Detailed Explanation of Core Equipment for Knurled Screw Manufacturing: Precision Enables High-Quality Anti-Slip Fasteners

Knurled screws, as core anti-slip fasteners in mechanical assembly, electronic equipment, and instrumentation, achieve convenient manual tightening and secure locking through surface-knurled patterns such as straight lines and mesh patterns. Their processing precision, pattern regularity, and mechanical properties rely entirely on the precise operation of specialized manufacturing equipment. The manufacturing of knurled screws involves multiple processes, including knurling and precision finishing, each corresponding to dedicated core equipment.

I. Core Knurling Equipment: Creating Anti-Slip Patterns, Highlighting Core Product Value

Knurling is the core process for knurled screws. Specialized equipment uses a cold rolling process to extrude regular patterns onto the screw surface, ensuring clear and uniform patterns without damaging the screw's performance. This is a key piece of equipment in manufacturing.

- Knurling Machine (Thread Rolling Machine): Available in two-axis, three-axis, and fully automatic hydraulic types. It uses knurling wheels to plastically deform the screw surface, forming patterns. The two-axis thread rolling machine is a general-purpose type, suitable for Φ6~Φ80mm screws, and can switch between three operating modes with rolling pressures of 6~20T. The three-axis thread rolling machine is suitable for hollow and thin-walled screws, preventing deformation. The fully automatic hydraulic type improves efficiency by more than 50% and can simultaneously complete threading and knurling. Its core function is to ensure regular patterns, free of irregularities and defects, ensuring coaxiality, and improving anti-slip properties and aesthetics.

- Lathe (including knurling cutter): Used for high-precision, small-batch, and irregular-shaped knurled screw processing. The blank is fixed on the chuck, and the pattern is formed by extrusion through the knurling cutter. Pattern parameters can be precisely controlled. The knurling cutter can be replaced as needed, providing high processing accuracy and suitable for screws used in precision instruments, overcoming the customization limitations of thread rolling machines.

II. Finishing and Inspection Equipment: Strict quality control ensures compliant delivery.

After knurling, finishing and optimization details are required, followed by inspection to check for defects, ensuring that the product meets specifications, guarantees interchangeability, anti-slip properties, and service life, and conforms to industry standards and customer needs.

- CNC Lathes: Perform precision finishing on knurled screws, including precision turning of the shank and chamfering of the head, controlling dimensional tolerances to ≤±0.01mm, removing burrs and flash, ensuring a smooth surface, precise dimensions, and optimized appearance.

- Heat Treatment Equipment: Improve the mechanical properties of the screws, eliminate machining stress, enhance hardness, wear resistance, and fatigue resistance, preventing deformation and breakage during use. High-strength screws can have their surface hardness further improved through carburizing and tempering processes, making them suitable for heavy-duty applications.

- Precision Testing Equipment: Includes projectors, hardness testers, thread gauges, etc., for comprehensive product quality testing. Projectors detect pattern parameters, hardness testers test mechanical properties, thread gauges test thread accuracy, and surface defects are identified, ensuring a 100% pass rate.
