How to make Knurling on Hobbing | Knurling on S. S Shaft

Knurling shaft refers to a shaft with a knurled surface. Knurling is a process of creating small ridges or texture on a surface, typically on a metal shaft or handle, to provide a better grip or traction.

A knurling shaft typically has a series of small ridges or bumps that are evenly spaced along the length of the shaft. This texture provides several benefits, including:

1. Improved grip: The ridges provide a secure grip, making it easier to hold and rotate the shaft.
2. Reduced slipping: The texture helps prevent slipping and sliding, even in oily or wet conditions.
3. Increased friction: The ridges increase the friction between the shaft and the surrounding material, making it easier to transmit power or motion.

Knurling shafts are commonly used in various applications, including:

1. Power tools (e.g., drill bits, socket wrenches)
2. Machinery (e.g., gear shafts, axles)
3. Automotive (e.g., steering columns, shift levers)
4. Aerospace (e.g., control rods, actuator shafts)
5. Medical devices (e.g., surgical instruments, implantable devices)

The knurling process involves rolling or pressing the ridges onto the shaft surface, creating a durable and long-lasting texture.
