PTG Holroyd EX Series rotor and pump-screw milling machines have earned global acclaim for their high speed, high precision and unrivalled build quality. Delivering class-leading performance and reliability, ‘standard build’ EX machines can cut rotor or worm helix profiles in blanks of up to 850 mm in diameter.
Where this diameter is too small, we offer a custom-built 10EX model that can complete the same milling functions on blanks greater than 1000 mm in diameter.
Custom-build options are also available for customers whose requirements differ from the capabilities of our standard build machines.
Immensely flexible in their manufacturing capabilities, EX Series machines are equally efficient when producing highly complex components with helical screw profiles as they are when being used to mill gear parts such as worm shafts.
All EX Series rotor and pump-screw milling machines deliver the same class-leading performance, reliability and repeatability, and benefit from our advanced technologies such as on-machine probing and dry milling techniques for certain materials.
