The RayCutter systems enable the efficient machining of up to 200 indexable inserts in a single clamping operation, without the need for additional automation or further user intervention. Particularly…
Voith Turbo has switched the 24/7 roughing of the transmission housings to NAWA's hpcCUT series with brazed PCD cutting edges. Since then, shorter cycle times have been achieved in Garching and tool costs have been…
Issue with Regrinding Ultra-Hard Cutting Materials
One reason why reground indexable inserts do not achieve the same tool life as new tools is that only the visibly detectable wear is considered for…
Compared to purely cohesive bonding, the mechanical strength of the grinding layer was increased by 363% due to the improved bonding of the diamonds. Performance tests in deep groove grinding of carbide showed a…
