Grinding technology development trend
Grinding machining is important processing technology in mechanical manufacturing.cnc grinding With precision mechanical products, the requirement of increasing the reliability and service life, high hardness, high strength, high wear resistance, high functional new materials application increased, for grinding processing and put forward many new problems, such as material of grinding machining and surface integrity, super precision grinding and high efficiency grinding and grinding automation, etc. Problems to be solved.At present, the grinding technology is moving toward using super hard abrasives, development of precision and ultra precision grinding, high speed, high efficiency grinding technology and the development of high precision, high stiffness of the grinding machine automation direction.
One. In-depth development of grinding theory and technology research
Grinding theory research is the basis for the development of grinding technology, cnc grinding the grinding technology and the development of practice and research provides the opportunity for grinding theory, requirement and new topic, in recent ten years, professionals engaged in the work of grinding, grinding technology and phenomenon many factors for a lot of in-depth research and achieved fruitful results.
Two. Unit grinding machine high speed, high precision components manufacturing technology
High precision grinding machine spindle unit, feeding unit, bearing unit and auxiliary unit is the key parts and components. Spindle unit including spindle power, shaft, bearing, and frame sections, she affects the precision of the machining system, stability and application scope, its dynamic performance and stability of high performance precision ultra-precision grinding, play a key role. Feed unit including the position detection unit, Demand of feed units, therefore, flexible operation, high resolution, high positioning accuracy, not crawl and large movement range, both to have larger acceleration, and large enough thrust, high stiffness, cnc grinding quick dynamic response, high positioning accuracy. Machine tools supporting technology mainly refers to the supporting member of design and manufacturing technology. Auxiliary unit technology including fast clamping workpiece, high efficiency grinding fluid filtration system, machine safety devices, chip removal and the workpiece cleaning technology, spindle and grinding wheel dynamic balance technology, etc.
