Our Custom CNC Milling Services

Customizing the right 3-axis, 4-axis, or 5-axis CNC milling service is crucial for maximizing your return on investment.

3-axis CNC center at Rapid Model's factory

3-Axis CNC Milling Services

With our 3-axis milling machines and experienced engineering team, we can consistently maintain tolerances within ±0.01mm, and in special cases, our engineers have even achieved ±0.005mm.

4-axis CNC center at Rapid Model's factory

4-Axis CNC Milling Services

When your CNC components require machining of complex angled surfaces, helical grooves, and curved contours, choosing custom 4-axis CNC milling services can be a more cost-effective and efficient alternative to using a 5-axis milling machine.

Six Types of CNC Milling Selection

We offer comprehensive CNC machining solutions tailored to your specific requirements

Precision Milling

High-accuracy CNC milling services with tolerances down to ±0.0005" for complex geometries and tight specifications.

Rapid Prototyping

Fast-turn CNC prototyping services to accelerate your product development cycle and reduce time-to-market.

CNC 3-Axis Milling

For standard CNC metal parts or other milling components that don't require complex machining, 3-axis CNC milling is the most cost-effective choice.

3D & 5-Axis Milling

Advanced multi-axis machining for complex parts with intricate geometries and challenging features.

Secondary Operations

Comprehensive finishing services including deburring, polishing, anodizing, plating, and painting.

CNC 4-Axis Milling

Built on the foundation of 3-axis milling, 4-axis milling adds an additional rotational axis, making it an ideal intermediate option between 3-axis and 5-axis milling.

Precision CNC Milling for Metal Parts

Advanced technology and expertise to handle your most challenging projects

Advanced equipment

Our precision CNC milling services are ideal for manufacturing metal parts such as aluminum, steel, and titanium. These materials are widely used in industries with high strength and durability requirements, such as aerospace and automotive. We have a 20% speed advantage in prototyping and small-batch production compared to industry standards, and in large-scale manufacturing, we consistently maintain positioning repeatability between ±0.002 and ±0.005mm.

  • 20+ CNC milling machines with 3, 4, and 5-axis capabilities
  • Maximum part dimensions: 24" x 16" x 12"
  • High-speed machining for aluminum, steel, and titanium
  • Live tooling for complex geometries

Our experienced team of machinists and engineers ensures that every project is executed with precision and efficiency, meeting the client's quality standards.
