When the depth of cut is lowered, feed rate can be increased further. 2. If the machine is not suited to the recommended spindle speed, please use the maximum spindle speed available. In this case, lower the feed rate by the same ratio. 3. If cutting noise and vibration occur, please reduce the cutting conditions accordingly. pf Radius Milling Medium Hardened Steel Hardened Steel Hardened Steel Hardened Steel Work Material Pre-hardened Steel, Die Steel SKD61 SKD11 SKH55 Cutting Conditions (40 to 50HRC)Spindle SpeedFeed Rate (50 to 55HRC)Spindle Speed Feed Rate (55 to 60HRC)Spindle SpeedFeed Rate (60 to 65HRC)Spindle SpeedFeed Rate RE (mm) (min -1) (mm/min) (min -1) (mm/min) (min -1) (mm/min) (min -1) (mm/min) 0.20 50,000 500 50,000 500 50,000 500 50,000 500 0.30 50,000 800 50,000 800 50,000 800 50,000 700 0.50 50,000 1,400 50,000 1,400 50,000 1,300 42,000 1,000 0.75 50,000 2,000 50,000 2,000 37,300 1,400 28,000 1,000 1.00 38,100 2,100 38,100 2,100 28,000 1,400 21,000 1,000 1.25 30,500 2,100 30,500 2,100 22,400 1,400 16,800 1,000 1.50 25,400 2,100 25,400 2,100 18,700 1,400 14,000 1,000 2.00 19,100 2,100 19,100 2,100 14,000 1,400 10,500 1,000 2.50 15,300 2,100 15,300 2,100 11,200 1,400 8,400 1,000 3.00 12,700 2,100 12,700 2,100 9,300 1,400 7,000 1,000 4.00 9,500 2,100 9,500 2,100 7,000 1,400 5,300 1,000 5.00 7,600 2,100 7,600 2,100 5,600 1,400 4,200 1,000 6.00 6,400 2,100 6,400 2,100 4,700 1,400 3,500 1,000 Standard ap 0.08DC 0.05DC Depth of Cut pf 0.25DC 0.15DC I132
