CNC Machining Service for Aluminium Copper and Stainless Parts
This CNC service covers machined metal parts in aluminium alloy, copper, stainless steel and zinc alloy, held to ±0.1mm/100mm machining accuracy with a maximum molding size of 3000*1200*850mm.
Product Overview
This CNC service covers machined metal parts in aluminium alloy, copper, stainless steel and zinc alloy, held to ±0.1mm/100mm machining accuracy with a maximum molding size of 3000*1200*850mm. It supports drawing customization, sample customization, proofing and mass production for buyers who need machined parts rather than a finished input device. KEYU runs the equipment in house at its Shenzhen factory alongside sheet metal and stamping lines.
- ±0.1mm/100mm machining accuracy suits structural parts that must mate with existing assemblies
- A 3000*1200*850mm maximum molding size covers large chassis and frame work in one setup family
- Four material families in one supplier removes the need to split an assembly across vendors
- Lead time of 3-7 days on sheet metal work keeps development iterations short
- ISO9001:2015 quality management system governs the processing workflow
Application Scenarios
- Medical equipment housings and mounting brackets
- Financial instrument internal structures
- 5G communication chassis parts
- Automated robot frames and machined fittings
- Car audio and navigation mounting hardware
- Shield covers and shrapnel parts
Who It Is For
- Product engineers sourcing machined prototypes and production parts
- Equipment OEMs consolidating machining and sheet metal with one factory
- Buyers supplying their own material for incoming material processing
Problems It Solves
- Prototype shops cannot follow through into mass production at the same tolerance
- Split sourcing between machining and sheet metal creates fit problems at assembly
- Large frame parts exceed the envelope of small machining centres
- Drawings need proofing before tooling commitment
Technical Features
- CNC machining accuracy of ±0.1mm/100mm
- Maximum molding size of 3000*1200*850mm
- Laser cutting accuracy of ±0.05mm/100mm on companion sheet parts
- Stamping forming accuracy of ±0.2mm/100mm
- Carbon steel plate up to 10mm and stainless steel plate up to 6mm on the cutting line
- Fiber laser cutting, CNC bending, riveting, welding and hydraulic pressing in house
- ISO9001:2015 quality management system

How It Compares
| Prototype only machine shop | The same line runs proofing and mass production so tolerances do not shift between stages |
|---|---|
| Sheet metal only supplier | CNC at ±0.1mm/100mm sits alongside laser cutting at ±0.05mm/100mm in one factory |
| Small envelope machining centres | Maximum molding size reaches 3000*1200*850mm for large frames |
Use Guide
- Send 2D or 3D drawings with tolerances and material grade stated
- Confirm whether the part stays inside the 3000*1200*850mm envelope
- Request a proofing sample before committing to mass production
- Specify post machining surface treatment requirements with the drawing
- Tell us if you will supply material so incoming material processing can be quoted
