Rivets are a common mechanical fastener used in many manufacturing applications. They consist of a cylindrical shaft and head that is inserted through holes in two or more pieces of material. The shaft is then deformed on the opposite side to create a permanent mechanical bond. Rivets come in a variety of styles, sizes and materials to suit different needs.
For companies that rely on rivets in their products, producing consistent, high quality rivets is essential. Using computer numerical control (CNC) machines in the rivet manufacturing process enables precise control over the riveting process and results in superior rivet quality and consistency.
Benefits of CNC Machined Rivets
There are several key benefits to using CNC machines to produce rivets rather than relying solely on manual processes:
- Improved consistency - CNC machines perform each step of the riveting process the same way every time, removing variability between parts. This results in uniform rivet dimensions, head profiles, shaft deformation and overall quality.
- Enhanced precision - CNC machines allow for tighter tolerances than manual fabrication methods. Rivet lengths, diameters and other critical dimensions can be held to within 0.001 inches. This reduces rejects and improves product reliability.
- Faster production - CNC automation increases throughput compared to manual riveting. More rivets can be produced per hour, enabling manufacturers to meet higher production volumes.
- Flexible processing - CNC programs can be easily adjusted to handle different rivet sizes and designs. Quick changeovers allow a CNC machine to go from one rivet specification to another efficiently.
- Worker safety - CNC machines perform dangerous riveting steps like hot forming automatically, removing workers from hazards. This creates a safer production environment.
CNC Rivet Production Process
Producing CNC machined rivets involves several key steps:
1. Raw material preparation - The process starts with rod or wire stock of the desired rivet material, typically steel, aluminum, titanium or copper alloys. The raw material must have a precise diameter to ensure consistency of the finished rivet shank.
2. Cutting blanks - The rod stock is fed into the CNC machine where it is cut to length by precision carbide cutting tools. These blanks become the rivet shank and head. Blanks may be cut one at a time or in multiples.
3. Heading - In this step the rivet head is formed on one end. The blank is struck by a die in the CNC machine at high force, molding the material into the desired head profile. Concave, flat and countersunk head shapes can be produced.
4. Shank machining - Next the CNC machine will machine the rivet shank to achieve the required diameter and surface finish. This may involve turning, grinding and other processes.
5. Heat treatment - For enhanced strength, rivets may undergo heat treatment like quenching or tempering via CNC-controlled ovens.
6. Deburring - Any residual burrs or sharp edges are removed by tumbling or vibratory finishing. This prevents damage during rivet installation.
7. Head stamping - Finally, head marking like manufacturer, material and part numbers are stamped via CNC-actuated marking presses.
8. Quality assurance - Dimensional inspection, material testing and other quality checks are conducted to ensure the rivets meet all specifications before shipment.
As this overview illustrates, CNC machines are integral to modern rivet manufacturing. By automating and controlling each production step, they enable fast, consistent, high quality results not attainable with manual methods alone. Companies investing in CNC rivet production equipment reap the benefits through improved product quality, manufacturing efficiency and customer satisfaction. Whether producing rivets in small batches for custom aircraft applications or high volumes for the automotive industry, CNC machining is the clear choice for reliability, precision and performance.
