Precision Machining

Having the right equipment and knowing how to use it is critical for successful precision machining. Precision machining comes in all shapes and forms, and at Arex we have an extensive range of computerised numerical controlled (CNC) bending, turning, and milling machines to meet your unique component manufacturing requirements.

Arex’s workshop includes a state-of-the-art coordinate measuring machine (CMM), ideally suited for producing ‘perfect first articles’. From our rail industry experience, we understand the critical importance of producing a perfect first article, particularly to check compliance before embarking on a full-scale production program. Only after the physical dimensions of a component are defined precisely can the machining process begin, and this is our expertise.

Arex’s machining advantage

Machined parts are often incorporated into fabrications – which is where Arex excels, as we have an in-house machining and fabrication service. Many other manufacturers don’t offer our dual capability and they must subcontract their machining work, which increases costs.

Arex also provides a stress relieving capability for fabrications which have been machined after production. Stress relieving is a critical and integral element of the fabrication process. Stress relieving welded components ensures they are machined to the highest precision standards.
