Milling Speed and Feed Calculator

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material. Learn more about Milling. Milling Speed and

Common ball screw terms explained

A ball circuit is a closed path of recirculating balls. "Turns" refers to the number of trips the balls make around the screw shaft before being recirculated. The relationship between circuits and turns is influenced by the recirculation method. Ball returns that use the deflector or thread-to-thread (aka cross-over) method recirculate each turn of balls individually. Therefore, the number

Powder metallurgy – basics applications

Vibratory Ball Mill. R. Ganesh Narayanan, IITG Attrition mill : IN this case, the charge is ground to fine size by the action of a vertical shaft with side arms attached to it. The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 40

How to determine if a screw will back drive

Lead screws and ball screws have different tendencies to back drive—lead screws typically have a very low chance of back driving, whereas ball screws are more likely to allow the load to fall. This disparity comes down to efficiency. A lead screw's low efficiency, which is often considered a negative performance factor, can, in a vertical application, prevent the nut from freely rotating
