Taiwan firm chooses UK rotor-milling machineWhen one of Taiwan’s leading air and refrigeration compressor specialists needed to improve its rotor-milling capability, it selected a 3EX-R rotor production centre from UK-based Holroyd Precision Ltd, Rochdale (www.ptgltd.com), having previously bought several rotor-milling and rotor-grinding machines from the company.

Installed in August, the 3EX-R gives Holroyd’s customer the level of performance and reliability it needed for rough milling rotor blanks up to 350mm in diameter.

PTG Group business development director Neil Jones said: “We were incredibly pleased to secure repeat business from such long-standing and valued customers.

“Over recent years, we have supplied them with three rotor-milling machines, a TG350 grinding machine and a tool management centre. Being more than familiar with the uncompromising standards offered by our machinery, they did not wish to take a chance on performance, repeatability and productivity by selecting an alternative solution.”

The performance of the EX-series machines is attributed to the advanced technology they incorporate, which includes on-machine probing and the use of dry-milling techniques.

The machines cut a full-depth groove by traversing the cutting tool through the material at the appropriate helix angle, while at the same time rotating the component in the C axis. Digital drive technology controls all axis movements.
