Precision Multi-axis Machining for Complex Components

Custom CNC Milling Parts is our core customized processing service for global industrial purchasers. Our factory is equipped with 3/4/5-axis vertical CNC milling centers, high-speed machining centers and gantry milling equipment to produce custom metal & plastic milled components with strict dimensional tolerance and fine surface finish. Certified by ISO9001:2015, we support rapid prototype machining, small batch customization and large-volume mass manufacturing for customers’ OEM & ODM projects.

Different from conventional cutting, multi-axis CNC milling realizes complex 3D contour, cavity and irregular profile machining directly from clients’ CAD, STEP, IGS, DWG drawings or physical samples. We supply full one-stop solution including free DFM analysis, raw material selection, precision CNC milling, customized surface finishing and complete QC testing for all custom milled spare parts.

Core CNC Milling Processing Capability

• 3/4/5 Axis Milling: Max blank size 1200×800×500mm, standard tolerance ±0.02mm, ultra-precision down to ±0.005mm

• High-Speed Slot & Hole Machining: Min drill hole 0.1mm, deep cavity milling available

• Contour 3D Machining: Complex curved surface & multi-angle undercut processing without dead zone

Core Advantages of Custom CNC Milling Parts

• High Precision Control: Standard tolerance ±0.02mm, critical precision parts reach ±0.005mm, compliant with aerospace, medical and automotive industrial precision standards.

• Complex 3D Structure Machining: Multi-axis milling enables deep cavity, thin-wall, irregular curved and multi-angle parts that ordinary processing cannot finish.

• Rich Material Compatibility: Process all common metal and engineering plastic; each batch raw material provides official MTR material certification to guarantee stable mechanical performance.

• Stable Batch Consistency: Automated CNC programming reduces manual error, above 99.9% dimensional consistency during mass production.

• Full-Spectrum Custom Service: Free DFM optimization, prototype verification, batch production, post surface treatment and full inspection to shorten your procurement cycle.

• Zero MOQ & Fast Leadtime: No minimum order limit, accept 1pc prototype to bulk production over 100,000pcs; urgent prototype available within 24~48h.

Standard CNC Milling Production Flow

Our standardized production flow strictly controls each working procedure to avoid deformation and dimensional deviation for milled parts, detailed steps as below:

1. Drawing & DFM Check: Engineers verify dimension, tolerance and structural feasibility, provide free design optimization advice.

2. Raw Material Prep: Select qualified certified material, cut into standard blanks as per part dimension.

3. CAM Programming & Simulation: Generate G-code from 3D model, simulate cutting to prevent tool collision.

4. Rough Milling: Remove surplus material with large cutting allowance to shape basic outline of workpiece.

5. Finish Precision Milling: Fine cut to reach final dimension tolerance and required surface roughness.

6. Deburring: Remove sharp edges and tiny burrs for subsequent surface treatment.

7. Complete Quality Inspection: Test dimension via CMM and roughness tester, issue official inspection documents.

8. Anti-shock Packaging & Global Delivery: Custom export package, support air, sea and express worldwide shipping.
