Thread rolling machine
A Thread Rolling Machine is a specialized metal forming machine tool that uses cold forming technology to produce threads, splines, knurls, and other profiles on cylindrical workpieces. Unlike thread cutting or grinding methods that remove material, thread rolling displaces the material by applying high pressure between rotating dies, forming the thread profile through plastic deformation.
This cold working process preserves the material's grain structure, resulting in threads with superior strength, excellent surface finish, and enhanced fatigue resistance—making rolling the preferred method for high-quality threaded components.
ZC28-12.5 thread rolling machineThread rolling machines are primarily used for rolling various types of precision external threads, high-strength standard parts, anchor bolts, T-screws, and other workpieces with larger thread pitches.
Automatic thread rolling machines are mainly employed for radial cold roll forming. This cold rolling process represents an advanced non-chip processing technology. The process utilizes rolling tools for extrusion, ensuring continuous metal fibers. The pressure generated during rolling effectively improves surface roughness, hardness, and strength of the workpiece. Compared with cutting processes, thread rolling improves work efficiency by several times or even more, while also saving material and facilitating automated processing.
Z28-150 thread rolling machineThe Z28-150 is a compact, two-die cylindrical thread rolling machine designed for cold-forming precision external threads on small to medium-sized workpieces. It is widely used in hardware manufacturing, standard parts production, automotive components, and construction fastener fabrication.- Z28-250 thread rolling machineThe Z28-250 is a two-die cylindrical thread rolling machine designed for cold-forming precision external threads, high-strength standard fasteners, T-shaped screws, anchor bolts, and workpieces requiring larger thread pitches. It is widely used in hardware construction, automotive and motorcycle parts manufacturing, traffic power equipment, and standard parts production.
- Z28-500 thread rolling machineThe Automatic Thread Rolling Machine utilizes radial cold roll forming—an advanced non-chip (chipless) machining process. The rolling tool extrudes the material, creating continuous metal fibers without cutting. The compressive pressure generated during rolling effectively improves surface roughness, hardness, and strength of the workpiece. Compared to thread cutting, rolling increases production efficiency by several times (even dozens of times), saves material, and facilitates automated processing.
- Z28-650 thread rolling machineThread rolling machine is mainly used for rolling various types of precision external thread, high-strength standard parts and anchor bolts and T-shaped screws and other workpieces with larger screw pitch.
- Z28-1000 thread rolling machineThread rolling machine is mainly used for rolling various types of precision external thread, high-strength standard parts and anchor bolts and T-shaped screws and other workpieces with larger screw pitch.
