Rivets are a crucial component in many manufacturing and construction applications. While rivets may seem simple, producing consistent, high quality rivets requires precision machining. CNC (Computer Numerical Control) machining has become the dominant method for manufacturing rivets with tight tolerances and repeatable quality. In this article, we’ll look at how CNC technology enables rivet manufacturers to achieve high standards for straightness, head formation, surface finish, and dimensional accuracy.
The Basics of CNC machining:
CNC machining utilizes computer control to automate and precisely guide machine tools like lathes, mills, routers, grinders, and drills. In CNC machining, the desired part geometry is programmed into CAM (Computer Aided Manufacturing) software which then generates code to instruct the motions of the machine tool. This allows for accurate and repeatable machining with minimal human intervention once the program is verified.
CNC technology provides rivet manufacturers consistent control over the machining process variables including feed rate, spindle speed, depth of cut, and tool path. Parts can be machined 24/7 with precision and accuracy significantly beyond manual machining. Programmed tool paths andPARAMETERS ensure every rivet meets design specifications.
Maintaining Straightness and Alignment:
A primary quality concern for rivets is straightness of the shank. Rivets must be perfectly straight to fit through aligned holes and prevent buckling during installation. CNC lathes and mills holding precise tolerances on concentricity and perpendicularity can repeatedly produce rivet blanks with straight, aligned shanks.
CNC machines also enable the use of coordinated multi-axis movements. For example, a milling machine with a rotary axis can manipulate round rivet blanks to access all surfaces and machine features at refined angles all around the part. This facilitates optimally straight and aligned rivets. Precision CNC rotary tables further improve alignment during secondary milling operations on the rivet head.
Optimizing Head Geometries:
Forming the rivet head presents another quality challenge. The head must be precisely shaped to achieve a flush fit and solid clinching when installed. CNC machining offers rivet manufacturers flexibility in head geometries and control over shape intricacies.
CNC milling utilizes specialty cutters like ball end mills to cleanly form domed or rounded rivet heads. Programmed tool paths control the cutter shape and diameter to dial in the exact head curvature. Different head contours can be adjusted in the CNC program as needed.
Achieving high quality standards for critical components like rivets requires consistency and precision. Manual machining simply cannot offer the repeatability and tight tolerances possible with CNC technology. CNC machining digitally controls all aspects of the machining process giving rivet manufacturers complete command over machining parameters. This leads to optimized straightness, alignment, head formation, surface finish, and dimensional accuracy part after part. For quality-driven rivet production, CNC machining is an indispensable manufacturing solution. CNC Milling
