How to Obtain Rolling Torque? | Metals | Metallurgy

The mill is driven by a motor which runs at 950 rpm and power is transmitted through a reduction gear box and a pinion box. The efficiency of gear box is 0.8 and of pinion box is 0.98. The co-efficient of friction in bearing = 0.06 and roll neck diameter = 360 mm. Determine the motor power required.

Cutting Speeds & RPM Calculations

The RPM formula for tapping is no different from the other formula we have been using, but the consideration mentioned for tapping must be made before we actually do any power tapping. Until you know how the tap will operate under your conditions, start with 1/3 to 1/2 the calculated RPM and gradually increase the RPM to the capacity of the conditions.
