Post-Processing
Deburring, heat treatment, cleaning and pre-finish preparation — the stretch between machining and finishing where parts most often go wrong.
A part is not finished when it comes off the machine. Burrs left behind cut the hands of whoever assembles it and spoil sealing; residual stress shows up as distortion in later operations; inadequate cleaning turns into blotchy anodising. None of these steps is complex on its own, but spread across several shops, the extra handling makes damage and delay routine.
We schedule this stretch in house: parts go from machining straight into post-processing without leaving the building. One planner owns the order of operations, so when something goes wrong there is no argument between suppliers.
Capabilities
- Deburring
- Hand finishing, filing, abrasive belt, vibratory tumbling — selected by precision and batch size
- Heat treatment
- Stress relief and ageing arranged per material requirement (subcontracted; supplier list to be confirmed)
- Cleaning
- Ultrasonic cleaning and drying as standard preparation before finishing
- Batch range
- In step with machining, from one piece
Solutions
Deburring precision parts
Cross holes and thin-wall edges that standard tooling cannot reach are handled by hand with dedicated tools, without touching mating faces.
Stress relief between operations
Scheduled after roughing to reduce distortion after finishing — particularly for thin walls and high length-to-diameter parts.
Preparation before finishing
Cleaning and pre-treatment matched to the downstream process (anodising / blasting / painting) to reduce colour variation and adhesion failures.
Process Overview
The value of post-processing is not in how advanced any single step is, but in whether the order is right. Stress relief after finish machining achieves nothing; no anodising line can rescue a part that was not properly cleaned. Our rule: anything that induces distortion goes before finish machining, and anything affecting appearance runs straight into finishing without sitting overnight.
Design Guide (DFM)
Say which edges need deburring
"Deburr all over" cannot be inspected against. Call out the edges that affect assembly and safety.
Allow stress relief on thin-wall parts
For walls under about 1.5mm or high length-to-diameter parts, state the requirement on the drawing.
Mark cosmetic faces on the drawing
Which face is cosmetic determines work holding and processing order. Unmarked, it is guesswork.
Quality Control
- Visual and tactile check after deburring; critical holes checked with go/no-go gauges
- Furnace records retained for heat-treated parts (obtained from the supplier for subcontracted work)
- Holding time between cleaning and finishing controlled to avoid re-oxidation
- Cosmetic faces separated during transfer to reduce handling damage
FAQ
Can post-processing be ordered on its own?
Yes. Supply the parts and a clear specification. We inspect incoming condition first, so we are not endorsing the previous operation.
Is heat treatment done in house?
It is subcontracted to suppliers with the relevant capability. We handle scheduling, transport and record collection. The supplier list depends on the actual arrangement (to be confirmed).
How thorough is deburring?
Standard requirement is no snag by hand and no effect on assembly. If you have a specified burr height limit, mark it on the drawing and we will inspect to it.
