Full OEM rebuild to transform 1990s Holroyd rotor miller

Full OEM rebuild to transform 1990s Holroyd rotor millerFor a Germany manufacturer of specialist compression equipment, the opportunity to purchase a previously-owned PTG Holroyd 2E-volution CNC rotor-milling machine from the Rochdale-based manufacturer was an opportunity not to be missed because, before being shipped to Germany, the machine will undergo a full refurbishment and upgrade programme.

Manufactured in 1993, the PTG Holroyd 2E-volution rotor miller (for manufacturing helical rotors with a maximum diameter of 200mm) is currently at PTG Holroyd where, after a complete overhaul and full mechanical refit using genuine Holroyd components, it will also benefit from the integration of a Siemens’ future-proof Sinumerik One CNC system. Rebadged as a PTG Holroyd 2E-volution rotor production centre, it will provide rapid set-up capabilities, intuitive user-friendly operation, and the latest levels of ‘accuracy, reliability, and productivity’.

Mark Curran, PTG Holroyd’s sales director, said: “The sheer number of older PTG Holroyd 2E-volution machines still in daily use around the globe says a great deal about their quality and longevity, as well as the faith our customers place in them. In fact, many of our customers have requested a full retrofit and upgrade to bring performance up to current day standards.

“The Sinumerik One upgrade alone will provide our German customer with Siemens’ ‘Run MyVirtual Machine’ capability, meaning they will be able to mill virtual rotors on the desktop before commencing physical production — and the risk of legacy software issues going forward will also be reduced. PTG Holroyd machines are built to last, and an E-volution upgrade, which is suitable for many of our older CNC milling machines, enables customers to update their machine tools and gain the accuracy and performance of a current model at much lower cost than purchasing new.”
