At the national projects with the support
At the national projects with the support of Tsinghua University and Qiqihar second Machine Tool (Group) Company has successfully jointly developed China's first heavy-duty hybrid machine tool XNZH2430. The machine has a completely independent intellectual property rights of research and core technology is in the "high-grade, sharp" significant numerical control equipment, developed a breakthrough.According to reports, the successful development of the machine to fill China's heavy-duty hybrid machine tool developed in the field blank, for enhancing the structure of China's new heavy-duty CNC equipment design and manufacture capability is of great theoretical significance and practical value.
It is understood that, XNZH2430 heavy-duty hybrid machine tool is a critical foundation for China's manufacturing industry equipment needs, OEM bottled loading water dispenser focusing on high technology and process large and complex turbine blades, propeller blades and other complex parts machining for surface class developed. The machine from software development to hardware manufacturers, not only to meet the above-mentioned parts of the surface machining, but also for military, aerospace, marine, power generation equipment, and mold manufacturing industry, the key to precise parts of the large-scale three-dimensional surface machining.
Parallel Machine Tools (also known as virtual axis machine tool) is the late nineties of the last century the emergence of a new type of structure, machine tools, known as the 21st century, new processing equipment, which overcomes the traditional shortcomings inherent in the structure of serial machine tools, in the same scale ranges , with modular high degree of rigidity is good, moving parts, light weight, acceleration of large, easy to adjust the precision machining and processing high precision, enabling multi-axis CNC machining. The hybrid machine tool are concentrated series of parallel machine tools and machine tools with their respective advantages, these advantages have a parallel machine tool, while machining with the series features a large work space, making hybrid machine tool can be applied in the manufacturing sector continuously.
Precision Instrument, Tsinghua University, Department manufacture of advanced manufacturing equipment, laboratories in the development process of parallel machine tool in China achieved remarkable results, has made dozens of patents and scientific research, in the new structure of machine tool design has accumulated a wealth of experience.
Machine tools, the main part of the increase by two degrees of freedom parallel mechanism composed of a moving table, two columns constitute the Canadian arm of parallel institutions to
spindle box at the same time to connect the arm parallel mechanism, the spindle motor and the milling head, clever design can box, while ensuring high-speed mobile spindle drive smooth transmission chain.Reportedly, the machine control system developed by Tsinghua University VACS6 machine tool control system, this system development based on the linux platform, with high real-time, to meet the fast-axis machining when six real-time control needs. VACS6 control system can also identify the current milling head according to the information automatically load the corresponding control modules, access to the associated user interface, greatly simplifying the procedures.
In order to ensure high-precision processing, the control system can be completed, after calibration of machine tools to easily control algorithms used in machine tool structural parameters be modified to compensate for the current error.The industry believe that, XNZH2430 heavy-duty hybrid machine tool successful development indicates that China has in the heavy-duty high-precision processing equipment, a breakthrough will surely promote China's heavy-duty high-precision machine tool developed by the development of better and faster.
