Description:

Claim:

This invention relates to tracer valves for hydraulically controlled machine tools, such as lathes, which are used in the production of duplicate Workpieces in an automatic manner. A tracer valve of this character is provided with a stylus arranged to trace the profile of a pattern or template and is interconnected in a hydraulic power circuit arranged to shift the cutting tool in a path which corresponds to the template prole, thereby to reproduce successive Workpieces according to the template profile.
