Thread Cutting on CNC Lathes

Author: Kam Wire E.D.M. Technologies Inc. and Kam-Medical | | Categories: CNC Machining

The method of thread cutting on CNC lathes is called single point threading using an indexable threading insert. As a threading operation is both a cutting and a forming operation, the shape and size of the threading insert must correspond to the shape and size of the finished thread. By definition, a single point threading is a machining process of cutting a helical groove of a specific shape with a uniform advancement per spindle revolution. The uniformity of the thread is controlled by the programmed feed rate in feed rate per revolution. Feed rate for threading is always the lead of the thread, never the pitch. For single start threads, the lead and the pitch are identical. As single point threading is a multi-pass operation, the CNC system provides spindle synchronization for each threading pass.
