• how do you get the cutting parameters right for small end

Jul 24, 2009 · I struggle with the speeds and feed rates for "small" ball end mills (0.03125, 0.040, 0.0625) when cutting our typical tool steels such as P-20, A2, and H13. We are limited to a maximum spindle speed of 15,000 rpm. Do you concentrate on the sfm for finish end mills of the same diameter, or do you consider that the center of the ball is going to push harder for a given feed per tooth?

• what factors will influence ball mill grinding efficiency?

Mar 26, 2021 · When the feed rate is very low, the amount of ore in the ball mill is small, not only the productivity is low, but also the formation of empty beating, causing serious wear and over-grinding. In order to improve the ball mill grinding efficiency, a proper feed rate should be maintained so as to maintain a large amount of ore to be ground in the ball mill

Example: Using the same criteria as the spindle speed calculation, RPM = 6037; from the chart, chip thickness is 0.005", and all of our ball nose finishers have 2 flutes. i.e.- 6037 x 0.005 x 2 = 60.37 IPM; Your FEEDRATE (inches per minute) can be calculated by the formula: RPM x chip thickness x # of flutes. Calculate De = Effective Cutting Diameter

Jun 26, 2017 · Ball Nose Milling Without a Tilt Angle. Ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements.To properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life and part finish, follow the 2-step process below (see Figure 1)
