The NC Remanufacturing And Process Application On The Engine Lathe Of Medium-speed Machine Factory In Weichai

The machine tool remanufacturing is a process which can remanufacturabilityassess, disassemble, innovative re-design, re-manufacture and re-assembly to thewaste or old machine tools. It full use of modern advanced manufacturing technology,information technology, NC and automation technology and other high-tech. It is notonly a advanced manufacturing of resource-saving but a green manufacturing ofprotective environment. Compared with new machine tools, the remanufacturing toolswhich have fixed and performance improved reach a new machine factory standardsand have better performance indicators and more function in many areas.The Series products of medium-speed machine Factory in Weichai Group mainlycomprise of stand-alone operations, most of which served years longer with lowerequipment precision stability thus make maintaining the normal operation moredifficult. According to the product positioning and its market factors, themedium-speed machine is not able to update investment in large-scale. To stabilizethe product quality and adapt to product upgrades, we remanufacturing part of thegeneral equipment using advanced technology more than enhanced the level of thetechnology but also meet the purpose of saving resources at the same time. Recently,through the NC remanufacturing and upgrading of technology, innovative design,remanufacturing and re-assembly, the verge of5elimination engine lathe whichprocess crankshaft and flywheel have been restored it’s precision and raised thefunction, and the quality of parts processing have been effectively guaranteed,completing the transformation from manual work to automatic processing.In this paper, we studied the remanufacturing program, machine tools design andmachine tool numerical control processing technology with the method of craftsystem analysis and the comprehensive benefit evaluation analysis, The technology ofradius compensation, constant linear cutting and ceramic coating tool have been usedin processing parts which reflects the good cost performance. Through CNCremanufacturing and numerical control technology research, analysis and processapplications, it provides a method for reference of tool remanufacturing in projectdesign, implementation, function and value implementation. The original latheremanufacturing method implements a function extension, lower investment andgreen manufacturing of remanufacturing.
