EX Series SETTING THE STANDARD IN CNC PROfILE MILLING Holroyd EX Series CNC rotor milling machines have earned global acclaim for their high speed, high precision and unrivalled build quality. Delivering class-leading performance and reliability, ‘standard’ EX models can cut rotor or worm profiles in blanks of up to 850mm in diameter. Where 850mm is too small, we also offer a bespoke machine that can perform the same functions on blanks exceeding one metre in diameter. Whichever EX Series machine you invest in, you will find it provides exacting levels of performance and repeatability. This is due in no small part to advanced technology – such as our on-machine probing and dry milling techniques for some materials. The flexibility of EX Series rotor milling machines means they are equally efficient at producing complex components with helical screw profiles, as they are at milling gear parts such as worm shafts. See the EX Series in action at PTG Holroyd on YouTube. www.holroyd.com PTG The first name in precision Holroyd Precision is a member of the Precision Technologies Group (PTG) – an organisation that has established itself at the forefront of high-precision machine tool design, build and supply. The PTG range includes ultra-precision grinding machines for rotor, thread and gear operations; rotor milling machines; heavy duty lathes; deep hole boring machines; friction stir welding machines and special purpose machine tools for the manufacture of precision components.
