Product Description High Strength Alloy Knurl Shaft - CNC Precision Ground & OEM Knurling is a mechanical process that creates a pattern or tooth pattern on the shaft surface through a rolling process. It is often used to enhance grip or aesthetics. The process includes material selection, turning, knurling (using straight or mesh knurling tools), finishing, and quality inspection. It offers advantages such as high efficiency, wear resistance, and anti-slip properties, making it widely used in the manufacture of tools, hardware, and transmission components.

Their surface knurling enhances friction and ensures stable transmission. The manufacturing process involves advanced processes such as CNC precision turning, 5-axis machining, and surface electroplating to ensure high precision and durability.Core Processing Techniques for Knurled Shafts1. CNC Precision Turning Knurled shaft blanks are typically machined from high-quality die steel (such as SKD11) or brass (H59). First, they are precision turned on a CNC lathe to ensure the shaft's cylindricity (≤0.01mm) and dimensional tolerance (±0.02mm). During the turning process, cutting parameters (such as a speed of 800-1200rpm and a feed rate of 0.1mm/r) must be strictly controlled to prevent material deformation and burrs.2. 5-Axis CNC Precision Knurling Traditionally, knurling is performed by extrusion, but high-precision knurled shafts require precision milling or engraving using a 5-axis CNC machine to ensure uniformity and depth consistency of the pattern (straight, crosshatch, or diagonal) (typically 0.2-0.5mm). 5-axis machining can produce complex knurling structures in a single pass, eliminating secondary clamping errors and making it particularly suitable for knurled shafts with special shapes or keyways.3. Heat Treatment and Surface Hardening For high-load transmission knurled shafts, a tempering heat treatment (quenching and tempering) is required to achieve a hardness of HRC 45-50 and improve wear resistance. Some precision shafts also undergo nitriding, creating a 0.1-0.3mm hardened layer on the surface to extend service life.4. Surface PlatingFor enhanced rust resistance and aesthetics, knurled shafts are typically nickel-plated or chrome-plated.Nickel plating: Improves corrosion resistance and is suitable for precision shafts used in electronic equipment.Hard chrome plating: Surface hardness can reach HV900, suitable for high-wear environments, such as drive shafts in automated assembly machines.Applications of knurled shaftsElectronic equipment: Used in feed rollers and tension adjustment shafts in SMD placement machines, ensuring precise transmission.Mechanical transmission: Used as drive shafts in handles and knobs, enhancing grip friction.Automated equipment: Provides stable torque transmission in robot joints and conveyor belt adjustment mechanisms.Industry trendsCombined machining technology: Combining 3D printing and 5-axis CNC enables the manufacture of lightweight, custom-shaped knurled shafts.Intelligent inspection: Uses machine vision to automatically inspect knurl pattern quality, improving yield.Environmentally friendly surface treatment: New processes such as cyanide-free electroplating and PVD coating meet RoHS environmental requirements.
