摘要
In the automotive and aerospace industries, advances in workpieces materials as well as the constant drive for increased productivity in the manufacture of components from existing materials place increasing demands on the abrasive tooling used and ultimately the abrasives selected.In response to these demands, a new stronger and sharper CBN abrasive, ABN800A, has been developed for vitrified bond tools.Its increased performance is demonstrated in creep feed grinding studies on cast iron and nickel based super alloys.In cast iron grinding, a 23% increase in the G-ratio is observed,while in grinding of Inconel 718 a 10% reduction in the grinding forces is demonstrated-in both cases,the performance is measured relative to the leading CBN abrasives in the market ABN800.ABN800A is expected to find applications in the manufacture of aerospace gas turbine components such as vanes,blades, nozzles and seals and in automotive tooling for engine and drive train components such as camshafts, crankshafts, gears, valves, drive shafts and CVjoints, as well as for other tools for grinding hardened ferrous metals and super alloys.
