Get PriceThe basic equation used to calculate the proper RPM for machining is as follows: RPM = (cutting speed x 12)/(pi x diameter) Where the cutting speed is in feet/min and the diameter is in inches. This can be approximated as: RPM = ( x cutting speed)/diameter. In order to use the equation, four pieces of information are required: 1.
Get PriceRPM = The rated spindle speed in Revolutions Per Minute D = The diameter of work in inches. FIGURE 10Formula for adjusting spindle speed for cutting a given diameter. NOTE: To estimate RPM, remember that the speed range of your vertical mill is from 0 to 2800 RPM. (The lowest usable speed is about 70 RPM, so we use that in our specifications.
Get PriceJan 05, 2018· If you are using carbide inserts for threading, cutting speed can be around 50 meters per minute. So RPM = 1000 x Cutting speed ÷ (pi x diameter) = 1000 × 50 ÷ ( × 42). In threading, Feed per revolution= pitch of the thread = mm/ rev
