1 High-performance roughing even at deep cutting depths Smooth operation and high metal removal rate HPC milling in tough, low-alloyed and high-alloyed steels, and other difficult-to-machine materials GUHRING - YOUR WORLD-WIDE PARTNER

2 in application series mm on machine component Application: HPC roughing; dry machining in 4140 (28 HRc) steel in HPC clamping chuck with PinLock collet for pull-out prevention Cutting parameters: DOC (a p ): 2.36 WOC (a e ): up to.040 SFM: 885 RPM: 4300 IPT:.0083 IPM: up to 146 Metal removal rate Q = 13.8 in 3 /min Tool life 278 minutes for roughing operations! 2

3 HPC milling in steels, stainless steels, and Ni & Ti alloys stable cutting edge at corner thanks to corner protection chamfer and lip correction at face = Double Protection! optimized flute geometry deepened flute (stepped core) on front portion of tool for improved chip evacuation 48º helix angle with unequal flute spacing for soft, quiet cut Chip breakers in the cutting edge of the extra length tools ensure short chips for more efficient chip evacuation. This allows for higher metal removal rates with less load on the machine. Face geometry with large chip gullets and improved web thinning for minimum vibration during plunging, ramping, and helical interpolation. Chip formation using a conventional end mill (left) versus the (right). 3
