Rivets are a crucial fastening component in many manufacturing applications, including computer numerical control (CNC) machining. CNC machining utilizes computer-controlled equipment to automate the machining process. This advanced manufacturing technique is commonly used for high-precision metalworking in industries like aerospace, automotive, and electronics. Rivets serve an important role in CNC machining and fabricated metal products by providing a sturdy mechanical fastener to join sheet metal components.
Some of the key uses for rivets in CNC machining include:
Aircraft Assembly
The aerospace industry relies heavily on rivets for aircraft assembly. Rivets provide a lightweight and reliable fastening method to join the many sheets of aluminum that make up an airplane's fuselage and wings. CNC machining is used to drill perfectly aligned rivet holes into the aluminum parts. Then rivets are installed by automated riveting machines or by hand. Rivets create strong joints while minimizing aircraft weight, which improves fuel efficiency.
Sheet Metal Enclosures
Electronics enclosures made of sheet metal often use rivets for assembly. CNC machining processes like milling, drilling and tapping create holes in the sheet metal panels to allow for rivet installation. Rivets joining multiple panels result in rugged enclosures that protect sensitive electronic components. Rivets allow for quick assembly and disassembly for electronics service and repair.
Metal Fabrication
General metal fabrication across many industries utilizes rivets to join sheet metal components. CNC machining centers outfitted with drills create holes for rivets in parts like brackets, supports, covers and housings. Rivets provide a permanent assembly while still allowing for some flexibility and vibration dampening in the joint. Rivets are easy to install with access from only one side of a part.
Heavy Equipment & Vehicles
Construction equipment, agricultural equipment and heavy-duty vehicles rely on CNC machined parts riveted together. Excavators, tractors, bulldozers and trucks subject components to high stress and vibration. Rivets allow sheet metal parts like cabs, chassis and body panels to be securely fastened together while withstanding harsh operating environments. CNC machining ensures rivet holes are positioned accurately for proper alignment.
Piping Systems
Industrial piping systems utilize rivets to assemble support structures. CNC machining cuts angles and holes in brackets that are then riveted to tanks, pipes and other components. Rivets create strong joints to securely fasten piping runs while allowing some flexibility. CNC production of riveted brackets provides consistent quality parts.
Metal Sculptures
Artists working with CNC machining can utilize rivets in complex metal sculptures. Exotic metals like copper, brass and stainless steel can be machined, drilled and riveted together to create abstract geometric designs. Rivets join sculptural pieces while becoming part of the aesthetic. CNC allows for precision placement of hundreds of rivet holes to bring together artistic welded and machined metal pieces.
Jewelry Making
Handmade jewelry crafted from precious metals often features riveted designs. CNC machining can cut jewelry parts from sheet gold, silver, platinum, etc. and drill holes for rivets. Rivets create durable jewelry pieces that can withstand daily wear. CNC precision allows for tiny rivets that act as decorative accents in rings, bracelets, pendants and more. Jewelry makers can easily join multiple CNC machined parts with rivets.
Automotive Assembly
Automotive manufacturing relies extensively on CNC machining and rivets to mass produce cars and trucks. Sheet metal body panels, interior parts, and underbody components are drilled with rivet holes by CNC machines. Robotic riveting machines quickly insert thousands of rivets to assemble vehicles on the assembly line. The joining flexibility, vibration resistance, and corrosion resistance of rivets make them ideal for automotive assembly. CNC automation ensures rivet consistency in large volumes.
Metal Composite Panels
Rivets serve as a way to sandwich materials together, such as with modern metal composite panels. These panels consist of two thin sheets of aluminum around a thermoplastic core. CNC machined holes along the panel edges allow for installation of rivets that compress the composite materials together into a rigid, lightweight sheet. These panels save weight in transportation applications and have desired acoustic properties.
Point-of-Purchase Displays
Retail displays at the point of purchase often consist of CNC machined aluminum extrusion frames riveted together. Display panels with graphics and shelves are riveted onto the front of the frame. Rivets allow for quick assembly and disassembly of trade show booths and retail displays. CNC production ensures the rivet holes align properly for easy installation. Rivets provide sufficient strength to hold display components together securely.
In summary, rivets serve a vital role in CNC machining and manufacturing processes across many industries. The pairing of CNC precision and rivet flexibility results in high-quality finished products. From aircraft and trucks to jewelry and art, rivets join materials securely in automated or manual assembly. Continued advancement in riveting technology and CNC machining will enable faster, lower-cost manufacturing with consistent quality. CNC Milling CNC Machining
