Cnc Joint Double Outer Cone Lathe

CNC double external taper lathe for joints is a specialized equipment for the external taper machining of electrode joints and other workpieces, which is often applied to graphite electrode joints processing in carbon and other industries. Taking this kind of machine tool involved in the relevant technical data as an example, its features and functions are as follows:

Processing object and adaptable range

It is mainly used for processing joints with specific specifications, such as double taper turning for joints with diameters of Φ120 – Φ431mm and lengths of 177 – 635mm, which is suitable for the processing of graphite electrode joints and other parts requiring taper accuracy in industrial production, to meet the dimensional requirements of the carbon industry and other industries for the processing of electrode joints, and to provide accurate taper matching structures for subsequent electrode assembly and other links.

Processing accuracy guarantee

Pulse equivalent: usually with high control accuracy, like some machine tools, the pulse equivalent can reach 0.001mm, which enables the CNC system to accurately control the tool trajectory to ensure the dimensional and shape accuracy of the outer taper machining, so that the outer taper of the turning surface is accurate, smooth surface, to meet the demand for precision fit.

Shape and position tolerance control: the shape and position tolerance such as length error (e.g. within 0.1mm) can be strictly controlled to ensure the precision of the double outer taper surface of the joints in the length direction after machining, so as to ensure the consistency and stability of the joints when assembled with other parts and improve the overall product quality.

Structure and workflow

Structural composition: it generally contains spindle parts, tailstock parts, turning mechanism and dust-absorbing device. The spindle part drives the workpiece to rotate, and the tailstock part is used to tighten the workpiece to ensure the stability of the workpiece during the processing; the turning mechanism is responsible for the external taper turning processing of the workpiece, which is driven by servo motor to realize the accurate tool walking; the dust-absorbing device can clean up the dust generated in the processing in a timely manner (e.g., the graphite dust during the graphite processing) to protect the equipment and the processing environment.

Workflow: after the workpiece is sent from the truss conveyor line, make sure the center of the workpiece coincides with the center of the spindle, the center hole of the workpiece and the top of the spindle fit as much as possible, the spindle of the tailstock will tighten the workpiece under the action of the cylinder, the manipulator will loosen the workpiece and return to the safe position, and the protective door will be closed.

After processing is completed, the spindle stops rotating, the guard door opens, the manipulator grabs the workpiece, the tailstock spindle backs up, and the manipulator moves the workpiece to the next workstation to realize automation and continuous processing.

power and performance

Parameters such as the main motor power affect the machining capacity, such as the main motor power of the machine tool is 7.5kw, which can provide enough power to drive the spindle rotation and tool holder movement, to cope with the demand for turning of joint materials (such as graphite, metal, etc.);

the spindle speed is generally set reasonably (e.g., 230rpm), which can guarantee the machining efficiency and maintain the smoothness of machining process to avoid problems such as reduced precision and tool wear due to inappropriate rotational speed.

The spindle speed is usually set reasonably (e.g. 230rpm) to ensure the machining efficiency and maintain the smoothness of the machining process, avoiding the problems such as the decline of machining accuracy and the rapid wear of the tool due to improper speed, and helping to realize the highly efficient and stable double taper processing.

This kind of machine tool occupies an important position in the electrode production line of carbon and other industries. By accurately machining the double taper surface of the joint, it ensures the overall assembly accuracy and performance of the electrode, and promotes the development of precision manufacturing in the related industries.
