Spindle Speed Calculation

• This table is a guideline for selecting cutting parameters; adjust them as needed according to the machine and workpiece conditions • For blind holes; adjust the parameters by observing the chip evacuation • Cermet T1500A is recommended for good surface finish for light roughing of steel • AC830P is recommended for interrupted cutting of steel • AC820P is recommended for interrupted cutting of ductile cast iron • For step cutting; it is recommended to increase the depth of cut by 1.6 times and reduce the feed rate by 60%

N: Spindle Speed SFM: Cutting Speed D: Diameter

N = SFM x 3.82 / D
