Longitudinal turning

Turning process where lathe centers hold a cylindrical workpiece which is fed through the chuck.

The process

The workpiece in the form of a rod is fed out by a chuck [1] which fixes the workpiece vertically and laterally. The guiding chuck allows the workpiece to be moved axially during the processing time. The tool holder [2] control turning tools with fixed or interchangeable inserts that removes material through chip breaking for creating a rotationally symmetrical detail.

The tool is placed as close as possible to the chuck and maintains this position during the machining process. The workpiece is positioned and supported by a lathe center that moves along with the axial movement of the rod.
