1.Introduction for Z28-500 thread rolling machine:

Thread 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

Automatic thread rolling machine is mainly used for radial cold roll forming, cold rolling process is an advanced non-chip processing technology, the process uses rolling tool extrusion, rolling metal fibers are continuous, rolling generated when pressure should be able to effectively improve the surface roughness, hardness and strength of the workpiece, improve work efficiency than cutting times, even a few times, it can save the material easier to automate processing.Rebar thread rolling machine

Screw thread rolling machine Rolling dies as rolling tool, special strong, suitable for rolling of the workpiece material is not higher than the hardness of HRC37, preferably HRC25 or less, the elongation should be greater than 10%, the tensile strength should be less than 100Kgf/mm (square) various carbon steel, alloy steel and non-ferrous metals, with the improvement of the material hardness of the rolling tool life dramatically

3.Characters for Z28-500 thread rolling machine:

3.1 High Efficiency and Energy Saving: Utilizing the cold rolling process, no chips are produced, resulting in high material utilization rate and low energy consumption.

3.2 Enhancing Component Performance: The radial compressive stress and cold work hardening effect generated during the processing process significantly enhance the fatigue strength, torsional strength and wear resistance of the component.

3.3 High Precision and Consistency: The thread profile is full and plump, the diameter consistency is good, and the surface roughness can reach ‌Ry 0.1–0.8 μm‌, with a precision level of ‌GB197-63 Grade 2‌.

3.4 Wide Applicability: Capable of processing workpieces with diameters ranging from ‌Φ4.2 to ‌Φ120 mm‌ (depending on the model); the pitch range is typically ‌0.3–8.0 mm‌; suitable for materials such as carbon steel, alloy steel, and non-ferrous metals (elongation > 10%, tensile strength < 1000 N/mm²)

3.5 Multi-mode Operation: Supports three working modes: manual, semi-automatic, and automatic. Some models are equipped with PLC control, human-machine interface, automatic feeding, and other functions.

3.6 Strong structural rigidity: Mostly uses cast steel bodies or high-strength welded structures to ensure processing stability

3.7 Environmental Safety: No open flames, no cutting fluid contamination (using water-soluble coolant), in compliance with national construction industry safety standards
