NUM and Chinese partnership develop machining centre
CNC specialist NUM has helped the Chinese machine building company Original Point Machine Tools (OPMT) to develop an advanced 8-axis CNC machining centre capable of processing many different types of materials, including metal, ceramics, glass and cemented carbide. OPMT is a relatively small but fast-growing company based in Fo’shan – of Guangdong Province – in south China. It is rapidly acquiring a reputation for innovative complex engineering: after developing a highly successful 4-axis milling centre for an automotive production line, it then created a compact 5-axis milling station for the dental industry. For its latest project, OPMT was asked by Guangdong University of Technology to develop a machining centre that combined high speed laser cutting and milling capabilities. This key provincial university is located in Guangzhou, Guangdong Province, China, and provides a wide range of courses, with a major emphasis on engineering. OPMT chose to partner with NUM for its CNC expertise and with the Xi’an Zhongke Microcrystalline Manufacturing Company and the Chinese Academy of Sciences to help with some of the complex materials processing issues. The result is the ML125 8-axis multi-function machining centre. The machine has a dual laser head that is capable of switching between a 20 watt picosecond laser for very high speed cutting and an ultrafast 10 watt femtosecond laser for improved process quality. The femtosecond laser is capable of drilling and cutting almost any type of material, and its very short 1030 nm wavelength means that it is suitable for micro/nano processing applications. Entirely controlled by NUM’s latest-generation Flexium+ 68 CNC platform, the ML125 machining centre has eight servo axes, two independent NC channels and fast application-specific I/Os embedded in the NCK hardware. Movement of the fully articulated laser head is controlled by five NUMDrive X servo drives, with high speed interpolation between all five […]
