Leading USA-based Screw Compressor Manufacturer Places £1.3m Order With Holroyd Precision Limited

In an order valued at £1.3 million, Precision Technologies Group company, Holroyd Precision Limited, is to supply one of its advanced helical rotor and thread grinding machine tools to one of North America’s leading screw compressor manufacturers.

The machine, a Holroyd TG 350, will be delivered later this year and will be used to precision-grind screw rotors for use in industrial refrigeration technologies.“Although we are not allowed to name this customer for commercially sensitive reasons, we can reveal that they are part of a multi-billion-dollar global manufacturing organisation and specialise in gas compression technologies,” comments Holroyd Precision’s Sales Director, Steven Benn.

“Needless to say,” he adds, “we are delighted to have secured this important order from them – especially as although we faced considerable competition during the tendering stages, we were recognised for the uncompromising standards that our technologies offer.”

TG Series: providing the industry standard

Holroyd’s TG Series of multi-purpose grinding machines has long set the industry benchmark for high levels of accuracy and efficient stock removal. Equally suited to prototyping, batch and volume production, TG Series machines are designed primarily for the finish grinding of helical screw components such as worm screws and rotors after they have been milled to a rough or semi-finished state. TG models offer production rates and accuracies to suit precise manufacturing strategies. Fully automated on-machine probing provides closed loop feedback of corrections to the dresser wheel and does not require a high level of operator skill.

TG Series grinding machines, at-a-glance:

·         Accelerated and simplified set-up

·         Fully automated grinding wheel balancing system

·         Powerful, menu-driven touch screen programming

·         Unique on-board Holroyd 3D CMM component scanning probe

·         High-power, high-speed grinding spindles

·         Optional hollow spindle for longer components

·         Advanced in-process dressing systems

·         Large diameter grinding wheels, for maximum wheel life

·         Optional Holroyd Profile Management System for profile development and control

·         Maximum component diameter from 3mm to 450mm, depending on component profile

·         Maximum component weight 500kg
