Milling (machining)

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

Getting a Hold on Shaft Collars: Choosing the Correct

Maintaining close tolerances between the shaft, hub, and collar and keeping hub thickness as small as possible helps minimize the amount of force lost on the hub itself. Several design and manufacturing features such as bore size and concentricity, influence the holding power of clamp-style shaft collars.
