Milling in steels with hardness above 55 HRcThis strategy of milling in hardened steels is used because, when using theright setup and circumstances, this saves production time compared to EDM.Advantages:1. No EDM is required(milling is much faster)2. Polishing can beminimized3. One single clamping,so it is easier to achieveaccurate resultsBoth development in milling machines and cutting tools have made it possibleto use this revolutionary strategy. This is possible due to new carbide grades,improved cutting geometries and new coating developments.Several strategies are possibleHPM (High Perfomance Machining)HSM (High Speed Machining)- High cutting speed (Vc)- High cutting speed (Vc)- Large cutting depth (Ap)- Small cutting depth (Ap)- Small cutting width (Ae)- Small cutting width (Ae)- Medium feed per tooth (Fz)/ table feed (Vf) - High feed per tooth (Fz) / table feed (Vf)Depending on the workpiece different strategies can be chosen.Chip removal and coolant in such applications are crucial.Tips:- Use a rigid milling machine andclamping method.- Try to minimize entering and exitingthe workpiece.- Use minimum lubrication or oil-mistspray.Old vs New generationEndmill: VHPK206006406L070, Ø6,0v cnF zv fa pa eCoolant280 m/min15.000 rpm0,25 mm/t7500 mm/min0,4 mm1,5 mmmin. lubricationToollifeOld generationCompetitorNew generation60 50 100 150 200 250 300
New generation ballnose endmillfor milling hardened steels up to 70 HRcSmooth surface finish, accurate tolerances and precision are essential featureswhen milling hardened steels. The combination of special developed carbide,coating and new developed geometry of the VHPK includes these features.The VHPK offers excellent performance, much longer toollife and moreprecision. Numerous in-house tests and customers’ feedback have proven theoutstanding performance of this new development.New designed ballnosegeometry for finishingapplications.Mirror finish for longertoollife and highprecision.Carbide with ultra finegrain structure of 0,3-0,5micron and high tensilestrength.Coating- Multi layer coating- Nano structure- Extreme hardness- Longer toollife± 0,005 mmHigh precisionballnose profile.7
