CNC machining parts refer to components produced using CNC machines, which are operated by pre-programmed computer software. These machines can process a wide range of materials, including metals (aluminum, steel, titanium), plastics (acrylic, POM, ABS), and composites, to create intricate and high-precision parts. CNC machining is ideal for producing both one-off prototypes and high-volume production runs.
Ultra-Tight Tolerances: Standard machining to ±0.05mm, with high-precision capabilities reaching ±0.01mm for critical dimensions
Advanced Equipment: Utilization of multi-axis CNC machining centers (3/4/5-axis), Swiss-type lathes, and milling-turning compound systems
Surface Excellence: Achievable surface roughness from Ra 0.8μm to Ra 6.3μm, with mirror polishing options available
