Custom CNC Machining (Milling & Turning)
SHENZHEN BENXIN ELECTRONIC HARDWARE CO., LTD
Product Details
Custom CNC machining is our core service. Using in-house CNC milling and turning lines, we produce precision metal parts from stainless steel, aluminum, brass, and carbon steel — from single prototypes to mass production. Whether you need a machined flange, manifold block, shaft, gear, or a complete custom component, we manufacture parts that meet your drawing, tolerance, and finish requirements.
Key Features
- CNC milling and turning for complex geometries
- Tight dimensional tolerances (typical ±0.01 mm, per drawing)
- Multi-material capability: stainless steel, aluminum, brass, carbon steel
- Secondary operations: drilling, tapping, threading, deburring
- Surface finishing: polishing, passivation, anodizing (per request)
- Prototype to volume production with consistent quality
- OEM/ODM — we work from your drawings and samples

Frequently Asked Questions
Yes. We provide OEM/ODM custom manufacturing from your drawings in PDF, DWG, STEP, IGES or STL formats.
- What materials can you machine?
Aluminum, stainless steel (304/316), titanium alloy, copper, brass, POM, PEEK and other engineering plastics. - What is your tolerance standard?
General tolerance ±0.05mm, tight tolerance down to ±0.005mm upon request. - Can you provide material certificates & inspection reports?
Yes, 3.1 material cert, FAI, CMM inspection report are available. - What is your lead time?
Sample: 3–7 working days. Mass production: 7–15 working days, depends on complexity & quantity. - Do you support small batch & prototype orders?
Yes, we welcome prototype, low-volume and custom one-off parts. - What surface finishes can you offer?
Anodizing, sandblasting, passivation, polishing, powder coating, laser marking, deburring. - How do you handle shipping?
We support DHL, FedEx, TNT, sea freight, and can do DDP / DAP terms.
- Is there a minimum order quantity (MOQ)?
We have no strict MOQ. We accept prototype trial orders as low as 1 piece. - How can I get an accurate quotation?
Please send us your 3D STEP/IGES file, 2D drawing with tolerance, material requirement, quantity and surface finish. - Can you help with DFM optimization?
Yes. Our engineers provide free DFM suggestions to reduce machining cost and improve manufacturability. - How long is the quotation valid?
Quotation is normally valid for 30 days, subject to raw material price fluctuation.
Pricing depends on material, dimensions, tolerance, quantity and surface finish. Please send your drawings (PDF/DWG/STEP/IGES) and we will provide an exact quote, usually within 24 hours.
The price is based on material cost + machining time + surface treatment + tooling (if any) + packaging and freight.
Our standard quotes are FOB Shenzhen/Dongguan unless otherwise stated. Air or sea freight can be quoted separately according to your destination.
Our price reflects the material grade, tolerance level, full inspection and finishing quality. If needed, we can suggest cost-saving design changes (e.g. relaxing non-critical tolerances) to reduce the cost.
Yes. We provide tiered pricing — the unit price decreases as the quantity increases. Please tell us your target quantity for the best price.
