combination hard turning + grinding

The process combination hard turning / grinding is used, to great effect, to reduce cycle times. Where the complete hard finishing process (hard turning and grinding) is carried out on a single machine, throughput, transport and storage times can be drastically reduced. There are also advantages in the reduction of setup efforts and setting times.

Turning and Lathe Basics - Stanford University

Turning is one of the most common of metal cutting operations. In turning, a workpiece is rotated about its axis as single-point cutting tools are fed into it, shearing away unwanted material and creating the desired part. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components
