GBP 57 DIN ISO G 6.3 6357 7388-1 8000 HPC min-1 Face mill arbors, vibration-damped − DIN ISO 7388-1 (formerly DIN 69871) ■ Taper shank, spigot, and all contact surfaces are ground at the collar. ■ With RFID / Balluffchip bore. ■ Larger collar contact face. Supplied with: Cutter lock screw and drive dog. Optional extras: Pull studs (PS) No. 308600 − 308806, PS wrenches No. 308820 – 308835, Special toggle spanner No. 309840. 30 1104 Milling cutter lock screws No. 309860; 309861. Note: Further sizes on request. Through-coolant holes Fine machined surface resistant to corrosion. d High-performance version with embedded heavy metal core ​ n -dampe Vibratio Advantage: The heavy metal core specially matched to the arbors gives optimum ≤5µm Infeed fz [mm] machining results even with long overhangs: GARANT High Performance ■ Saves time, because allows use of the maximum machining parameters. ■ Smooth running and thus perfect surface quality results. Standard ■ Saves costs, because tool life is increased. Form AD ■ Less vibrational stress on the machine headstock. Note: Balance quality G 6.3 dependent on the maximum operating speed.
