Enex Engineering is a Perth-based CNC machining workshop. We make precision parts for WA mining, oil & gas, rail, valve OEMs and heavy-haulage operators — and we run an aftermarket catalogue of 79 trailer SKUs alongside it.
Every machine shop says they care about quality. The question is whether the people who promise the part on Monday are the same people pushing the buttons on Wednesday. At Enex, they are.
Drawings come in and go straight to an engineer with hours on the same lathes and mills that will cut the part. There's no quoting team retranslating to the shop, no broker re-brokering to a workshop in Adelaide, no portal that auto-prices things the workshop can't actually run. If the geometry is awkward, we'll say so on day one. If a different process or material would deliver the same function for a fraction of the cost, we'll suggest it before you commit.
The result is fewer surprises. Quotes that hold. Lead times that get hit. And — most of the time — first-article parts that pass inspection and go straight into service.
From two-person turning shop to an eight-strong machine shop with one of Australia's most capable Wire EDM cells.
Enex opened in Malaga with CNC turning, milling and Wire EDM on the floor from the start. Built around precision work for WA mining, oil & gas, valve and trailer customers.
First long-form production contract — wear pins for a tier-2 trailer OEM. Six-month rolling order, machined, heat-treated and dispatched out of Malaga every fortnight. The discipline of running parts in volume reshaped how we set up jobs.
Added two more CNC lathes and a four-axis machining centre. Capacity to take on larger production runs and mill prismatic parts in a single setup.
Launched an aftermarket programme — 79 SKUs covering pins, bushings and wear parts for the most common heavy-haulage trailer brands. Enquire for current availability and lead time.
Added a Seibu wire-cut EDM — the first of its kind installed in Australia. Sub-0.005mm tolerance in hardened steel, opening up tooling, die and valve-internals work that conventional machining can't reach.
Formalised reverse-engineering as a standalone service. Worn part in, drawings and direct-fit replacement out — typical turnaround 5-10 working days. Especially valuable for obsolete parts where the OEM has moved on.
A team of eight — seven engineers and machinists, plus an office manager keeping quotes, jobs and freight moving. Eight CNC machines across milling, turning and Wire EDM — including Australia's first Seibu wire-cut EDM — plus manual lathe, surface grinder and laser engraver. Quotes returned in 24-48h. Servicing customers from Geraldton to Darwin to Adelaide, with weekly direct freight to every WA mining hub.
Six process types under one roof — turning, milling, wire EDM, manual lathe, surface grinding and laser engraving. The honest spec, line by line.
| CNC Milling | 3 machining centres — travel envelope X 1,280 × Y 600 × Z 600 mm. Big enough to take housings, manifolds and prismatic mining parts in a single setup. |
|---|---|
| CNC Turning | 3 lathes — max turning Ø 450 mm. Shafts, bushings, flanges, pins and rotational components in 4140, stainless, bronze and aluminium. |
| Wire EDM | 2 machines — a Seibu (Seibu invented the wire-cut EDM; ours is the first Seibu wire-cut machine in Australia) and a Sodick with 300 mm Z-height for tall hardened-steel work. Sub-0.005 mm tolerance, burr-free. |
| Manual lathe | 1 conventional lathe for one-off proto, rework and on-the-fly repair jobs that don't warrant a CNC setup. |
| Surface grinder | 1 surface grinder for ground finishes on hardened plates and parallels — flat to a couple of microns, mirror-grade Ra where the drawing calls for it. |
| Laser engraver | 1 laser engraver for permanent part marking — serials, lot codes, heat numbers, logos. In-house traceability without sending parts out. |
| Hours | Mon-Fri, 7:00am to 5:00pm AWST. After-hours machining for production runs by arrangement. |
The Malaga industrial area sits 14km north-east of Perth CBD, on the doorstep of the Great Northern Highway and Tonkin Highway feeding the Pilbara, Mid-West and Goldfields freight networks.
In practice that means a part finished at 3pm Friday is in Karratha by Tuesday morning, Port Hedland by Wednesday, Kalgoorlie by Monday next, and Geraldton overnight. We have weekly direct services to every major WA mining hub plus regular runs to Adelaide and Darwin.
Three people answer the day-to-day calls and emails. Directors are hands-on; the manager runs the floor and quoting cycle. Reach out to any of us directly.
