What Causes Irregular Patterns During Lathe Knurling?

[BriellaLynn]

Possible reasons for irregular patterns during lathe knurling include fine iron filings or rust spots in the knurling tool's teeth, insufficient initial cutting pressure, or excessive contact area between the knurling tool and the workpiece surface. Below is relevant information about lathes: 1. Lathe Development: Ancient lathes relied on hand-pulling or foot pedals to rotate the workpiece via ropes while cutting with handheld tools. In 1797, British mechanical inventor Henry Maudslay created the modern lathe with a leadscrew-driven tool holder, and in 1800 introduced change gears to adjust feed rates and thread pitches. In 1817, another British engineer, Richard Roberts, implemented a four-step pulley and back-gear mechanism to alter spindle speeds. 2. Development Direction: The application of CNC technology has not only revolutionized traditional manufacturing, making it a symbol of industrialization, but also plays an increasingly vital role in key industries affecting national economy and livelihoods (IT, automotive, light industry, healthcare, etc.) as digitalization of required equipment becomes a major modern trend. Current CNC lathes exhibit the following development trends.
