CNC drilling is a high-precision machining process used to create accurate and repeatable holes in both metal and plastic components. Unlike manual drilling, CNC drilling uses computer-controlled systems for precise positioning and repeatability, ensuring consistent hole sizes and depth across both prototypes and production parts. This advanced process delivers clean, accurately located holes with predictable geometry, making it ideal for complex and high-accuracy applications.
CNC drilling ensures consistent hole diameter, depth, and positioning with each operation.
CNC drilling offers higher repeatability, faster production, and better precision compared to traditional manual methods.
CNC machines support various configurations, from basic straight-hole drilling to advanced multi-axis and deep-hole drilling.
