VT machining specialises in CNC Punching 3004 Aluminum. Because 3004 Aluminum is lightweight with excellent machinability, and its machinability is excellent; high cutting speeds and superb finishes achievable, we plan each job around the grade to protect accuracy and surface quality.
CNC Punching Capability for 3004 Aluminum
- Lightweight (~2.7 g/cm³)
- Excellent machinability
- Tolerance to ±0.01 mm
- Anodising-ready
Machining 3004 Aluminum with CNC Punching
3004 Aluminum behaves predictably under CNC Punching once parameters are dialled in: machinability is excellent; high cutting speeds and superb finishes achievable, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 3004 Aluminum run consistently from one batch to the next.
CNC Punching Tolerances & Surface Finish
Punched 3004 Aluminum holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
CNC Punching Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every 3004 Aluminum part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished 3004 Aluminum parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Design Tips for CNC Punching 3004 Aluminum
We are happy to suggest design tweaks that improve manufacturability. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched 3004 Aluminum. If you send your model early, we will return practical DFM feedback before you commit to production.
Why 3004 Aluminum?
3004 Aluminum is chosen when a part needs what this grade offers — it is lightweight with excellent machinability. We confirm the grade and any temper or heat-treat condition with you before machining.
