TG Series SETTING THE STANDARD IN HELICAL ROTOR AND THREAD GRINDING Holroyd TG Series helical rotor and thread grinding machines have long provided the industry benchmark for high levels of accuracy and efficient stock removal. Extremely versatile, these multipurpose grinding solutions are equally suited to prototyping as they are to batch or volume production. Designed primarily for the finish grinding of helical screw components such as worm screws and rotors, typically after they have been milled to a rough or semi-finished state, TG Series machines can also be used for rough grinding from solid material, if prototypes or low volume production quantities are required. TG Series machines offer production rates and accuracies to suit precise manufacturing strategies. Fully automated on-machine probing provides ‘closed-loop feedback’ of corrections to the wheel dresser and, therefore, does not require a high level of operator skill. The result is extremely accurate profiles. See the TG Series in action at PTG Holroyd on YouTube. www.holroyd.com PTG The first name in precision Holroyd Precision is a member of the Precision Technologies Group (PTG) – an organisation that has established itself at the forefront of high-precision machine tool design, build and supply. The PTG range includes ultra-precision grinding machines for rotor, thread and gear operations; rotor milling machines; heavy duty lathes; deep hole boring machines; friction stir welding machines and special purpose machine tools for the manufacture of precision components.

TG Series TG Series HIGHLY ACCuRATE, DESIGNED fOR SPEED AND HIGHLY CAPAbLE EffICIENCY Uncompromising performance, reliability and efficiency are essential in today’s All TG Series rotor and thread grinding machines are equipped with chucking and production environments. Offering high accuracy and aggressive stock removal work-holding options for quick change tooling and accelerated set-up. A special 3D capabilities, TG Series machines can reduce overall machining requirements and measurement and correction probe optimises production efficiency by maximising provide production rates and accuracies tailored to individual manufacturing accuracy and improving production rates, removing the need for off-machine strategies. Built to Holroyd’s uncompromising standards, TG Series machines inspection. This means that parts can be accurately ground and then measured, with combine robust, reliable performance with advanced production technologies. any deviations being automatically corrected before completion of the cycle.
