PTM Face Drivers are best used in the mass production of parts since they make it possible to reduce the clamping times in the various turning operations. Their extremely compact shape allows excellent approach of the tool to the workplace. They ensure safe driving even for parts that are not perfectly square cut. When the extended point is fitted it is also possible to machine shafts which have holes in the center.

We also offer custom centers to meet our customers’ specific requirements, with quick turnaround and very reasonable prices. PTM can hold tolerances that the competition can’t.
