CNC machining has revolutionized the manufacturing industry with its precision and efficiency. An integral part of this process is the use of fasteners, which are essential for securely joining different components together. In this article, we will delve into the various types of fasteners commonly used in CNC machining and explore their applications.
Screws play a crucial role in CNC machining, providing strong and reliable connections. They come in different forms, such as machine screws, self-tapping screws, and set screws. Machine screws feature uniform threads and secure objects acting as a nut when paired with corresponding threaded holes. Self-tapping screws create internal threads within the materials they're driven into, eliminating the need for pre-drilled holes. Set screws have no head and are primarily used to secure rotating parts on shafts.
Bolts are similar to screws but differ in their intended application. They typically require nuts to provide a firm connection. Hex bolts, carriage bolts, and eye bolts are some commonly used varieties. Hex bolts have six-sided heads and can be tightened using a wrench or socket. Carriage bolts possess smooth, domed heads and square-shaped necks that prevent turning during installation. Eye bolts have a looped end, allowing them to serve as attachment points.
Nuts are threaded fasteners that work in conjunction with screws or bolts. Commonly encountered types include hex nuts, lock nuts, and wing nuts. Hex nuts have six flat sides and can be easily tightened or loosened using a wrench or pliers. Lock nuts boast additional features like nylon inserts or deformed threads to enhance resistance against vibration or loosening. Wing nuts, with their butterfly-like wings, enable manual tightening without the need for tools.
Rivets are fasteners often used in CNC machining to permanently join two or more materials together. They consist of a cylindrical body with a head on one end and a tail on the other. Upon insertion, the tail is deformed to create a second head, effectively locking the pieces in place. Blind rivets are especially useful when access to both sides of the workpiece is limited.
Threaded inserts are essential components for creating reliable and durable threaded connections in CNC machining. These inserts add reinforcement to soft or thin materials like plastics or wood. They come in various styles, including helical inserts, key-locking inserts, and press-fit inserts. Helical inserts, commonly known as coil or wire inserts, provide internal threads that enhance resistance against wear and loosening. Key-locking inserts possess keys around the interior perimeter, adding extra resistance to torque. Press-fit inserts are inserted into pre-drilled holes using heat or force without any external threading required.
Fasteners play a vital role in the success of CNC machining processes by ensuring stability, durability, and functionality. By understanding the different types of fasteners available, manufacturers can make informed decisions while selecting the most suitable option for their specific applications. The diverse range of screws, bolts, nuts, rivets, and inserts allows for versatility in joining various materials securely, making CNC machining an efficient and cost-effective manufacturing solution.
