Thanks to technologies supplied by Rochdale-based Holroyd Precision Ltd (www.ptgltd.com), a major industrial group in Northern China will soon embark on the production of its own range of ‘air ends’, helical rotors and screw compressors.

In an order secured last month (and worth more than £1.4 million), Holroyd Precision is to supply one of its helical rotor and thread grinding machines to the Chinese organisation.

The Holroyd TG 350E will be delivered in early 2019 and will be used by the customer to precision-grind helical components up to 350mm in diameter and 1,795mm long.

Holroyd regional sales director Steven Ben said: “We are delighted to have secured this significant order; and although we cannot name the customer for commercial reasons, it is particularly rewarding to know that it recognised the distinct benefits that our technologies offer.

"Moreover, as we are members of the Manchester-China Forum, securing this significant order also underpins our on-going drive to strengthen ties between the city region and China.”

Holroyd’s TG series of multi-purpose grinding machines starts with the TG 50E — a machine designed to precision-grind components up to 50mm in diameter and 610mm long, with models offering stepped increases in capability up to the production of helical components measuring 350mm in diameter and 2,020mm long.

Equally suited to prototyping, batch production 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.
