GENIS - External cylindrical grinding with vitrified bonded high-performance grinding tools The demands on modern automotive engine and gearbox producers continue to increase. The additional requirements create capacity bottlenecks, and an increased demand for more efficient grinding solutions. TYROLIT faces this challenge in external cylindrical grinding with a new generation of vitrified bonded CBN high performance grinding tools. After intensive research, TYROLIT has succeeded in developing GENIS, a new bond system that makes it possible to guarantee optimal wetting of the CBN grain even with...

GENIS application example camshaft Results Finishing of the cam profile Material Schaudt ZEUS Surface speed Cooling lubricant Due to the need to increase the service life of the grinding tool significantly, at first the production planners from the customer worked in partnership with Tyrolit engineers to analyse the process requirements. The new bond system of the GENIS product line was then selected as well as the use of a particularly free-cutting CBN grain. Through the optimized bond properties, it was possible to increase the number of grooves per dress cycle from 120 to 190. In addition...

GENIS application example crankshaft Grinding in the main and pin bearing 42CrMo4 54 - 58 HRC Junker JUCRANK Surface speed Cooling lubricant Increase of the tool life by approx. 40% A change to the material used by the customer, as well as a significant increase in the stock to be removed on the bearing surfaces, presented a very special challenge to both the user and the TYROLIT application engineers. After a detailed analysis of the process, a grinding tool was selected from the GENIS product line with a new, especially free-cutting CBN grain quality. The process parameters were changed accordingly...

GENIS application example gear shaft Results Junker Quickpoint Surface speed Cooling lubricant Increase of the tool life by 20% Customer requirement: Prevention of hidden grinding burns as well as simultaneous increase of the tool life. After a detailed analysis that took into account all influencing factors of the process, the rough grinding zone angle of the tool was redesigned. It was then possible to select a tool from the GENIS product line with a specification of extremely high edge stability with which the overlay rate during grinding could be redefined. After optimization of all process...
