How to Calculate Dynamic Load

Define the application for calculating dynamic load; the weigh scale on an elevator is a good method in which to do so. A 150-pound adult standing on a scale on an elevator at ground level notes their 150-pound reading as they push the button for the 20th floor.Get price

Milling Step

In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.Get price

Testing method for ball mills

The Bond ball mill test is designed to predict power in wet ball mill grinding circuit operating at a 250% circulating load. However, moving away from this condition reduces the accuracy of the test. Further, the Bond ball mill test does not predict the behavior of large rocks in a grinding circuit where the mode of breakage is impact dominated.Get price

Lead screw sizing in 4 steps

In horizontal applications, where the load is supported by a low-friction linear guide, the weight of the moved load contributes only a small amount to the axial load on the screw. But in vertical applications, where gravity causes the screw shaft to see the full force of the load, buckling can become a significant factor in lead screw sizing.Get price

How to determine if a screw will back drive

But if the application requires a ball screw for positioning accuracy, load capacity, or rigidity, there is a way for designers to determine the likelihood that back driving will occur. First, calculate the back drive torque, which is a factor of the load, the screw lead, and the screw efficiency: T b = back driving torque (Nm) F = axial load (N)Get price
