CNC turning is a fundamental part of the manufacturing industry that plays an essential role in creating several different components such as screws, rods, hubcaps and more. When it comes to fastening parts together permanently or temporarily, rivets are a go-to option and come in various types suitable for distinct applications.
CNC turning involves subtractive manufacturing where material is removed from a workpiece while it rotates rapidly against a cutting tool. This process contrasts with additive methods like 3D printing where material is added layer by layer to create a final product. With unique features such as high precision, cost-effectiveness, and repeatability, CNC machines have become invaluable tools in multiple industries, including automotive, aerospace, electronics, and many others.
A significant advantage of using CNC (Computer Numerical Control) turning centers over traditional lathes is their capability to deliver highly accurate products consistently over extended periods. Powered by sophisticated software programs, these machines follow intricate instructions without manual intervention, avoiding human errors during repetitive tasks. Although operating a CNC machine requires skilled workers, once set up correctly, the device can run autonomously, increasing productivity and delivering precise outputs every time.
The production procedure within CNC turning involves feeding concise instructions into the computer system controlling the machines. A CAD (Computer-Aided Design) model is created for the component needing fabrication. The design is then converted into numerical code understood by the machine. Using this code, the CNC machine adjusts its working parameters to meet the specific requirements, allowing well-detailed customization on each part produced.
Rivets, another key element in machining and manufacturing, play an integral role when joining pieces of metal and other materials together. They remain secure under situations involving vibrations or movements which make them ideal for aircraft, bridges, and heavy machinery construction.
There are several types of rivets, but we will focus primarily on three common types: solid, semi-tubular, and blind rivets.
1. Solid Rivets: Commonly used in the aerospace industry, these are the strongest type of rivet available. They consist of a smooth cylindrical shaft with a head at one end. Once installed, the other side is deformed using a riveting hammer or pneumatic tool, creating another ‘head,’ securing the two parts together.
2. Semi-Tubular Rivets: These rivets have a hole at the end opposite to the head. Although not as strong as solid rivets, they’re easier to install and typically used when shear strength is not the primary requirement but where lightweight, less driving force during installation or reduced damage to the assembly materials matters.
3. Blind Rivets: Also known as “pop” rivets, these are easy to install from just one side of the workpiece making them perfect for areas where access is limited. The rivet’s mandrel is pulled back into the rivet body expanding it and forming a second ‘head’ on the underside which keeps the fastened materials securely together.
Understanding the distinct types of rivets can help manufacturers decide what kind of fastener will be best for each specific application. Just like choosing the right CNC program to produce an item, selecting the most suitable rivet type significantly impacts the overall quality and functionality of the final product. From high-precision CNC turning operations through to robust, secure connections made by rivets – mastery over these processes is crucial within advanced modern manufacturing. Combining these elements effectively leads to higher efficiency, more reliable products and improved bottom line profitability.
