Multi-Spindle Screw Machines

The multi-spindle screw machine is turning machine that allows multiple tools to cut multiple pieces of material simultaneously. Like a Gatling gun, the multiple spindles are carried in a precision machined drum that typically rotates in a horizontal orientation. The total number of operations needed to complete a part are divided among the number of spindles, so that a part is completed with one full rotation of the drum. However, because multiple parts are being machined simultaneously, a part is completed each time the drum indexes, making for a very efficient process. Usually configured in 4, 5, 6 or 8 spindle models, each spindle is attacked by a cross-slide and end-slide tool effectively making each spindle a 2-axis lathe.

A Collaborative Approach to Custom Machine Design

Conventional wisdom says multi-spindles equal high volume. That’s not necessarily true, as this U.K. project demonstrates.
