Rivets are an integral component in many manufacturing and construction projects. While rivets may seem simple, using high quality rivets suited for your specific application is crucial for safety, durability, and performance. For CNC machinery, specialized rivets are required to withstand the high speeds, vibrations, and forces exerted during CNC operations. This article will examine the characteristics of quality rivets for CNC applications and how they are manufactured.
Desired Properties of CNC Rivets
Strength and Toughness
Rivets used in CNC equipment need to be very strong to avoid shear or deformation under load. Strong rivet materials like steel alloys are preferred over softer options like aluminum. The rivets also need impact and fatigue resistance to endure ongoing vibrational forces.
Precision Dimensions
CNC rivets must be manufactured to precise diameters, lengths, and head dimensions. This level of consistency allows for accurate automated riveting during CNC programming and operation. Any dimensional deviations can throw off hole alignments.
Corrosion Resistance
CNC machines operate under high heat, pressures, and friction. Rivets need corrosion resistance coatings to avoid degradation over time under these conditions. Nickel coatings are a popular anti-corrosive solution for steel rivets used in CNC applications.
Non-Magnetic Properties
Given all of the sensitive electronics and proximity of magnets in CNC equipment, it is crucial that rivets be non-magnetic to avoid electromagnetic interference. Non-magnetic stainless steel and brass alloys are common choices.
High Clamping Force
The rivets used in CNC assemblies must provide strong clamping force to hold parts tightly together during high G-forces. Large head rivets and interference fit rivets are good choices for maximizing clamp load.
How Quality Rivets Are Manufactured
Raw Materials
It all starts with high grade raw materials that meet the desired properties above. Aircraft quality steel alloys are commonly used. The metals are closely examined for internal defects before being approved.
Precision Cutting
The raw steel rods are fed into cutting machines where they are trimmed to high precision lengths within .001 inches. Mechanical or hydraulic cutting provides a clean cut edge.
Headed rivets require formation of the rivet head. This is accomplished through cold forging where the rivet tip is smashed between dies to flare out the rivet head. The force and die geometry are carefully controlled to create uniform head dimensions.
If an anti-corrosive coating is needed, the rivets will be coated via electroplating. The nickel coating applied helps resist corrosion for offshore, marine, or high moisture applications.
Heat Treating
To maximize rivet strength, heat treating processes like quenching and tempering may be used. This involves heating the rivets up in a furnace and then rapidly cooling to make the steel harder and stronger.
Final Quality Control Check
The finished rivets will go through final inspections to verify correct dimensions, head style, surface defects, and materials. Testing may also be done on sample rivets for tensile strength, hardness, and metallurgy.
Proper Rivet Selection
With so many size and material options, selecting the right CNC rivets for your application requires some consideration:
- Determine the shear and tensile strength needed to securely join parts. This determines the required diameter and material.
- Consider the spacing between holes and proximity to edges to pick an appropriate rivet length.
- Pick a rivet head shape (round, countersunk, flat etc) suited for your assembly method and hardware.
- For sensitive electronics, make sure rivets are non-magnetic.
- Choose coatings like nickel if environmental resistance is needed.
By taking these factors into account, you can select optimized rivets for your CNC machinery applications. Investing in high quality rivets helps ensure the safe, reliable, and consistent performance of your CNC equipment over the long run. Precision manufactured and inspected rivets serve as robust fasteners even under the high demands of CNC systems. With proper rivet selection and integration, your CNC machinery will benefit from secure and vibration resistant connections for years to come. CNC Milling CNC Machining
