Rivets are an essential fastening component for many products produced on CNC machines. While rivets may seem simple, there are some important factors to consider when selecting rivets for use in CNC machining. The rivets must be precisely made to fit the specific application, meet strength and durability needs, and work effectively in automated production. This article will discuss how to find and select top quality rivets optimized for CNC machining operations.
CNC Compatibility
The first requirement for rivets used in CNC machining is compatibility with automated equipment. CNC machines rely on consistency and uniformity to function properly. The rivets must have incredibly precise dimensions and consistencies from rivet to rivet. Even slight variations in the diameter of the rivet body or shaft length can disrupt machine handling and indexing.
Rivets optimized for CNC use are manufactured to exacting tolerances using high precision processes and equipment. This ensures each rivet matches the specified measurements down to mere microns. Feeding and seating of the rivets in the CNC machine can then proceed smoothly without jamming or misfeeding issues.
Rivet heads must also have a uniform shape and size. Variations in rivet head shape or underfilled head cavities can cause problems with automatic feeding systems on CNC machines. Again, consistency is critical for seamless CNC production.
Material Strength
The strength of the rivet shaft and head is another chief consideration for CNC machining. Rivets supplied for CNC equipment must tightly match the strength specifications of the application.
CNC production often utilizes harder and stronger materials like steel, aluminum alloys, and high-tech composites. The rivets used in these applications are typically high strength as well to accommodate the material demands. Hardness levels between 40-55 HRC ensure the rivet can withstand high shear and tensile stresses from automated installation and during product use.
Aluminum and steel are common CNC rivet materials selected for high strength properties. Stainless steel provides excellent corrosion resistance in demanding environments. Copper and brass rivets offer electrical and thermal conductivity. Nickel alloy rivets provide a balance of strength, ductility, and chemical resistance. The choice of rivet material should align with the base material being joined and the performance requirements of the end product.
Driving Force Requirements
The force required to set and clamp the rivet must also be considered for CNC machinery. Setting force is applied by the rivet gun on the CNC system and must fully form the rivet head. Low driving force rivets optimize performance in high speed CNC production where rivets are set rapidly one after another.
However, sufficient clamping force must still be generated to create a tight joint. Rivet styles like blind rivets are designed to provide strong clamping force with lower set force for improved CNC operation. The rivet supplier can recommend compatible rivet designs that balance driving force and clamping force for automated environments.
Application Dimensions
Rivet dimensions need careful selection based on the materials being joined and the specific joint application. Shank diameter, head height, head diameter, grip range, and overall length should match the joint thickness and design.
Providers specialized in CNC rivets offer extensive selection charts covering hundreds of rivet dimensions and styles suited for common automated machining applications. Whether joining sheet metal, securing brackets, assembling frames, or other uses, the right CNC rivet specifications help achieve a strong assembled product. Custom sizing is also available for unique CNC applications if needed.
Reliable Feeding
Another key function required of rivets in CNC equipment is reliable feeding from bulk containers or pre-assembled sticks. Feeding systems on CNC machines index each new rivet into place rapidly. The rivets must flow smoothly without jamming, sticking, or misaligning.
Proper finish and control of details like flange and breakneck geometries promote trouble-free feeding. Vibratory bowls, escapements, and feed tracks on CNC machines are designed to work optimally with properly sized and finished rivets. Consultation with the rivet manufacturer helps identify suitable rivet configurations and finishes for each feeding method.
Speed of Production
One of the core advantages of using CNC machining is speed of production. CNC systems can install hundreds of rivets per hour compared to manual assembly. This productivity gain relies on super-fast rivet setting cycles of around one to two seconds.
Rivets made for CNC usage have properties enabling rapid setting. As mentioned above, factors like low set force, consistency, and feeding reliability allow the rapid setting pace demanded in automated production. CNC-grade blind rivets, for example, have specialized designs like break mandrels to facilitate high-speed setting.
Quality Certification
Reputable manufacturers providing rivets for CNC applications will have quality management certifications demonstrating their capabilities and process control. Certifications like ISO 9001 confirm the supplier follows standardized protocols for producing consistent and high quality rivets. The certifications provide assurance that each batch of rivets will meet specifications.
Additional CNC rivet testing like automated vision inspection and CMM measurement audits can also be implemented. Close monitoring and statistical control gives visibility to rivet quality and quickly identifies any issues for correction. This rigorous approach ensures that rivets flowing into CNC machines are within specifications for smooth automated production.
In Summary
There are many important factors that come into play when selecting quality rivets for CNC machining applications. Dialing in all the critical details of material, dimensions, drive requirements, and consistency ultimately allows CNC automation to run at maximum efficiency. Partnering with an experienced CNC rivet provider is the best way to access top quality rivets purpose-built for automated production success. Their expertise in specialty CNC rivets can improve end product quality, streamline production, and boost profitability for manufacturers utilizing CNC machining. CNC Milling
