  • Mill Speed - Critical Speed

    Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

  • Speeds and Feeds 101 - In The Loupe

    Spindle Speed Cap . As shown above, the cutter speed (RPM) is defined by the SFM (based on material) and the cutter diameter. With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example, a .047" cutter in 6061 aluminum (SFM 1,000) would return a speed of ~81,000 RPM.
