CNC machining offers key advantages over 3D printing, injection molding, and laser cutting:

It is fast and cost-effective for simple parts, such as base plates with holes or grooves. CNC machines can achieve tight tolerances of ±0.01 mm and deliver smooth surface finishes down to Ra 0.8, making them ideal for painting or anodizing. They also accommodate a wide range of part sizes—from large components up to 600 mm × 3,000 mm to tiny features cut with 0.05 mm tools on precision 5-axis mills.
