The rolling machines are categorized into several models: two-axis eccentric, two-axis rolling through, two-axis hydraulic, two-axis hydraulic rolling through, three-axis cam, three-axis hydraulic, and three-axis hydraulic rolling through. During the threading process, rolling dies are installed on the rotating shafts of both two-axis and three-axis machines to extrude the thread shape, and different rolling dies of various specifications are used to produce different thread types.

Gear Hobbing Machine Advantages: Ensures product size stability and high precision, suitable for mass production of precision screws, available in fixed and roller-through styles. The fixed type can be equipped with a vibration dish within size constraints, achieving full automation. The roller-through style is ideal for long workpieces. The three-axis machine is primarily designed for machining hollow tube threads, tailored for pipe components. It employs isosceles triangular support to determine the true roundness of the workpiece, ensuring high precision, concentricity, and perpendicularity, making it an essential choice in the fastener industry.
