In the field of modern mechanical manufacturing, Custom CNC Milling has become the preferred method for producing complex components due to its outstanding precision and flexibility. As a professional provider of precision machining services, Mocayo is here to offer a comprehensive overview of the core advantages of CNC milling technology.  From prototypes to volume production, we provide custom CNC milling for complex milling parts. Experience consistent quality, expert support, and competitive pricing.

Unlike turning, where the workpiece rotates against a stationary tool, CNC milling utilizes rotating cutting tools to machine a stationary workpiece. This makes Custom CNC Milling ideal for fabricating flat surfaces, grooves, gears, and other intricate geometries. Mocayo’s milling centers feature both 3-axis and 5-axis configurations:

• 3-axis machines are highly efficient and economical for 90% of standard milling parts;

• 5-axis simultaneous systems enable high-precision milling of complex curved surfaces in a single setup, reducing fixturing steps and enhancing accuracy.

Typical milling parts manufactured by Mocayo include:

• Flat parts, such as mounting plates and flanges, with flatness up to 0.02mm/300mm

• Curved surface parts, including mold cavities and impellers, with ±0.05mm surface accuracy

• Box-type components, such as valve bodies and gearbox housings, with hole positioning tolerance within 0.03mm

Key Technical Indicators of Precision Milling
In the world of precision component manufacturing, quality control is a core competency. Mocayo has established a complete dimensional accuracy management system to ensure that every milling part meets strict quality standards.

Our tolerance capabilities include:

• Standard machining: IT8 grade (±0.05mm)

• Precision machining: IT7 grade (±0.025mm)

• High-precision machining: IT6 grade (±0.01mm)
  For special surfaces, we optimize cutting parameters and tool paths to control tool marks and meet assembly interface requirements.

All Custom CNC Milling processes at Mocayo follow strict process documentation and undergo 100% inspection at key stages, ensuring consistent and reliable part quality.

Milling Part Selection Guidelines
Proper material and process design are key to achieving optimal results. Mocayo’s experienced engineers offer the following recommendations:

Material–Process Matching

• Aluminum alloys: Cutting speed 200–400 m/min, feed per tooth 0.1–0.2 mm

• Stainless steel: Cutting speed 80–120 m/min with specialized tools

• Engineering plastics: Cutting speed 300–500 m/min, with attention to heat control

Quality Inspection Standards

• First Article Inspection: full dimensional checks to confirm process reliability

• Batch Sampling: follows GB/T 2828 standards

Each inspection report includes:

• Critical dimension measurements

• Surface roughness readings

• Material hardness results

• Geometric tolerance validations

We strongly recommend that clients provide detailed technical requirements at the early project stage. Mocayo can offer process optimization suggestions to reduce costs and enhance efficiency throughout your Custom CNC Milling project.
