Introduction to CNC Countersunk Washer Machining
CNC countersunk washer machining is a precision manufacturing process for producing washers with a countersunk (counterbore) recess, designed to fit fasteners like screws or bolts flush with the surface.
The process typically uses CNC milling or turning machines. First, CAD software designs the washer's dimensions-outer diameter, inner hole, and counterbore depth/diameter. CAM software converts this to G-code, guiding the machine's tools.
Setup involves securing the material (often metals like steel or aluminum) in a fixture. A drill or end mill first creates the central hole, then a counterbore tool cuts the recess, ensuring precise alignment.
Advantages include high accuracy (tolerances ±0.02mm), consistent batch production, and compatibility with various materials. Applications span automotive, machinery, and construction, where flush, secure fastenings are critical. CNC automation minimizes errors, making it ideal for both small prototypes and large-scale production.
