CNC Machining Services Sydney — 3-Axis & 5-Axis Precision Engineering
From prototype to production, our CNC machining services deliver precision-engineered components with tolerances as tight as ±0.01mm. We operate both 3-axis and 5-axis CNC centres from our Wetherill Park facility in Sydney, providing engineering-led manufacturing for complex aerospace, defense, medical, automotive, and energy components.
CNC Machining Explained
CNC machining is a subtractive manufacturing process where computer-controlled cutting tools remove material from a solid workpiece to create precision components. At CNC Industries in Western Sydney, we use advanced multi-axis CNC machining centres to produce parts ranging from simple brackets to complex aerospace geometries with tight tolerances and superior surface finishes.
Our engineering-led approach means every CNC machining project starts with a Design for Manufacturability review. We assess your part geometry, material selection, and tolerance requirements to recommend the most efficient machining strategy — whether that is 3-axis milling for straightforward prismatic parts or 5-axis simultaneous machining for complex multi-face components.
Capabilities
3-Axis CNC Milling
Ideal for prismatic parts, flat surfaces, and high-volume production runs. Our 3-axis centres handle envelopes up to 1200×600×600mm with ±0.01mm positional accuracy.
5-Axis CNC Machining
For complex geometries requiring multi-face access in a single setup. Simultaneous 5-axis interpolation on Ø500mm trunnion tables eliminates repositioning errors and achieves tighter tolerances on compound-angle features.
CNC Turning
Precision turning for cylindrical components up to Ø300mm with live tooling for cross-drilling and milling operations in a single setup.
Real-World Applications
Aerospace structural brackets, hydraulic manifold blocks, medical device housings, automotive engine components, defense weapon system parts, data centre mounting hardware, energy sector valve bodies, and precision jigs and fixtures.

Frequently Asked Questions
How much does CNC machining cost in Sydney?
CNC machining costs depend on material, complexity, tolerances, and quantity. Simple aluminium parts may start from $50-100 per unit, while complex 5-axis aerospace components can be $500+ per unit. We provide detailed quotes within 48 hours.
What tolerances can CNC machining achieve?
Standard tolerance is ±0.05mm, with precision tolerances of ±0.01mm achievable for critical features. Surface finishes from Ra 3.2µm to Ra 0.8µm are available.
What file formats do you accept for CNC machining?
We accept STEP, IGES, Parasolid, SolidWorks, and Inventor native files. 2D drawings in PDF or DXF format are also accepted for quoting.
