CNC machining capabilities
Machining, materials and inspection — what we can hold and how each batch is checked.
Processes
Four processes cover most custom parts
CNC milling
Brackets, housings and plates with pockets, slots and mounting holes.
CNC turning
Sleeves, bushings, spacers and shafts with controlled bore and wall.
Drilling & tapping
Bolt patterns, threaded holes and cross holes on machined parts.
Surface finishing
Anodising, passivation, black oxide and zinc plating through partners.
Materials
Common metals we machine
- Aluminium 6061 / 7075
- Lightweight parts, frames and housings.
- Stainless 304 / 316
- Corrosion-resistant parts for food and medical equipment.
- Carbon steel
- Structural parts, flanges and wear components.
- Brass & bronze
- Bushings, fittings and electrical parts.
Tolerance & inspection
Checked against your drawing
Tolerance is confirmed per part during drawing review — we do not quote a blanket tolerance. Every batch follows the same checks.
- 01
Drawing review
Critical dimensions and datums agreed before machining.
- 02
In-process checks
Key dimensions measured during the run, not only at the end.
- 03
Final inspection
Last check against the drawing before packing and shipping.
How an order runs
Four steps from drawing to delivery
- 01
Send the drawing
PDF, STEP or DWG with material and quantity.
- 02
Quote & confirm
Price, process and finishing confirmed in writing.
- 03
Machine & inspect
Sample checked first, then the batch runs.
- 04
Pack & ship
Protective packing and shipping to your address.
FAQ
Questions buyers ask first
What file formats can you quote from?
PDF drawings, STEP and DWG files are all workable. Please include material, quantity and any critical tolerance.
Can you start with a small sample batch?
Yes. Sample runs are quoted separately so you can check the part before a larger batch.
How is tolerance decided?
Tolerance is reviewed against your drawing. If a dimension cannot be held as drawn, we raise it before production.
How do we communicate during the order?
By email or WhatsApp in English, Chinese or Russian, with photos of the parts when useful.
