Ⅰ：What is a CNC Machined Part?
CNC machined parts are precision components produced by computer-controlled tools that remove material from a solid block (called a blank or workpiece) to create a desired shape. The CNC process uses pre-programmed software to automate milling, turning, drilling, and other machining operations with extreme accuracy and repeatability.
CNC machining is widely used to produce both simple and highly complex parts with tight tolerances. It supports a broad range of metals and plastics and is ideal for rapid prototyping, low-to-medium volume production, and functional end-use parts in industries requiring reliability and precision.
Key Characteristics of CNC Machined Parts
• Exceptional Precision
Modern CNC machines can achieve tolerances as tight as ±0.002mm (±0.00008 inches). Precision is maintained through high-rigidity setups, tool path optimization, and in-process measurement systems.
• Broad Material Compatibility
CNC machining supports materials like aluminum, stainless steel, brass, titanium, plastics (e.g., POM, PEEK), and exotic alloys. Each is selected based on mechanical, thermal, and cosmetic requirements.
• Complex Geometries
Multi-axis CNC machines enable production of intricate 3D shapes, undercuts, threads, curved features, and parts with mixed contours — all within tight tolerances and smooth surface finishes.
• Flexible Batch Sizes
Whether it’s a single prototype or full production run, CNC machining provides high-quality parts without the need for expensive molds or tooling, offering low lead times and agile manufacturing.
Common CNC Machining Processes
- Milling: Uses rotating cutters to remove material from flat and contoured surfaces in 3-, 4-, or 5-axis operations.
- Turning: Rotates the workpiece while a cutting tool shapes cylindrical or conical forms, often used for shafts and bushings.
- Drilling: Precisely creates holes and internal threads of varying depths and diameters.
- Tapping: Forms internal threads with high positional accuracy and consistency.
- Boring: Enlarges or finishes pre-existing holes to achieve high dimensional accuracy.
- Thread Milling: Produces precise and durable external or internal threads with superior chip evacuation.
