End mill milling tool MRBSH330

solidfinishingfor hardened steel

MUGEN COATING PREMIUM Plus with high oxidation resistance and abrasion resistance is suitable for machining above 60HRC. Demonstrates same performance with MUGEN COATING PREMIUM even on machining 45〜60HRC. Comparison with other tool brand HAP40（64HRC） Cutting condition: n=20,000min-1, vf=1,600mm/min, ap 0.15 × ae 0.3mm, Coolant: Oil Mist ● High-efficiency 3-flute ball end mill optimizes a shape of central edge and enables high depth of cutting. ● Even hardened steel of 45 to 70HRC can be machining with long tool life and high efficiency. ● R accuracy is ±0.005mm (R accuracy is based on a half value of actual diameter). ● Shank diameter tolerance , high accuracy type, is - 0.001 ～ - 0.003. ２－１. Minimized center ball shape reduces cutting load to enable high depth of cut. ２－２. Optimized chip pocket design realizes smooth chip removal. ２－３. Sharp cutting edge with reduced cutting load and material with fracture resistance realizes long tool life and high precision for hardened steel　 ２－４. Unequal flute prevent chattering Comparison with other tool brand on roughing process 【Under the same rate of depth of cut ap 0.23 × ae 0.3 mm】 ・Work Material：HAP40 (64HRC) ・Spindle speed : 20,000 min-1 ・Feed：2,400mm/min
