PREMIUM QUALITY AMERICAN-MADE CUTTING TOOLS Technical Information
VI-PRO CARBIDE END MILLS
• Running at higher SFM; heavier chip loads than conventional end mills • Speed and feed chart parameters are for 4 flute full diameter slotting • Slotting depth up to 1 x diameter • Tool holding important for maximizing tool life. Minimize TIR • Max ramp angle recommended 3º or less
Speed and Feed Calculation: RPM = (3.82 x SFM) ÷ Dia. IPR = IPM ÷ RPM SFM = (RPM x Dia.) ÷ 3.82
IPM = IPT(chip load) x No. of Teeth x RPM IPT(chip load) = IPM ÷ (No. of teeth x RPM)
Benefits of Post polishing ALCRO-MAX by nature of the coating process leaves tiny “droplets”of the coating on the surface of the tool. Proven results have shown that the removal of these droplets provide a smoother tool surface which results in a better cut. Perhaps the most important benefit, is that the tool is able to run at faster feed rates due to the smoothness of the flute area. This results in better chip evacuation and cooler temperatures resulting in longer tool life.
