Micro tooling system speeds up auto lathe changes
Quick-change tooling system for automatic lathes, featured in the "Micro Machining Tools" catalogue, has achieved time savings of up to 40% and can be used in turning and boring operations.
TiAlN is the highest-performance PVD coating and offers unsurpassed tool life along with unique cutting properties.
The newly designed, ground profile was developed for machining components made of ductile steels and stainless steels.
Drilling operations can be performed with 20% less feed thrust.
Smooth transitions from the extremely sharp cutting edge ensure easy chip removal with less loss in performance.
The entire ground point and in particular the chisel edge are designed for improved centring properties.
Thanks to this improvement, HPM drills can be used for roughing operations at 5xD and high feed rates, still producing drill-holes of excellent quality.
The programme covers diameters ranging from 12.5 to 40mm.
