excell sheet calculation torque speed power for rolling mill

  • POWER IN ROLLING

    POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.The total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance 'a' from the line of centers of the rolls.

  • Understanding CNC Torque vs Horsepower

    Old School End Mills Traditionally, a larger diameter 1" end mill would require high torque and low speed (SFM /RPM), while a 1/4" diameter end mill would require low torque and high speed (SFM / RPM). Generally, different end mill diameters geometries have different requirements for both horsepower and torque.
