What tolerances can you hold on CNC machined parts?
We routinely hold tolerances as tight as 0.01 mm on critical features, with surface finishes to suit aerospace, medical and defence applications.
Sydney CNC Machine Shop
Precision CNC Machining in Sydney
McIver Engineering is a full-service CNC machine shop in Sydney delivering CNC milling, CNC turning and multi-axis machining for prototype and production runs across NSW and Australia since 1947. Our workshop is on Woodpark Road in Smithfield, so Western Sydney manufacturers can drop off drawings and collect parts.
What we machine
CNC milling on 3 and 4 axis platforms
CNC turning for shafts, bushes and complex round parts
Tolerances within 0.01 mm on critical features
Aluminium, steel, stainless, brass, titanium and engineering plastics
Prototype, low volume and ongoing production batches
Parts machined in our Sydney workshop with material certificates supplied on request
Why specify McIver Engineering for CNC machining
Our Smithfield workshop combines modern CNC platforms with machinists who have decades of precision experience. A design for manufacture review is available before a tool ever moves so you get parts that fit first time.
We work directly from STEP, IGES, DXF, DWG and PDF drawings, and provide design feedback where it saves you money. From a single prototype to ongoing supply, every part is inspected before it leaves our Sydney workshop.
McIver Engineering is part of the Perfetti Engineering Pty Ltd group, alongside Global Supply Network, which gives clients a single Sydney point of contact for local precision machining and global sourcing.

CNC milling
CNC milling suits parts with prismatic geometry, pockets, faces, holes and contoured surfaces. Brackets, manifolds, housings, jigs, fixtures and tooling plates are all natural fits.
Multi-axis milling lets us produce features in a single setup that would otherwise need several operations. That means tighter cumulative tolerances and faster turnaround.
Send us your STEP and DXF files and a design for manufacture review by our Sydney engineers is available before machining begins.
- 3 and 4 axis vertical machining centres
- Complex pockets, contours and slotted features
- Steel, stainless, aluminium, brass, titanium and engineering plastics
- Tight positional tolerances on multi-feature parts
- Prototype through to ongoing production batches
- In-house inspection and full traceability
CNC turning
CNC turning is the most efficient route for cylindrical and round components. Where parts also need flats, cross holes or off-axis features, live tooling on our lathes lets us combine operations in one setup.
We work directly from STEP, IGES and 2D drawings and quote prototype, batch or ongoing supply on the same enquiry.
- CNC lathes with live tooling for combined turn and mill operations
- Bar-fed work for small to mid diameter parts
- Threads, knurls, bores, grooves and complex profiles
- Steel, stainless, aluminium, brass and bronze
- Prototype through to ongoing production batches
- Inspected to drawing before despatch

For repeat production quantities that do not need to be machined in Sydney, our sister business Global Supply Network sources CNC machined parts overseas with engineering oversight from the same group.
Frequently asked questions
Do you have a minimum order quantity?
No. We machine one-off prototypes and ongoing production batches from the same workshop, and quote each project on its merits.
What CAD file formats do you accept?
STEP, IGES, DXF, DWG and PDF drawings. If you only have a sample part we can reverse engineer it in our Sydney workshop.
How many axes do you mill on?
We mill on 3 and 4 axis CNC vertical machining centres, choosing the right platform for each part.
What materials do you mill?
Steel, stainless, aluminium, brass, titanium and engineering plastics including Delrin, nylon and PEEK.
What size of turned parts can you produce?
Most production work falls in the small to mid diameter range, with longer parts handled on dedicated platforms. Send your drawing and we will confirm the right machine for the job.
Can you combine turning and milling in one setup?
Yes. Our CNC lathes have live tooling, which means cross holes, flats and slots can be added during the turning cycle.
