Rivets are one of the most common and versatile fasteners used in manufacturing. A rivet is a mechanical fastener that joins two or more materials by passing a metal rod through holes in the materials and deforming the free end to clamp them together. Rivets have been used for thousands of years in construction and manufacturing due to their strength, durability, and ease of installation.
With the rise of computer numerical control (CNC) machining, rivets remain an integral component in many manufacturing processes. Here are some of the top uses for rivets in CNC manufacturing:
Aircraft and Aerospace Applications
The aerospace industry relies heavily on rivets for assembling airplane fuselages, wings, and other components. Rivets create strong, permanent joints while adding very little weight. CNC machines drill perfectly aligned rivet holes into the various aluminum and titanium parts that make up airplanes. Riveting provides more shear and fatigue strength than welding thin aircraft materials while also preventing crack propagation. Aircraft require hundreds of thousands of rivets, so automated riveting systems have been developed to work in tandem with CNC machinery.
Metal Fabrication and Joining
Rivets are commonly used to assemble all types of metal fabrication products. CNC machining centers can rapidly drill consistent rivet holes into steel, aluminum, and other metals being joined. Riveting provides a fast alternative to welding or screwing various metal parts together. It also allows for modular assembly and disassembly for maintenance and part replacement. From truck bodies to industrial equipment, manufacturers rely on CNC riveting for metal fabrication projects.
Electronics Enclosure and Chassis Construction
Many electronics enclosures and chassis are held together by rivets. CNC routers excel at cutting precision slots and holes in sheet metal and plastics used for electronics housings. Rivets provide a strong mechanical attachment between panels, access plates, and other enclosure components. The rivets can be installed manually or by automated riveting systems. Riveting avoids introducing heat like welding and soldering, which could damage sensitive electronics. Rivets also withstand vibration and impacts better than screws in electronics applications.
Piping Systems
Industrial piping systems often use rivets to assemble brackets, supports, guides, and other components. CNC machining centers drill holes for rivets based on digital prototypes and models. Riveting is faster and less expensive than welding brackets onto pipes. Rivets also allow for adjusting or removing piping supports when modifications are needed. CNC automated riveting machines can install thousands of rivets to customize bracketing even on large diameter pipes. This improves safety and reliability in critical piping systems.
Automotive Manufacturing
Automotive factories rely extensively on CNC and robotic riveting to mass produce cars and trucks. Body panels, frames, doors, hoods, and roofs are commonly joined with self-piercing rivets. CNC machining centers drill holes into the sheet metal parts, often several layers thick. Then a robot applies rivets by pressing the rivet through the stack up of materials. The rivet pierces through the top layers and flares out underneath to join the parts together. Automated riveting with CNC and robots enables very high-volume riveting for automobile manufacturing.
Appliance Manufacturing
Home appliances like refrigerators, ovens, washers and dryers utilize CNC riveting in their assembly. The outer metal skins that form the doors, lids, control panels, and wrappers are traditionally joined using self-piercing rivets. CNC machines drill the rivet holes to position in the sheet metal appliance parts. Robotic riveting systems then join the parts together by inserting rivets in a matter of seconds. The automation ensures consistency and frees workers from repetitive manual tasks. Riveting also avoids exterior welding marks and allows for disassembly later for repairs if needed.
Safety and Security Equipment
From fire extinguishers to gun safes to jail cells, rivets play an important role in assembling products meant to protect lives and property. The strong and permanent joining of rivets prevents tampering or disassembling in these critical safety applications. CNC machining centers are ideal for drilling the large number of rivet holes needed in products like gun safes which require extensive riveting. Riveting also allows field repairs and modifications by simply drilling out old rivets as needed and installing new ones. The automation of CNC and robotic riveting improves the quality control compared to manual riveting.
Construction and Building
While welding has displaced some riveting in steel construction, rivets maintain extensive use for joining girders, frames, roofs, and architectural details. CNC plasma or waterjet cutting machines are commonly programmed to cut steel pieces ready for assembly with rivets. Riveting's main advantages include: speed of installation, ability to install on-site, lack of heat warping, and vibrational damping. CNC automation also enables mass production of modular building components joined with rivets for rapid on-site assembly.
Signage, Displays, and Decor
Rivets secure the letters and graphics on signs, displays, plaques, and building frontages. CNC routers machine sign materials like acrylic, aluminum, and wood by cutting out letter and logo shapes ready for mounting. Holes drilled by the CNC machines allow easy rivet installation to affix the sign letters onto backer materials. The heads of round head aluminum rivets also create visible accents and decor details. CNC automation allows relatively low volume but completely custom signage and decor to be efficiently mass produced.
Product Testing and Prototyping
Rivets serve extensively in prototyping manufacturing processes and products during testing phases. The ability to disassemble and re-rivet components makes rivets ideal for product development. CNC machining centers can quickly drill rivet holes in new product prototypes and test jigs. As changes are made, existing rivets can be removed and re-riveted in new positions as needed. Riveting also securely fastens instrumentation like sensors to prototypes during testing before final welding or adhesive methods are chosen.
Repair and Field Service
One of rivets' key advantages is the ability to be installed manually with simple hand tools, making riveting ideal for repairs in the field. Technicians can drill out old rivets and install new ones to service equipment. Portable CNC machines like robots are even bringing riveting automation to on-site construction, maintenance, and repair applications. The accessibility of riveting and modular nature of riveted designs makes rivets the choice for servicing manufactured products.
In summary, rivets remain one of the most versatile fastening solutions, made even more efficient by CNC automation. From aircraft and autos to appliances and signage, manufacturers rely on the strength of CNC-machined rivet connections in all types of materials and products. Rivets join the modern world in ways we seldom stop to notice. CNC Milling
