What Is CNC Machining?
CNC machining is a subtractive manufacturing process that uses computer-controlled machines to remove material from solid blocks and create high-precision parts. It is widely used for components requiring tight tolerances, excellent surface finishes, and reliable mechanical performance.
CNC machining is ideal for:
• Functional prototypes
• Custom mechanical components
• Low-to-medium volume production
• Complex geometries requiring high accuracy
