As modern precision processing equipment, automatic lathes play a vital role in the production of valve stem parts with their high-precision and high-efficiency processing capabilities. Compared with traditional manual or semi-automatic lathes, automatic lathes have the following significant advantages:
High-precision processing: Automatic lathes use advanced control systems and precise transmission mechanisms to achieve micron-level processing of valve stem parts, ensuring that the dimensional accuracy, shape accuracy and position accuracy meet the design requirements. This high-precision processing capability provides a solid foundation for subsequent nickel plating and ensures the uniformity and density of the coating.
High-efficiency production: The automatic lathe realizes automated control of the processing process through preset program control. During the processing, the lathe can automatically complete cutting, feeding, retracting and other actions, greatly improving production efficiency. Because the automatic lathe has a high degree of repeatable positioning accuracy, it can ensure the consistency of the processing quality of the same batch of valve stem parts, reducing the scrap rate and production costs.
Strong adaptability: The automatic lathe can process valve stem parts of various shapes and sizes, with strong adaptability. By replacing the tool and fixture, the processing of valve stem parts of different specifications can be realized. In addition, the automatic lathe also supports a variety of processing methods, such as turning, milling, drilling, etc., which can meet the complex processing requirements of valve stem parts.

In the production process of valve stem parts, the processing process of the automatic lathe usually includes the following steps:
Drawing analysis and programming: According to the design drawings of the valve stem parts, process analysis and programming are carried out. The programmer needs to select appropriate processing parameters and tool paths according to the geometric shape, dimensional accuracy and surface quality requirements of the parts, and write the processing program.
Material preparation and clamping: Cut and pre-process the copper material according to the requirements of the design drawings to ensure that the quality and size of the material meet the processing requirements. Then, clamp the copper material on the fixture of the automatic lathe to ensure that the clamping is firm and the positioning is accurate.
Roughing and semi-finishing: In the roughing stage, the automatic lathe removes most of the copper material at a faster cutting speed and a larger feed rate to form the basic shape of the valve stem parts. In the semi-finishing stage, the lathe further processes the valve stem parts with a smaller cutting amount and feed rate to improve the dimensional accuracy and surface quality.
Finishing: In the finishing stage, the automatic lathe uses high-precision tools and cutting parameters to perform the final processing of the valve stem parts to ensure that the dimensional accuracy, shape accuracy and position accuracy meet the design requirements. The lathe also needs to perform finishing on the surface of the valve stem parts to improve the surface quality and adhesion of the nickel plating layer.
Quality inspection and packaging: After the processing is completed, the valve stem parts are quality inspected, including dimensional measurement, shape inspection, position verification, etc. After ensuring that all indicators meet the design requirements, they are cleaned, dried and packaged to prepare for subsequent nickel plating.

The high precision and high efficiency of automatic lathe processing provide high-quality substrates for subsequent nickel plating. High-quality substrates have the following significant advantages:
Improve the quality of the plating: Due to the high dimensional accuracy and good surface quality of the valve stem parts processed by the automatic lathe, the nickel plating layer can be evenly and densely attached to the surface of the substrate to form a solid protective barrier. This not only improves the corrosion resistance of the valve stem parts, but also enhances their wear resistance and hardness.
Reduce nickel plating costs: High-quality substrates can reduce the scrap rate and rework rate during the nickel plating process, reducing the cost of nickel plating. Due to the uniform and dense plating layer, the consumption and discharge of nickel plating liquid are reduced, which is beneficial to environmental protection and sustainable development.
Improve production efficiency: The high efficiency of automatic lathe processing shortens the processing cycle of valve stem parts and provides sufficient time for subsequent nickel plating. This is conducive to the continuous operation and batch production of the production line, and improves production efficiency.
