 | Hard machining for any field of application requires demanding, customer tailored cutting solutions. Mikron Tool accepts the challenge and offers with CrazyDrill Cool an exceptional tool for the high precision machining of hard materials.
Example: Tests on a Mikron VCP 600 machining center with a drill Ø 2.15 mm and a depth of 10 x Ø in 90MnCrV8 (W.Nbr. 1.2842) with a hardness of 60 HRc have shown a perfect surface quality as well as accuracy. At first, with the CrazyDrill Pilot a hole to a depth of 2 x Ø has been drilled. The subsequent hole has been done with a CrazyDrill Cool at a cutting speed of v = 30 m/min and a feed rate of f = 0.03 mm/rpm. Two pecking cycles have been included, the first one at 5 x Ø and the second one at 8 x Ø. A total of 300 holes have been made.
