What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Do 3D Printing And CNC Machine Coexist Or Compete?

Many countries in the world have cultivated 3D printing as a new growth point for future industrial development. As early as 2012, the United States identified “Additive Manufacturing Technology” as the first manufacturing innovation center (later renamed “Made in the United States”), and the European Union, South Korea, Japan, Singapore, Russia and other countries also adopted various measures to promote 3D printing China Industry moving forward

Since the rise of 3D printing, China has successively promulgated a number of policies to support the development of the 3D printing industry. With the support of policies, 3D printing companies have sprung up like mushrooms after a rain, and are growing rapidly. The development of the 3D printing industry in Beijing, Guangdong, Zhejiang, Shaanxi and other places has also made significant progress. According to statistics, there are more than 400 companies engaged in 3D printing business in Guangdong Province alone, with multiple 3D printing industrial parks.

With the rapid development of 3D printing, whether traditional subtractive manufacturing methods such as Cnc Machine tools will be replaced has also become a hot topic of discussion among people from all walks of life. In recent years, the technology of China’s CNC machine tools has been improving day by day, and 3D printing has found their own scenes. Generally speaking, CNC machine tools need to program in advance and continuously cut to realize the forming of objects. The working principle of a 3D printer is similar to that of a CNC machine tool, and it also works according to computer instructions. The difference is that it builds products by stacking layers of raw materials. So 3D printing is also called “additive manufacturing.”

The significant difference between 3D printing and traditional manufacturing lies in the process of product molding. In the traditional manufacturing industry, the entire manufacturing process generally needs to be formed through such processes as mold opening, cutting, casting or forging, and component assembly. 3D printing eliminates complicated processes, no molds, and one-time molding. Therefore, 3D printing can overcome some designs that cannot be achieved in traditional manufacturing and produce more complex structures.

On the other hand, CNC machine tools are a type of computer numerical control (CNC), which can process complex, precise, and various parts. Generally speaking, CNC machining tools use computer-designated programs to remove excess materials through laser cutting, milling and other steps to reach the final product, which is a typical subtractive manufacturing.

On the one hand, traditional manufacturing is characterized by “global procurement, division of labor and collaboration”. Different parts of a product are often produced in different places and then shipped to the same place for assembly. And 3D printing is “integral manufacturing, one-time molding”, which eliminates the logistics link and saves cost and time.

On the other hand, the traditional manufacturing industry takes production lines as the core, factories as the main carrier, and highly concentrated production equipment. And 3D printing embodies the integration of a new generation of information technology and manufacturing represented by cloud computing, big data, Internet of Things, and mobile Internet.

As a major product of the development of traditional manufacturing, machine tools are very different from the new generation of 3D printing manufacturing methods. The machine tool is the mother machine of the manufacturing industry. If 3D printing technology can be integrated into the machine tool field, it will undoubtedly be even more powerful. The combination of the two not only improves the production efficiency, but also completes many manufacturing problems.

The special machine tool in the machine tool can be customized with functions according to customer requirements, but the functions are not powerful enough and rich, and may not be designed and manufactured as one wishes. However, with the introduction of 3D printing, the popularity and application of machine tool products may be greatly improved.

It is understood that 3D printing technology has already been applied in China’s industrial parts manufacturing, but has not yet entered large-scale industrial applications. Its process and equipment, as well as applications in medical, aerospace and other fields need to be further developed. Judging from the current situation, 3D printing technology does not have the conditions to replace traditional manufacturing. In terms of mass manufacturing, the high-efficiency and low-cost traditional subtractive manufacturing method embodied by machine tool manufacturing is even better.

Of course, with the emphasis on metal additive manufacturing, more and more equipment manufacturers in the field of traditional machine tool manufacturing have entered the field of additive manufacturing. Some have launched hybrid additive manufacturing equipment based on Cnc Machining centers, and some simply Directly enter the new field of additive manufacturing. For example, Japanese Mazak. Mazak launched the Integrex i-400am (additive manufacturing) compound processing equipment. Integrex i-400am is a complete set of equipment, which is more suitable for processing materials for small batch production, such as the processing of heat-resistant alloys for aerospace parts, and the processing of high-hardness materials for parts.

The long-term coexistence of subtractive manufacturing and growth manufacturing methods is a trend that can be met. However, in the future, this situation may change. In any case, the way to achieve refined, automated, and efficient manufacturing of products will be expected to be diversified.
