Rivets are an essential fastening component for many manufacturing and fabrication projects. For shops using computer numerical control (CNC) machines, having a reliable source of high-quality rivets can make all the difference in achieving precision results. In this article, we'll look at what to consider when selecting rivets for use in CNC machines as well as the manufacturing process used to produce quality rivets suited for automated fabrication.
What Makes a Good Rivet for CNC Machines?
There are several key factors that determine how well a rivet will perform in an automated CNC process:
Material - Aircraft-grade aluminum is a popular choice for CNC rivets due to its strength, light weight, and corrosion resistance. Steel, copper, and various alloys are also commonly used. The material must be compatible with the parts being joined and able to withstand applied stresses.
Head Style - Countersunk, round head, and flush rivets are standard options. The head shape impacts how the rivet sits within a hole and determines the appearance of the finished joint. Machine head styling must be precisely controlled.
Dimensional Consistency - CNC machines demand rivets that are identically sized and have minimal variability between pieces. Diameter, head height, chamfer, and other dimensions need to be maintained within very tight tolerances.
Grip Range - Multiple grip lengths allow one rivet type to accommodate different material stacked heights during assembly. Wide grip range rivets simplify CNC processes and part kits.
Break Mandrel - Also called breakstem, these rivets have a mandrel that snaps off evenly at a pre-set length when installed. This delivers clean results with no messy shank leftover.
How Are Quality Rivets Made for CNC Use?
The production of rivets suited for automated fabrication involves precision machining and careful control of the manufacturing environment. Here is an overview of how quality control factors into the process:
Raw Material - Aircraft-grade aluminum rod, bar, or extruded profiles must meet composition standards for elements like magnesium and iron. Material certification confirms the elemental makeup. Strict incoming inspection checks for surface flaws.
CNC machining - Computer-controlled turning centers and multi-axis machining centers shape the rivet blanks with exacting tolerance levels. Programmed tool paths and quality-monitored machining ensure consistency.
Head Forming - The rivet head shape and machine styling are created using cold forming techniques. Head dimensions are precision controlled with forming presses equipped for high-volume production.
Mandrel Insertion - On break mandrel designs, the mandrel wire is inserted into the rivet body according to pre-programmed insertion settings that control depth and placement.
Heat Treatment - To increase rivet hardness and shear strength, certain alloys are put through a heat treat process immediately after machining. This additionally improves dimensional stability.
Plating - Zinc and other surface platings can be added to inhibit corrosion and enhance wear properties. This is often done on rivets made from steel.
Quality Assurance - Extensive inspection procedures verify that completed rivets are within tolerance on diameter, head style, grip length, mandrel projection, and all critical dimensions. Testing ensures performance consistency.
Packaging - Rivets are carefully packaged based on alloy material to avoid cross-contamination from other metals during storage and shipping. Proper packaging also helps preserve surface finishes.
By understanding the complete manufacturing process for quality CNC rivets, buyers can select products that will function optimally during automated fabrication. Partnering with an experienced industrial rivet supplier is the best way ensure access to premium rivets purpose-built for precision machining applications. With a focus on quality, your CNC program will benefit from smooth and reliable rivet installation.
The Key Uses of Rivets in CNC Machining
Computer controlled riveting offers many advantages that make it a staple process for applications like:
Aircraft Manufacturing - CNC rivet installation produces airframe and component assemblies that meet stringent aviation quality standards. Aerospace-grade rivets are designed specifically for automated fabrication.
Metalworking - From motorcycles to agricultural equipment, manufacturers of metal end products rely on CNC riveting for mass production of frames, enclosures, platforms, and more. Properly specified rivets join parts accurately and securely.
Electronics Enclosure - Rivets allow sheet metal enclosures for electronics to be quickly assembled by CNC machining centers. The process is fast, consistent, and economical compared to welding or hardware.
Appliance Manufacturing - Household appliance makers take advantage of automated riveting to assemble external cases as well as internal frameworks and brackets. The precision joins CNC riveting provides are critical.
Automotive Fabrication - CNC technology produces riveted frames, body panels, interior components, and chassis parts for vehicles with repeatability and efficiency. Automotive-grade rivets meet the demands.
HVAC Ducting - For heating, ventilation, and air conditioning duct work, CNC machines excel at joining sheet metal sections with rows of rivets. Riveting creates durable, air-tight seals rapidly.
The common thread among these examples is that CNC riveting provides a quality, reliable assembly solution. Done right, it's fast, versatile, and able to handle high production volumes. With application-matched rivets, shops can gain all the benefits this process has to offer.
Critical CNC Riveting Process Considerations
To consistently produce quality riveted assemblies via CNC operation, shops should address these key process factors:
Rivet Fed Machines - Using automated feeder equipment ensures a steady supply of rivets to the CNC spindle for rapid production. Vibratory bowl and tape feeding systems are common options.
Nose Assemblies - Precision machined shank, collar, and nose pieces properly guide and support the rivet so it aligns with mating hole locations and avoids twisting.
Correct Tool Pressure - Programmed rivet setting force parameters must generate adequate pressure and stroke to form heads without causing rivet cracking or deforming parts.
Hole Alignment - Matched hole positions between stacked components prevents off-angle rivet insertion that can compromise joint integrity and appearance.
Clamping Strength - Sufficient holding strength of clamps and fixtures is necessary to resist riveting force and stop parts from shifting during installation.
Quality Inspection - Production sampling should be examined for proper rivet sizing, sufficient grip range, full head formation, mandrel breakage, and clinch lock.
With factors like these addressed, manufacturers can equip themselves to produce riveted CNC assemblies with the necessary accuracy and consistency for their application.
Ensuring Rivet Quality for Your CNC Application
There are further steps buyers can take to guarantee the quality of the rivets used in their CNC machining work cells:
Research Suppliers - Learn about suppliers’ expertise in rivets for automated fabrication. The quality processes described earlier should be in place.
Request Samples - Test prospective vendors’ products in your machining application to assess performance. Verify consistency across rivet dimensions.
Check Certifications - Ask for documentation like material certs, test reports, process control methods, and equipment calibration records that back up quality claims.
Tour Facilities - An inside look at suppliers’ machining and rivet manufacturing facilities can provide insight on their capabilities.
Confirm Inventory - Make sure your volume needs can be fulfilled without delay by assessing the supplier's stock of ready-to-ship finished goods.
Once satisfied with a supplier’s capabilities and rivet quality, buyers can work to build a partnership that keeps the CNC process running reliably over the long term.
In Summary
Rivets are a pivotal component in automated CNC fabrication. From aircraft builders to appliance manufacturers, companies count on the precision joining and efficient process results that machine-driven riveting offers. By understanding critical quality factors like material, dimensional consistency, head style, and mandrel design, buyers can select rivets optimized for automated performance. A focus on quality control during manufacturing, smart process integration, and choosing the right rivet supplier will keep any CNC application running at its riveting best. CNC Milling
