The CNC threading system with helical seat toolholder represents an advanced and precise solution for producing external metric threads on a wide range of materials and mechanical components.

The operating principle is based on the use of a toolholder equipped with spiral-shaped seats designed to hold profiled inserts according to the pitch of the thread to be machined.

Through proper CNC machine programming, the process is carried out by chip removal, ensuring controlled milling and the highest level of precision. The toolholder, available in different outer diameters, enables the creation of external threads in full compliance with the project or technical drawing, adapting perfectly to specific dimensional and geometric requirements.

Thanks to the special spiral arrangement of the inserts, the system guarantees smooth cutting and vibration-free threading, achieving a perfect and uniform thread on any material — steels, stainless steels, light alloys, cast irons, titanium, and non-ferrous materials. The inserts for external metric threading are universal and can be used on all materials, eliminating the need for dedicated tools and simplifying stock and tool management operations.

Applications of this technology cover all fields of precision engineering, including automotive, aerospace, space, oil & gas, industrial valves, safety systems, and machine tool manufacturing. Moreover, the system’s versatility makes it ideal for prototype production, single parts, or small batches, where accuracy and thread consistency are key requirements.

With the ability to produce customized threads that retain the standard metric profile but feature tailored diameters, this method ensures high production flexibility and perfect adaptability to every design requirement.

Choosing the right inserts and machining parameters is essential to maximize tool life and part quality.
