　　A three-axis thread-rolling machine is a versatile cold-extrusion forming machine tool that, within its rolling force range, can perform thread rolling, straight‑thread rolling, and helical‑thread rolling on workpieces in the cold state. The following is a detailed introduction to the three-axis thread-rolling machine:

　　Processing Capability: The three-axis thread-rolling machine can easily produce a variety of tubular threads and is also suitable for knurling, mesh‑pattern rolling, straight‑line rolling, and other operations. It employs an equilateral‑triangle support system to ensure excellent roundness and perpendicularity, facilitating easy inspection with go and no‑go gauges.

　　Equipment Features:

　　Specifically designed for tubular threads, it is suitable for thin-walled tubes with a wall thickness of 1.5 mm or greater and can produce rolled threads, knurled patterns, straight grooves, and more.

　　It employs hydraulic drive, offering smooth operation, variable speed control, and stable performance.

　　Compact in design, with a rigid cast-steel body and a simple structure; the oil tank is integrated, minimizing space requirements and facilitating easy maintenance and repair.

　　An automatic feeding device can be added to enable automated production.

　　Inverter-driven power, with infinitely adjustable spindle speed, PLC-programmed control, and a user-friendly HMI for effortless operation.

　　Processing advantages: Thread rolling is a plastic‑deformation process, unlike cutting processes such as those performed on automatic lathes, and produces no metal chips. The thread surface after rolling exhibits increased strength and hardness due to work hardening. Surface roughness is lower than that achieved by turning, milling, or grinding. Products obtained through this method offer superior perpendicularity, concentricity, and overall dimensional accuracy compared with those produced on two‑axis thread‑rolling machines. Material utilization is high, productivity is several times greater than that of cutting operations, and automation is readily achievable. Moreover, thread‑rolling dies have an exceptionally long service life.

　　Precautions for Use:

　　The cooling fluid used in thread‑rolling machines must be a water‑soluble emulsion; oil‑based coolants are strictly prohibited, and ordinary lubricating oils must never be used as substitutes.

　　The reducer should be lubricated regularly to maintain the specified oil level.

　　The slide and slider should be cleaned and lubricated regularly.

　　During initial cutting, feed should be uniform; avoid abrupt advances to prevent chipping or breakage of the cutting edge.

　　Thread-rolling machines should be regularly maintained, and the thread-rolling dies and rib‑stripping cutters must also be inspected and serviced on a routine basis.

　　In summary, the three‑axis thread‑rolling machine is an energy‑efficient, low‑consumption ideal process equipment, widely used for thread‑rolling operations on oil‑pipe fittings, automotive and bicycle components, air‑conditioner evaporator tubes, various fasteners, condenser copper tubes, and other workpieces.
