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.
