A previously owned piece of machinery from PTG Holroyd will be fully refurbished and upgraded before being shipped to a German compression equipment specialist.

The PTG Holroyd 2E-volution CNC rotor milling machine will undergo a full refurbishment and upgrade programme, during which it will be transformed into a state-of-the-art ‘new’ PTG Holroyd 2E-volution rotor production centre.

Manufactured in 1993, the PTG Holroyd 2E-volution rotor miller is currently at PTG Holroyd’s machine tool technology centre where, after a complete overhaul and full mechanical refit using genuine Holroyd components, it will also benefit from the integration of Siemens’ future-proof SINUMERIK ONE CNC control.

Rebadged as a PTG Holroyd 2E-volution rotor production centre, it will provide rapid setup, intuitive user-friendly operation and the latest levels of accuracy, reliability and productivity.

PTG Holroyd sales director, Mark Curran 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’ incredible ‘Run MyVirtual Machine’ capability, meaning they will be able to mill virtual rotors on the desktop before commencing physical production. 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.”
