Rivets are a crucial fastening component in many manufacturing and fabrication processes. In CNC (computer numerical control) machining, rivets serve important functions in joining metal components securely and efficiently. Here we'll explore some of the top uses and benefits of incorporating rivets in CNC work:
Aircraft and Aerospace Applications
The aerospace industry has relied on rivets for decades to assemble airplane fuselages, wings, and other components. Rivets create strong, reliable joints that can withstand tremendous forces and repeated stress. CNC machining allows rivets to be produced with precision and consistency for aviation purposes. Some common aircraft applications include:
- Fuselage assembly - Hundreds of thousands of rivets may be used to join aluminum fuselage skins on an airplane. CNC machining enables each rivet hole to be drilled accurately for uniform fit.
- Wing assembly - Rivets are used extensively in wing construction to connect spars, ribs, and skin panels. CNC cut wing ribs are riveted to the wing spars for maximum strength.
- Engine nacelles and pylons - Rivets secure engine housings and pylons firmly to the wing and fuselage structures on aircraft. CNC machined rivet holes align perfectly for smooth engine integration.
- Flight control surfaces - Flaps, slats, spoilers, and other moving surfaces use rows of rivets for hinged attachment and rotation. CNC precision permits tight tolerance riveting for slippage-free movement.
- Major airframe joints - Major fuselage sections are joined with hundreds of rivets along the junction line. CNC drilled rivet patterns allow complete airframe integration.
- Repairs and maintenance - CNC cut rivets are used extensively in aircraft maintenance and repair jobs. Hole sizing and alignment are critical for successful rivet replacement.
Aviation manufacturers rely on CNC capabilities to drill, countersink, and install rivets with the precision needed for airworthiness. Robotic riveting workcells also employ CNC for mass rivet installation.
Transportation Applications
Beyond aircraft, rivets are important in the manufacture of trucks, buses, railcars, and other transportation machinery. Some examples:
- Truck trailer assembly - CNC machined aluminum rivets are ideal for joining extruded panels and connecting trailer structural components. Robot riveting automation is commonly used.
- Train and subway car construction - Rivets assemble aluminum and stainless steel car body shells for strength and durability. CNC permits mass production of cars using rivets.
- Ship hulls and decks - The marine industry makes extensive use of rivets to construct ship hull and deck components. CNC drilled holes ensure leakproof joints.
- Automotive manufacturing - Cars use thousands of rivets to attach body panels, dashboards, trim, and other interior components. Robot riveting with CNC hole alignment is standard.

- Transportation repairs - Cracked or damaged components on buses, railcars, ships, and other vehicles are often repaired using CNC machined replacement rivets. Hole alignment is critical.
CNC allows riveting operations to be optimized for mass production across transportation modes. Robot automation further improves cycle times for cost-efficiency.
Construction and Infrastructure Uses
Beyond manufacturing, rivets are commonly used in building construction, bridges, dams, and civil structures. Some examples of CNC riveting include:
- Steel structure assembly - Buildings, cranes, bridges, radio towers, and platforms often use CNC machined steel rivets for structural connections. Superior strength and durability.
- Aluminum scaffolding and ladders - Extruded aluminum tubing is riveted together to produce scaffold frameworks, catwalks, and specialty ladders. CNC hole sizing ensures tight joint tolerances for stability and safety.
- Water tank and silo construction - Large capacity storage tanks and silos utilize CNC machined rivets around the circumference to create leakproof seams. Rivets handle vibration and shifting loads.
- Pipe hangers, braces, and supports - Rivets provide a quick connecting method for suspending pipes, conduit, cable trays, and ductwork. CNC machining ensures uniform hanger sizing and fit.
- Window assembly in curtain walls - Metal frames use rivets at the corners for strength when installing glass windows in tall buildings. CNC aligned holes prevent glass slippage.
- Dam spillway gates - Heavy flood gates are assembled using CNC machined rivets capable of withstanding tremendous hydrostatic forces from rushing water.
CNC riveting technology allows efficient, mass production of construction components with consistent quality and structural integrity.
General Manufacturing Applications
Across general manufacturing, CNC riveting offers fast, simple, and rugged joining of metal parts. Common applications include:
- Appliances and electronics - Sheet metal chassis use rivets for low-cost fastening. CNC manufactured rivets improve quality and speed.
- Food service equipment - Stainless steel restaurant equipment like tables, sinks, and shelves are riveted for durability and cleanliness. CNC permits high volume production.
- Retail displays and fixtures - Rivets provide inexpensive but sturdy fastening for retail racks, shelving units, sign frames, and display cases. CNC allows mass customization.
- Furniture assembly - Chairs, tables, cabinets, and stadium seating rely on CNC machined rivets for strength, ease of assembly, and attractive appearance.
- Agricultural equipment - Durability and vibration resistance make rivets ideal for connecting farm equipment frames, implements, and accessories. CNC maintains precision.
- Gym and playground equipment - Rugged rivets are commonly used to assemble gym equipment frames, bleachers, and park structures. CNC optimizes fit and hole alignment.
For virtually any manufacturing application where metal-to-metal joining is needed, CNC riveting provides and efficient, high quality fastening solution. Continued advancements in CNC and automation will further improve rivet manufacturing productivity and capabilities. CNC Milling
