Based On WS450-6x5000CNC MONOLITH Roll Grinder Of Efficient Grinding Process Research

High quality metal plate, belt, foil production, especially the Shougang Corporation cold rolling tandem mill strip production, to a large extent dependent on the quality of the roll. As a result of roll in rolling process by high temperature oxidation and mechanical wear and other reasons, led to roll the geometric accuracy of the surface damage and has certain thickness fatigue layer, and require periodic on roll grinding roll repair, these precision quality through precision roll grinder and fine grinding technology.Recently, with the company of Shougang cold rolling mill production and production of roll grinder, grinding efficiency and technology requirements are also more and more high, the Shougang cold rolling work roll grinding company Deparent of the largest diameter up to1300mm, the maximum weight of up to26t, the desired geometric accuracy of micron order, roll the form and position tolerances (eccentric, roundness, runout, taper) more stringent, roller type tolerance is smaller,on roll detection technology requirement taller, more comprehensive (size, hardness, roughness, testing). Faced with increasingly fierce competition in the cold rolled sheet market,how to improve the roll grinder grinding quality becomes the Shougang Corporation to improve product quality, increase productivity, reduce the cost of key factors.This topic from the study of grinding performance characteristic proceed with, analysis of the impact of roller grinding quality of a variety of factors, and Shougang cold rolling mill company used between the German WS450-6x5000CNC MONOLITH type high precision roll grinder as a specific object of study, aiming at Shougang Corporation cold strip mill roll condition, put forward reasonable convenient, high quality roller grinding processing method, in order to make future roll grinding process, can in a shorter period of time to get more high roller grinding quality, the specific research contents are as follows:(1) WS450-6x5000CNC MONOLITH roll grinder grinding machine as the research object, analysis of main structure and function, for grinding quality can provide basic hardware; (2) WS450-6x5000CNC MONOLITH roll grinding machine as the research object, analysis of grinder curve programming and programming technology, to provide software based implementation of grinding quality;(3) according to the work roll/intermediate roll design requirements and technical requirements of grinding, grinding roller shape precision and surface quality and its influencing factors analysis;(4) in the grinding of roll shape precision and surface quality on the basis of the analysis, put forward the work roll/intermediate roll grinding optimization measures for improvement, effectiveness evaluation.
