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…
The new step that the VGrind 360S has taken is an optional dressing unit for the grinding wheel. After roughing the PcBN cutting edge, the dressing unit ensures that each grinding wheel regains precise concentricity…

Changing the diamond dressing roll
Diamond dressing rolls usually have a bore tolerance field H3. They should only be used on dressing roll mandrels with tolerance field h2 (for the common diameters 52 to 63mm, the…
Figure 4 allows for an initial assessment of the stability of the drilling process due to combined cooling lubrication. It illustrates the range of measured bore diameters for all produced bores (i = 1…300). Once…
