In the world of machining and manufacturing, two vital components are often mentioned hand in hand – Computer Numerical Control (CNC) turning and rivets. Both play a critical role in different areas of production, but their functions and capabilities vary greatly. In this article, we will delve deeper into CNC turning, explore its applications, and learn about the various types of rivets used across industries.
CNC Turning Explained
At the core of many manufacturing procedures is CNC turning, a process that uses computer-controlled machines to produce precision parts. The term ‘turning’ denotes how the material block or workpiece spins while a cutting tool moves around it, shaving off excess materials according to the pre-programmed design instructions. This rotation enables the machine to cut the material accurately and yield a product with high-quality finishes.
How CNC Turning Works
A CNC turning machine holds a cylindrical piece of metal or other suitable material while rotating it at varying speeds. As this happens, stationary tools chip away at the material to shape it to specific dimensions. Through an activated command prompt, the operator can program these highly efficient machines with precise measurements for repeatable accuracy.
In essence, think of the work-piece as clay on a potter’s wheel, the potter being the computer program carrying out your desired commands. The result is a well-crafted part with detailed contours, tight tolerances, and complex geometries that would be difficult to achieve manually.
Types of Rivets
Rivets are central components used to fasten together two or more pieces permanently. While they might appear simple, there exists a wide array of rivet types serving in various applications. Here’s a closer look at some popular ones:
1. Solid Rivets: These are one of the oldest and most reliable types. They consist of a solid shaft with a head at one end, and upon installation, the tail end is deformed to hold everything tightly together. Perfect for heavy load applications.
2. Blind Rivets: Also known as pop rivets, blind rivets are designed for installations where only one side is accessible. They have a hollow stem and include a setting mandrel that pulls the body up during installation, causing it to buckle behind the base material.
3. Semi-tubular Rivets: Semi-tubular rivets feature a partially hollow shank that decreases the force needed for application. When driven in, the partially hollow rivet conforms to the surrounding hole and forms another “head,” creating a secure joint.
4. Structural Rivets: These rivets generally have higher shear and tensile strengths than other types. Useful for heavy-duty applications like constructing buildings, bridges, and aircraft.
5. Drive Rivets: A type of blind rivet, drive rivets have a short mandrel protruding from the head that is driven in with a hammer to flare out the end inserted into the hole. It makes installation quick and easy.
Both CNC turning machines and different types of rivets contribute immensely to today’s manufacturing sector. Without them, producing various intricate components for diverse industrial applcations would not be possible. As technology continues to evolve, these methods and components promise even greater efficiency, leading us towards a future of limitless potential in manufacturing processes.
