CNC Turning and the Production of Different Types of Rivets(cnc laser cutting Phoebe)

CNC (Computer Numerical Control) machining has revolutionized the manufacturing industry, providing high precision mechanics in a wide range of applications. One such application is CNC turning which involves rotational cutting or drilling actions to create symmetrical products such as bolts, shafts, and an impressive array of rivets. The process can accurately produce different types of rivets with varying shapes and sizes depending on specific requirements.

Riveting is one of the oldest known methods of joining materials together. Despite technological advancements, rivets still find essential uses in many sectors such as construction, mechanical engineering, aircraft assembly, among others due to their robustness and reliability. The type of rivet used often depends on the required strength, material being joined, and cost considerations.

Among the variety, some common types of rivets include blind rivets, solid rivets, semi-tubular rivets, tubular rivets, split rivets, and drive rivets – all of which can be effectively produced using CNC turning. This article provides insights on what CNC turning is about and how it aids in producing these varied types of rivets.

CNC Turning Explained:

In its basic form, CNC turning involves fixing a block of material onto a chuck- a type of clamp that holds objects with radial symmetry along a rotating axis. A cutting tool then moves in a linear motion to cut away unnecessary material from the work pieces whilst they rotate at high speed. With computer programming overseeing the entire operation, this process ensures high repeatability and conformity to strict dimensional tolerances.

Production of Various Types of Rivets Using CNC Turning:

1. Blind Rivets: These are commonly known as ‘pop’ rivets. They’re tubular, comprised of a mandrel through the center, and applied where access to the joint line only available from one side. In CNC turning, the raw metal bar is shaped into a hollow tube with one end flared out to make the rivet head. A mandrel is then inserted through the hollow center.

2. Solid Rivets: These are one of the oldest and most widely used types, often utilized for heavy-duty applications like aircraft panels and structures. In CNC machining process, the solid shafts are turned from round metal bars with a pre-made head formed at the top.

3. Semi-Tubular Rivets: They offer a lower setting force than solid ones. The manufacturing process in a CNC machine involves shaping original metal rods into solid heads on one end with an extended partially hollow body on the other.

4. Tubular Rivets: These have a cylindrical shape with a head on one side and hollow opposite end. To manufacture these with CNC turning, it will involve producing tubes with distinct heads using precise cutting and carving actions.

5. Split Rivets: Their unique feature is their split or bifurcated shank that separates under pressure to form legs similar to staples. CNC lathe would precisely cut splits at the tail ends.

6. Drive Rivets: These are simple devices with a flat, flanged post and a fastener that’s driven down by a hammer. Manufacturing via CNC turning needs provide accurate shaping of the flat-head whilst preserving the integrity of the shaft.

In summary, CNC turning, due to its high precision, repeatability, and versatility, plays a significant role in shaping our world as we know it today. Producing various types of rivets used in different industries is just one application among endless possibilities offered by this technology.
