Secondary processing machine tools: most of the key components of the machining process breaks through the traditional machining concept, its high-speed special CNC machine tools also break through the traditional structural design. In a nutshell, its machine tool structure is designed to a variety of high-speed multi-edge special forming tools and machining processes as the leading to meet the entire production line of various machining stations, machining processes, balanced production beat and stable quality and accuracy requirements. In a reciprocating knife process, high-speed machining of engines, crankshafts, various parts are designed and manufactured according to the concept. The machine tool CNC system, quality and accuracy, material properties of parts and other technical parameters, is to the specific technical requirements of each processing station, process, broken down into a single technical indicators, and thus the machine tool structure is relatively simple, stable and reliable CNC system, its processing technology database is solidified in the CNC system.

Throughout the CMT quantitative production line machinery manufacturing process technology, its tool cutting and feeding speed has not reached some of the theory of high-speed cutting concept indicators, but its productivity is in the category of high-speed machining. In production practice, this relatively low-speed cutting more efficient processing technology, through the market competitive environment of the strict test.

Current gaps with foreign countries

For various reasons, some basic common technology research on high-speed machining technology has not been optimized, integrated and popularized for application. Most of the domestic enterprises from foreign countries to introduce high-speed machining technology, of course, there are some gaps.

Parts blank manufacturing technology: the choice of parts blank material, forming process technology optimization, directly affecting the back-order mechanism process, production beat fast and slow and product quality, cost, is the starting point of the full life cycle of the product. Few domestic scientific and technological personnel to make an effort to concentrate on systematic research, foreign rapid prototyping process technology has not really practical in the production process. Fewer people from the green manufacturing, environmental protection point of view to discuss the change and development of parts manufacturing system technology.

High-speed tool technology: the gap is mainly manifested in the research and development of high-performance tool materials (including surface coating materials), tool manufacturing process technology, tool safety technology and tool use technology and other areas.

High-speed machine tool technology: the introduction of technology and equipment in the market economy, driven by China's high-speed machine tool technology has made great progress, the gap lies in the research and development of key functional components of the machine tool, lagging behind the market demand. Such as speed of 20,000 rpm above the high-power high rigidity spindle, brushless toroidal torque motor, linear motors, fast response CNC system, etc. in practical in the blank; multi-functional composite machine tool design, manufacturing network, the application of communication network technology, is still in the primary stage.

Production technology database: domestic manufacturing enterprises (especially state-owned enterprises) generally do not attach importance to the establishment of their own enterprises (industry) production technology system database, which contains manufacturing process and related technology (Know How), metal (non-metal) cutting database, expert mechanism knowledge base, internal and external effective resources database. In addition, the basic common technology research on high-speed cutting mechanism is also in the primary stage.

Trends in high-speed technology for secondary machining

The development of machine tool (equipment) technology is the process of meeting the technological requirements of part accuracy (quality), productivity, production costs, and tool (tool) trajectory. Mechanisms in the field of science and technology, parts (products), tools (tools) and machine tools, the three technological continuum. Therefore, in the discussion of high-speed machining technology, to be a trinity of systematic analysis, investigation; in today's information age, the discussion of high-speed machining technology, inevitably involves information technology, automation technology, business management technology and systems engineering technology. We want to apply high-speed processing technology, must have the above information age, four scientific and technological fields of science and technology basics.

This century in the global integrated manufacturing environment, high-speed machining systems engineering technology is bound to be more widely used in various manufacturing enterprises. Including tool technology: in the manufacturing industry will generally apply high-speed (ultra-high-speed) dry cutting technology; the application of super-hard cutting tool materials, composite (combined) all kinds of high-speed cutting tools (tools) structural design and manufacturing technology, will become a tool (tools) varieties of the development of the leading technology. Ceramics and Ti-based ceramics in the field of faster development, more widely used.

Machine tool technology: With the progress and improvement of CNC system, key functional components, network communication technology, enterprises will promote multi-axis linkage, multi-surface high-speed machining centers, milling, turning functions as one of the composite machining center technology to achieve practicality; corresponding to the emergence of various types of CNC special high-efficiency processing machine tools; will be more widely used in laser technology in the field of mechanical forming and processing, cutting and processing; CNC machine tool functions will be able to Implementation of networked communication and production, and further enhance the utilization of CNC machine tools.
