Leader in air conditioning systems selects new ‘larger capacity’ Holroyd rotor grinding machine

TG 350 rotor grinding machine

One of the world’s leading manufacturers of air-conditioning systems has ordered an advanced helical rotor and thread grinding machine from Rochdale-based Holroyd Precision.

The machine – a Holroyd TG 350E-XL – will be shipped to China later this year, where it will be used by the air conditioning technologies specialist to produce air ends, helical rotors and screw compressors for use in industrial cooling systems.

This will be the second Holroyd TG 350E rotor grinder to be purchased by the organisation in recent years.

Due to an ingenious solution by Holroyd’s design engineers, the TG 350E-XL’s extra-large traverse capability offers larger capacity rotor lengths than can be accommodated on a ‘standard’ TG 350E, offering greater manufacturing flexibility.

The TG 350E-XL is particularly suited to environments where there is a requirement to vary production to longer rotor lengths, or where factory floorspace is at a premium.

Typically, rotors produced on a TG 350E-XL will have longer shafts as used in semi-hermetic compressors with direct drive motors. Alternatively, the rotor body length might be longer to provide increased air or refrigerant capacity within the compressor.

Compared to a standard TG 350E, which can be used to produce rotors of up to 350 mm in diameter and 1795 mm in length, the XL variant of the machine enables components of up to 2026 mm in length to be manufactured.

Holroyd Regional Sales Director, Steven Benn, said: “Securing this major machine tool order – worth in excess of £1.3 million to our UK manufacturing facility – was particularly pleasing.

“In the face of stiff competition, we were chosen for our ability to provide the precise rotor grinding technology that the customer required, all supported by the high levels of performance and repeatability that they have come to expect from our ultra-precise grinding technologies.”

With production facilities in the UK, USA and China, Holroyd Precision Rotors manufactures the special purpose, ultra-precision helical components used in a wide range of industries, including refrigeration, air-conditioning, gas and vacuum pumping, industrial air handling, aerospace, medical equipment, power transmission, and oil and gas.
