Rivets are a versatile mechanical fastener used in many manufacturing applications, including those involving computer numerical control (CNC) machining. Here is an overview of some of the main uses for rivets in CNC processes:
Aircraft and Aerospace Applications
Rivets are extensively used in the assembly of aircraft and aerospace structures. The aircraft industry was one of the early pioneering users of rivets, as they allow for the joining of light-weight aluminum alloy components in the construction of planes.
CNC machines are commonly used to drill the precise rivet holes in aircraft panels, skins, ribs, bulkheads and other parts that require riveted joins. The riveting process itself may also be automated via CNC-controlled riveting machines.
Some of the main advantages of rivets for aircraft assembly include:
- High strength-to-weight ratio - rivets add little mass but allow for strong joins. This is critical in aircraft design where weight must be minimized.
- Reliability - aircraft-grade rivets and properly executed riveted joints offer reliable long-term integrity in the high loads and stresses of flight.
- Corrosion resistance - rivet materials and platings are chosen to withstand aircraft operating environments.
- Streamlined manufacturing - automated drilling and riveting processes allow for high-precision high-volume fabrication.
- Repairability - rivets can be removed and replaced to facilitate maintenance and repairs.
Construction and Infrastructure
Beyond aerospace, rivets also frequently appear in the construction of infrastructure like bridges, cranes, transmission towers, and more. CNC machines are used to drill holes for and install hot rivets in the fabrication of robust structural frames.
Rivets in construction offer:
- High shear and tensile strength for load-bearing structures.
- Durability in outdoor weather conditions like rain, sun, and temperature extremes.
- Vibration damping - important for dynamic loads on bridges.
- Ease of inspection - loose or damaged rivets are visually apparent.
- Cost effectiveness - rivets are inexpensive compared to welds or bolts.
- No on-site heat or power required - rivets can be installed using hand tools.
Transportation and Automotive
Rivets similarly see heavy usage in vehicles, trains, ships, and other transport equipment that undergoes vibration or shock loads. CNC machining applies rivets in:
- Car, truck, and motorcycle chassis and body panels.
- Ship hulls, decks, and bulkheads.
- Railroad car frames and body construction.
- Trailers, cranes, farming equipment, and heavy machinery.
For transportation applications, benefits include:
- Vibration resistance without loosening.
- Impact and shock load strength.
- Corrosion resistance for long in-service life.
- Light weight versus welding or bolting.
- Easy to automate in mass production.
Industrial Machinery
In the production of industrial machinery, manufacturers leverage rivets to assemble durable equipment frames, casings, attachments, and components.
CNC machining is used to precisely drill rivet holes and fasten parts including:
- Mixers, crushers, grinders, and processing equipment.
- Robotics, factory automation, and handling systems.
- Agricultural, forestry, and construction machinery.
- Generators, turbines, compressors and pumps.
- Gears, couplings, sprockets, and transmission components.
Advantages of rivets in this category are:
- Strength - resist wear from vibration and kinetic loads.
- Long-lasting - outlast welds and fasteners in harsh environments.
- Reliable - won't shake loose over time.
- Economical - lower cost than exotic fastening methods.
- Easy maintenance and repair via rivet removal and replacement.
Appliances and Consumer Products
Rivets also play roles in the manufacture of appliances like refrigerators, washers, as well as electronics cases, furniture, and more consumer goods.
CNC machining applies rivets in products like:
- Computer cases, CCTV/DVR boxes, and electronics enclosures.
- Electrical junction boxes, control panels, and switchgear.
- Office furniture, shelving, and cabinetry.
- Kitchen and laundry appliances.
- Gym and exercise equipment.
- Bicycles, strollers, and other mobile equipment.
For these items, rivets allow:
- Sturdy and tamper-resistant product assembly.
- Cost-effective mechanized production.
- Trouble-free service life for consumers.
- Easy disassembly for recycling and end-of-life.
In summary, rivets serve a diverse array of applications thanks to their lightweight strength, durability, economy, and manufacturability. With computerized precision and automation, CNC machines help harness the versatility of rivets across many industries. Riveting remains a go-to mechanical fastening solution for numerous fabrication challenges. CNC Milling
