CNC Machining (Computer Numerical Control Machining)
CNC machining is a digital manufacturing process that uses pre-programmed software (CAD/CAM) to control precision machine tools, cutting and shaping materials such as metals, plastics, and composites.
Core Process
The core process includes: 3D modeling → toolpath planning → tool selection (milling cutters, turning tools, drills, etc.) → multi-axis cutting → surface finishing (polishing/anodizing).
Core Advantages
- Ultra-High Precision
- Tolerances can reach ±0.001 inches (0.025mm), with a surface roughness of Ra 0.8-3.2μm, meeting the stringent requirements of aerospace precision parts (e.g., turbine blade fixtures) and medical implants (e.g., titanium alloy joints).
- Complex Geometry Adaptability
- Supports five-axis machining for deep cavities, curved surfaces, and micro-holes (minimum diameter 0.1mm), achieving integrated forming and reducing assembly processes.
- Flexibility and Efficiency
- No mold investment is required, enabling rapid response from prototyping to small-batch production (1-1000 pieces), with lead times as short as 1 day.
- Universal Material Compatibility
- Covers aluminum alloys, titanium alloys, stainless steel, engineering plastics (e.g., PEEK), and composites, with hardness processing ranges of HRC 20-65.
- Automation and Consistency
- 24-hour continuous machining with repeat positioning accuracy of ±0.005mm, achieving a product yield rate of >99% and significantly reducing human error.
Typical Applications
Typical applications include precision molds, automotive engine blocks/transmission components, drone structural parts, and electronic heat sinks.
CNC Machining vs. Casting
Compared to casting, CNC machining, with its “mold-free, fast response, and complex solutions” technical characteristics, has become the core method for manufacturing high-value, customized metal/non-metal parts, especially in new product development and high-precision repair fields.
Industry Positioning
CNC machining, with its “mold-free, limitless precision” capabilities, has become the preferred process for high-value metal parts in aerospace, medical, automotive, electronics, and defense industries. It is particularly suitable for scenarios involving complex structures, small-batch customization, and hard-to-machine materials (e.g., titanium alloys, high-temperature superalloys), making it indispensable in rapid prototyping and precision manufacturing.

Design Guidelines for CNC Machining
| Description | |
|---|---|
| Radii | In CNC machining, sharp internal corners on a workpiece will naturally form rounded corners (radii). The depth must not exceed 12 times the diameter of the drill. For end mills, the depth must not exceed 10 times the diameter of the tool. |
| Threads and Tapped Holes | Diameter Φ 1.5-5 mm, depth: 3 times the diameter. Diameter Φ 5 mm or larger, depth: 4-6 times the diameter. RapidDirect can produce threads of any specification and size as required by the customer. |
| Undercuts | Square profiles, full radius, dovetail profiles. |
| Text | CNC Milling: Minimum width of 0.5 mm and depth of 0.1 mm. CNC Turning: RapidDirect can use laser marking to create standard text for CNC turned parts. RapidDirect can create standard text via CNC engraving or laser engraving as per customer requirements. |
