One of China’s leading manufacturers of air compressors has once again demonstrated its confidence in the ultra-precise technologies offered by Rochdale-based Holroyd Precision Ltd (www.ptgltd.com).

Only last year, the Chinese company bought one of Holroyd Precision’s Zenith 400 helical profile grinders. Now, just over 12 months later, it has returned to Holroyd for an 8EX rotor-milling machine and a CS700E tool management centre.

Newly developed, the CS700E machine has been designed for grinding high-accuracy profile forms on finish-milling cutters up to 700mm in diameter. Scheduled for shipping in March 2019, the combined order is valued at “several million pounds”.

Holroyd Precision’s regional sales director, Steven Benn, said: “Our EX-series rotor-milling machines have earned global acclaim for their high speed, high levels of precision and unrivalled build quality.

“The 8EX model, as chosen by this customer, represents a new generation of high-capacity rotor-milling machine that accommodates particularly deep helical profiles; and by also purchasing the CS700E, the customer will benefit from unprecedented control of the profile forms they produce.

“The accuracy of any helical screw form relates directly to the accuracy of the cutting tool that is used to create it.

“With the CS700E, we are enabling manufacturers of larger helical components to achieve even greater levels of accuracy and repeatability, by benefitting from complete control of all aspects of the cutting tools they use.

“The CS700E produces high-accuracy profile forms on a wide range of tool materials, from traditional high-speed steel to exotic materials such as carbide and cermet finish-machining systems.”
