With the rapid development of modern machining and machining technology, many advanced machining technology methods emerge slowly, such as micro machining technology, rapid prototyping technology, precision ultra precision machining technology, etc. The development of modern tool manufacturing industry is faced with the severe challenge of mastering and developing high-performance new tool materials, new exterior coating technology and special digital manufacturing technology for cutting tools. The high cost of introducing foreign advanced equipment is only one aspect of the problem. In fact, many new materials, new coatings and manufacturing soft technologies are facing the technical blockade of multinational groups and must be developed and mastered by themselves.
Rapid prototyping technology is developed in the 20th century, which can rapidly manufacture samples or parts according to CAD models. It is a method of material accumulation processing and manufacturing, that is, three-dimensional forming is completed by orderly accumulation of materials. Rapid prototyping technology integrates modern scientific and technological achievements such as CNC technology, material technology, laser technology and CAD technology. It is an important part of modern advanced machining technology. Therefore, it needs a process to digest and absorb foreign advanced technology, cultivate talents, innovate independently, establish brands, and gain user recognition on this basis. According to the current investment method of most state-owned tool enterprises in technological transformation with loans, they often require repayment of the principal and interest within five years, which makes tool enterprises only focus on the conservative and standardized cutting tools with childish market and low risk. The development of modern metal machining is severely restricted by the investment system.
Precision and ultra precision machining is an important part of modern machining manufacturing technology and one of the important indicators to measure the level of a country's high-tech manufacturing industry. Since the 1960s, with the development of computer and information technology, higher requirements have been put forward for manufacturing technology, which requires not only extremely high size, shape and position accuracy, but also extremely high surface quality. It is precisely in this market demand, ultra precision machining technology has been rapid development, a variety of processes, new methods continue to emerge.
The backwardness of metal cutting machining in China is also reflected in the structure of China's metal machining industry. Only a few metal machining companies in China really have the two core technologies of hard alloy metal machining data and coating. Most metal machining plants lack the core technology of hard alloy data. Although some metal machining plants have introduced coating equipment, they do not have the development capability, It restricts the metal machining company to become bigger and stronger.
