Our CNC Services
CNC Turning
CNC turning delivers high-precision rotary parts with excellent concentricity and surface finish. Our turning-milling composite technology cuts errors and lead times, supporting all volumes from prototyping to mass production.
CNC Milling
CNC milling is our core precision service for complex custom parts. With 3/4/5-axis machines, we deliver high-accuracy, repeatable parts for prototyping and mass production, across mechanical, aerospace, medical, and electronic applications.
CNC Machining for Prototyping
Fast CNC prototyping with reliable material and high precision. We supply prototypes within 1–3 days and offer DFM support, accelerating your product development and launch.
Surface Finishing
Surface finishing services improve product aesthetics, durability and performance. We offer polishing, anodizing, plating, powder coating and more, protecting parts from wear and corrosion.
CNC Machining Materials
We have rich processing experience in various industrial-grade metal and plastic materials, meeting the functional requirements of different industries such as high strength, corrosion resistance, high temperature resistance, and insulation. All raw materials are sourced from qualified suppliers with complete material certificates to ensure product stability and reliability.
Metal Materials
Aluminum alloy (6061, 7075, 5052), stainless steel (303, 304, 316, 316L), carbon steel, alloy steel, brass, copper, titanium alloy, magnesium alloy, etc. These metal materials are widely used in high-strength, wear-resistant, and corrosion-resistant industrial scenarios.
Plastic Materials
PEEK, POM, PA66, ABS, PC, PMMA, PET, PTFE, UHMWPE and other engineering plastics. Plastic machining parts are commonly used for insulation, anti-corrosion, lightweight, and non-metallic structural applications.
Tolerances for CNC Machining
Precision tolerance control is the core advantage of our CNC machining service. We implement strict dimensional inspection standards in the whole production process to ensure the consistency and interchangeability of batch parts.
We adopt professional testing equipment including CMM, micrometer, height gauge, and roughness tester for full inspection of key dimensions, providing inspection reports to support customer quality verification.
| Project | Specification |
| Standard Tolerance | ±0.02mm – ±0.05mm (for conventional machining parts) |
| High Precision Tolerance | ±0.005mm – ±0.01mm (for precision components) |
| Ultra-Precision Tolerance | Minimum tolerance up to ±0.001mm (for special industrial parts) |
| Surface Roughness | Ra 0.8μm – Ra 3.2μm (adjustable according to customer requirements) |
