Threading is the process of creating screw threads, which are essential components in various mechanical systems. There are several methods to generate threads, each with its own advantages and applications. The choice of method depends on factors such as precision, production volume, material properties, and available equipment.

Subtractive Methods

Thread Cutting

Thread cutting involves removing material to create threads. This method is suitable for small quantities, brittle materials, or when full thread depth is required. Common tools for thread cutting include taps and dies, which can create internal and external threads, respectively.

Single-Point Threading

Single-point threading uses a single-point tool to produce threads on a cylinder or cone. This method is often used for custom or unique threads and requires precise coordination of machine elements. CNC lathes are commonly used for single-point threading due to their ability to track tool and spindle positions accurately.
