US screw compressor manufacturer orders Holroyd rotor grinding machine

1 min read

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."

Holroyd's TG Series of multi-purpose grinding machines are equally suited to prototyping, batch and volume production, but 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. 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. Maximum component diameter from 3mm to 450mm, depending on component profile, and maximum component weight is 500kg.
