Fasteners are essential components that play a crucial role in various industries, especially in CNC machining. CNC (Computer Numerical Control) machining is a manufacturing process where computers control machines to create precise and intricate parts. However, without the right fasteners, these parts cannot be securely held together. In this article, we will delve into different types of fasteners commonly utilized in CNC machining.
Screws are one of the most fundamental types of fasteners used in CNC machining. They consist of a threaded shaft with a head on one end. The threaded portion allows them to be screwed into corresponding holes or pre-tapped openings. These devices offer excellent tensile strength, making them ideal for holding various materials together. Various screw types include machine screws, self-tapping screws, and wood screws, each suited to specific material requirements and joining techniques.
Bolts closely resemble screws but have some distinguishing characteristics. Unlike screws, bolts do not contain pre-formed threads; instead, they require nuts to secure two materials. Bolts typically feature a larger diameter and often possess smooth shanks with no threading along their entire length. Due to their strength, bolts find extensive use in heavy applications such as automotive and aerospace industries where high levels of vibration or dynamic forces occur.
Nuts are an integral component used in conjunction with bolts to join materials together. They come in various shapes and sizes but generally comprise an internally threaded hole. This hole allows engagement with the external threading of bolts, creating a secure connection. Just like other fasteners, nuts also have diverse variations such as hex nuts, wing nuts, and lock nuts, providing varied functionalities and ease of use.
Washers are thin circular discs placed between fasteners and surfaces being joined. Their purpose primarily involves distributing the load evenly over a larger surface area, preventing damage to the materials being joined or fastening components. They also provide improved stability and ensure that fasteners remain securely tightened for extended periods. Common types of washers include flat washers, lock washers, and spring washers.
Rivets are permanent fasteners widely used in CNC machining. These cylindrical metal pins feature a head on one end and formless threads on the other. When installed correctly, they permanently connect two or more parts by deforming the unthreaded shank during installation, creating a secure bond. Rivets work exceptionally well when joining dissimilar materials or where welding is impractical or undesired.
6. Clips and Clamps:
Clips and clamps serve as temporary fastening devices typically used during assembly or machining processes. They temporarily secure components in place, allowing subsequent operations without interfering with their accessibility. Clips may be reusable alternatives like C-clips and E-clips, while clamps encompass various types such as toggle clamps or pipe clamps, each designed for specific requirements.
Fasteners are an indispensable part of CNC machining, ensuring precise and reliable connections between components. This article shed light on commonly used fastener types within the realm of CNC machining, including screws, bolts, nuts, washers, rivets, clips, and clamps. Understanding the functions and capabilities of these fasteners plays a vital role in achieving successful results in CNC machining projects. Always consider the material properties, application requirements, and tensile strength needs before selecting the appropriate fasteners for your project. CNC Milling
