PTG Holroyd TG Series helical rotor and thread grinding machines have long provided the industry benchmark for accuracy and efficient stock removal.
Extremely versatile, TG Series machines are equally well suited to prototyping as they are to batch and volume production.
Developed primarily for the finish-grinding of helical screw components, such as worm screws and rotors (after they have been milled to a rough or a semi-finished state), TG models offer production rates and extreme accuracies to suit precise manufacturing strategies.
Fully automated on-machine probing provides closed loop feedback of corrections to the wheel dresser, ensuring ‘perfect’ profile generation, without requiring high levels of operator skill.
Available as an option with several of our grinding technologies, HPMS consists of a suite of sub programs for the development of a wide range of helical profiles for screw rotors, vacuum screws and pump screws. HPMS can also be used to assist the control of a profile during the production stages and optimisation of operating meshing conditions.
