CNC precision machining is a manufacturing process that uses computer-controlled machines to perform precise operations on raw materials. In the production of fasteners, CNC machines are used to process fastener components such as screws, bolts, nuts, washers, etc., through precise cutting, tapping and surface treatment to ensure that each fastener meets the required size, thread specifications and surface quality. Because CNC technology provides a high level of precision, it is ideal for manufacturing high-standard fasteners, especially for applications that require close tolerances.
