As a core component in the manufacture and assembly of machine tools, precision machine tool screws assume a variety of functions such as connection, fixation, transmission and positioning. Their precision, strength and durability are directly related to the overall performance and operational stability of machine tools. Therefore, customized precision machine screws are particularly important to meet the specific needs of different machine tools.
1. Precision machine screw production process
Material selection and pretreatment: According to the use of screws and performance requirements, selected high-strength, corrosion-resistant, wear-resistant alloy steel, stainless steel or titanium alloy and other materials. Materials need to undergo rigorous testing and pretreatment, such as pickling, phosphating, etc., in order to improve its surface quality and processing performance.
Precision design and manufacture of molds: According to the specifications, shape and accuracy requirements of the screw, precision design and manufacture of the corresponding injection or stamping molds. The precision and durability of the mold is directly related to the screw molding quality and production efficiency.
Molding and heat treatment: The material is processed into the initial shape of the screw by means of precision injection molding, stamping or machining. Subsequently, heat treatment, such as quenching, tempering, etc., to improve the hardness, strength and toughness of the screw.
Precision machining and inspection: The preliminary shaped screws are subjected to precision machining, such as turning, milling, grinding, etc., in order to achieve the required accuracy and surface quality. At the same time, strict size measurement, performance test and appearance inspection are carried out to ensure that the quality of screws meets customer requirements and industry standards.
Surface treatment and packaging: The screws are subjected to surface treatment, such as zinc plating, blackening, plastic spraying, etc., in order to improve their corrosion resistance and aesthetics. Finally, packaging and labeling for storage, transportation and subsequent use.
2. Customization of precision machine screws
Specification customization: according to the specific needs of customers, provide a variety of specifications of screw customization services, including length, diameter, pitch, etc..
Shape customization: According to the special requirements of the machine tool, provide special shape screw customization services, such as hexagon head, hexagon head, flat head and so on.
Performance customization: According to the working environment of the machine tool, provide screws with different performance customization services, such as high-strength, corrosion resistance, wear resistance and so on.
Surface treatment customization: provide a variety of surface treatment customization services to meet the customer’s requirements on the appearance and corrosion resistance of screws.
Batch customization: according to the customer’s order quantity and delivery requirements, to provide efficient mass production services to ensure on-time delivery of high-quality screws.
3. Introduction of materials for precision machine screws
