, in the various programs supported by the government, we will implement the idea of â€‹â€‹â€œfirst-generation materials, first-generation equipmentâ€, focus on major needs and major projects, and break through the development, engineering and application of key new materials in accordance with the material support and integrated application characteristics. Key technologies to build a number of national public infrastructure platforms.
The second is to place the manufacturing industry in a more important position, with digitalization, networking and intelligence as the core, vigorously develop strategic emerging industries and advanced manufacturing industries, widely implement digital manufacturing and intelligent manufacturing, accelerate the transformation and upgrading of traditional industries, and improve high-end. The proportion of manufacturing industry, to create an upgraded version of China's manufacturing.
CNC Machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers.
CNC mills are capable of running on programs comprised of number- and letter-based prompts, which guide pieces across various distances. The programming employed for a mill machine could be based on either G-code or some unique language developed by a manufacturing team. Basic mills consist of a three-axis system (X, Y and Z), though most newer mills can accommodate three additional axes.
In lathe machines, pieces are cut in a circular direction with indexable tools. With CNC technology, the cuts employed by lathes are carried out with precision and high velocity. CNC lathes are used to produce complex designs that wouldn`t be possible on manually run versions of the machine. Overall, the control functions of CNC-run mills and lathes are similar. As with the former, lathes can be directed by G-code or unique proprietary code. However, most CNC lathes consist of two axes - X and Z.
CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. A turret, with tooling attached is programmed to move to the bar of raw material and remove material to create the programmed result. This is also called [subtraction machining" since it involves material removal. If the center has both tuning and milling capabilities, the rotation can be stopped to allow for milling out of other shapes.
The starting material, though usual round, can be other shapes such as squares or hexagons.
Depending on the bar feeder, the bar length can vary. This affects how much handling is required for volume jobs.
CNC lathes or turning centers have tooling mounted on a turret which is computer-controlled. The more tools that that the turret can hold, the more options are available for complexities on the part.
CNC`s with [live" tooling options, can stop the bar rotation and add additional features such as drilled holes, slots and milled surfaces.
Some CNC turning centers have one spindle, allowing work to be done all from one side, while other turning centers, have two spindles, a main and sub-spindle. A part can be partially machined on the main spindle, moved to the sub-spindle and have additional work done to the other side this configuration.
There are many different kinds of CNC turning centers with various types of tooling options, spindle options, outer diameter limitations as well as power and speed capabilities that affect the types of parts that can be economically made on it.
CNC grinding is a machining technology which utilizes a high-tech ultramodern type of grinding machine known as a CNC grinding machine. The CNC technology, also known as Computerised Numerical Control, is an automation process that utilizes computer programs to control grinding machines.
