Types of CNC Milling
Vertical Milling
A milling table sits below a vertically-oriented spindle, moving along X and Y axes to shape parts. Ideal for small to medium-sized workpieces.
Horizontal Milling
The spindle rotates horizontally, removing large amounts of material efficiently. Best for heavy or long parts with continuous cutting.
Face Milling
Cutter rotates perpendicular to the workpiece surface, producing flat surfaces and high-quality finishes. Works with vertical or horizontal mills.
Plain Milling
Cutter rotates parallel to the workpiece surface for deeper cuts over large areas. Fine and coarse cutters optimize detail and speed.
Angular Milling
Cutter rotates at an angle to the surface, enabling grooves, chamfers, and other angled features with precision.
Form Milling
Specialized cutters shape irregular, curved, or complex surfaces, including concave, hemispherical, and semi-circular parts.
Yijiang Advantages
Complex Geometry, Fully Machined
✅ High Precision & Accuracy: CNC milling is controlled by computer programs derived from 3D CAD designs, ensuring extremely low tolerance and consistent accuracy—even for intricate geometries.
✅ High Productivity: Automated CNC processes allow for large-scale production while maintaining consistent quality and surface finish. Ideal for both prototype runs and full-scale manufacturing.
✅ Labor Efficiency: CNC milling reduces manual labor requirements. Machines operate at high spindle speeds, achieving output levels unattainable by manual machining.
✅ Cost-Effective & Reliable: Even with complex parts, CNC milling minimizes setup errors and rework, ensuring reliable production while controlling costs.
