Rivets are a crucial component in many manufacturing and engineering applications. Especially in computer numerical control (CNC) manufacturing, using high quality rivets ensures strength, durability, and safety in the final product. Here is an overview on rivets, their manufacturing process, and why using the best quality rivets is critical for CNC production.
What are Rivets?
A rivet is a mechanical fastener that connects two or more materials by inserting its shank through holes in the materials and deforming the shank to form a head. The rivet shank expands when being installed to form a tight connection that holds the materials together. Rivets come in various head shapes, shank diameters, and materials to accommodate different applications and manufacturing needs.
Common Uses of Rivets
Rivets have been used since ancient times in construction and manufacturing. Today, rivets still play a vital role in many industries including:
- Aerospace - rivets are extensively used in aircraft assembly to join fuselage skins, wings, engine components, etc. Aerospace rivets are designed for light weight and high strength.
- Automotive - rivets join body panels, frames, brackets, and other automotive parts that handle vibration and load stresses. Automotive rivets emphasize corrosion resistance.
- Appliances - household appliances like washers, dryers, and refrigerators rely on rivets to assemble cases and internal parts. Appliance rivets focus on economy and ease of installation.
- Electronics - electronics manufacturers use specialty rivets to fasten internal components in products like cellphones, computers, medical devices, and more. These rivets provide electrical conductivity and thermal properties.
- Construction - steel rivets are common for connecting structural steel. Aluminum and stainless steel rivets assemble cranes, bridges, storage tanks, and mechanical systems. Construction rivets enable heavy load capacity.
As these examples illustrate, rivets serve the vital function of creating strong, reliable joints in manufacturing across industries.
CNC Manufacturing Overview
CNC (Computer Numerical Control) manufacturing utilizes programmable machine tools to fabricate components with automation and precision. Common CNC machines include lathes, mills, routers, grinders, lasers, waterjets, punches, press brakes, and more. Parts are machined from raw material blocks according to CAD/CAM designs using custom toolpaths and movements controlled by the CNC system.
Benefits of CNC manufacturing include:
- High tolerances and repeatability for precision parts
- Ability to produce complex geometries unachievable manually
- Fast production runs once initial programming is complete
- Minimal setup labor compared to manual methods
- Flexible manufacturing with quick design or product changes
- Reduced material waste from automated material removal
- Increased manufacturing consistency and quality control
CNC technology enables efficient, automated fabrication of components across nearly every manufacturing sector.
Importance of Quality Rivets in CNC Production
Using high quality rivets is critical for CNC-produced parts for several reasons:
Strength & Durability
The integrity of riveted joints is only as strong as the rivets themselves. Weak or defective rivets lead to joint failure and part breakage in service. CNC requires rivets that maintain clamping force and don't corrode, fatigue, or creep under sustained loads and environments. Aircraft-grade aluminum alloy rivets offer superb strength for structural assemblies. Hardened steel rivets withstand tremendous shear and tensile stresses. Using the optimal rivet strength and material prevents joint slippage or failure during part function.
Precise Dimensions
CNC machining demands consistency and tight tolerances. Rivets must match their hole sizes precisely to achieve a flush fit and optimum fastening. Loose or undersized rivets cannot fill holes correctly and result in poor connections. Oversized rivets won't fit the holes at all. Reputable rivet manufacturers control diameters, lengths, head dimensions, and other attributes to exacting standards best suited for CNC work. This aids rivet driving and clinching during automated assembly.
Reliable Feeding
CNC relies on tool changers and feeder systems to supply rivets automatically during production. Rivets must feed smoothly without jamming to avoid machine downtime. Feeding issues like stuck rivets, tangling in barrels, or irregular orientations will halt manufacturing. Well-engineered rivets have properphysical attributes and coatings to flow freely without complications. Vibratory bowl feeders help orient rivets correctly as they enter the machinery.
Easy Installation
CNC requires fast, simple rivet installation to maximize efficiency. Quality rivets are designed for effortless joining using standard drivers, inserts, anvils, upsetters, and other tooling. Their physical properties allow One-shot, pull-through, or other low-force installation methods. Specialized drive/set systems like Huck bolts further optimize automation. Minimal drive force and smoothing setting reduces wear on delicate aircraft or electronics assemblies. Quick installation also prevents work hardening or deformation around holes.
Leak and Corrosion Resistance
Joints fastened by quality rivets should resist leaks, weather effects, and harsh operating environments. Leaking fluids lead to dangerous malfunctions on aircraft or pressure vessels. Corrosion degrades riveted structures like bridges over time. The best rivets have coatings or inherent material properties to prevent moisture intrusion, galvanic corrosion, oxidation, and other effects depending on the application. Plastic or composite rivets avoid metal corrosion issues altogether in some uses.
Electrical Conductivity
Certain applications require rivets that conduct electricity across joints. Aluminum rivets with magnesium oxide insulation offer this benefit for aircraft lighting systems. Copper and copper alloy rivets also provide excellent conductivity while resisting corrosion. Electrically insulating rivets are preferable for other scenarios. Carefully selecting rivet materials that either conduct or insulate electricity is vital where this factor matters.
Cost Effectiveness
To maximize manufacturing efficiency, CNC production needs affordable riveting solutions without compromising quality. While exotic alloys and proprietary designs exist for extreme applications, common CNC jobs use standard, economical rivets. Simple one-piece rivets keep material costs low. Basic aluminum, steel, and copper alloys satisfy strength and conductivity needs at scale. Secondary operations like plating, coating, and anodizing further enhance rivet properties cost-effectively. Using common, high-volume rivets helps optimize production costs.
Summary
Installing quality rivets is essential for optimizing any CNC manufacturing application. Their physical attributes and consistency directly determine the safety and reliability of riveted assemblies. Reputable brands offering accurate dimensions, high strength materials, reliable feeding, quick installation, and affordable prices should be selected to produce durable, high-quality riveted products via CNC methods. With sound design and processing, CNC-fabricated components benefit tremendously by utilizing the best possible rivets available on the market today. CNC Milling
