A l’inverse, tous les outils utilisés jusqu’à présent pour cet usinage nécessitent des réglages qui prennent du temps lors des changements de plaquettes de coupe. Il fallait également régler le faux-rond radial sur la partie de l’outil usinant les guides de soupape.

Conversely, all the tools previously used for this machining task require to some extent time-consuming setting work on an insert change. Also it was normally necessary to set the radial run-out on the replacement of the valve guide reamers mounted in the base tool. In the new MAPAL concept the tool for machining the valve guide is now connected using the proven HFS connection. The tool is changed with a radial run-out accuracy of < 5 µm by simply screwing in or unscrewing. This very stable connection also makes it possible to increase the feed rate.
