North American compressor manufacturer chooses second Rochdale-built PTG Holroyd rotor grinding machine

TG350 rotor grinder

One of North America’s premier rotary screw compressor manufacturers has ordered a new, ultra-precise TG 350E CNC rotor grinding machine from Rochdale-based PTG Holroyd.

The machine will be used alongside a previous generation TG 350 model that has been in reliable daily operation at the compressor rotor manufacturing facility since 2008.

Valued in excess of $1.7 million, the new TG 350E rotor grinder is currently in build at PTG Holroyd’s Rochdale technology centre and is scheduled to ship in springtime 2023.

It will be used by the customer to precision-grind screw rotors of up to 350 mm in diameter and 1800 mm in length and will bring even higher levels of flexibility to the company’s manufacturing strategies.

PTG Holroyd Sales Director, Mark Curran said: “Around the globe, PTG Holroyd’s rotor milling, rotor grinding and gear grinding machines are renowned for their accuracy, reliability and longevity.

“New TG Series models further build on the uncompromising capabilities that have helped established PTG Holroyd rotor grinding machines as a favoured choice for many manufacturers of refrigeration compressors, helical rotors and threads.

“Although we are not able to name this North American customer, it is nonetheless rewarding to know that the positive experience gained by using one of our machines over so many years, played a significant part in their decision to order a second PTG Holroyd machine.”
