Brass Copper CNC Machining Material Selection

In terms of material selection, we strictly screen brass and copper materials according to the needs of different application scenarios. For the electrical and electronic industry, we commonly use copper (T2, T3) and brass (H62, H65). Copper, with its extremely high purity and conductivity, is suitable for components such as wires and cables, transformer windings, etc. that require strict conductivity; H62 brass is widely used in electronic connectors, terminals, and other products due to its excellent comprehensive performance. In the field of hardware and bathroom, H59 brass has become the preferred material for faucets, valves, and other products due to its high strength and cost-effectiveness; In the manufacturing of musical instruments, brass alloys with special compositions can produce unique timbres. We will customize the selection of materials according to the type of instrument to ensure sound quality performance. All materials are purchased from high-quality suppliers and undergo strict chemical composition analysis and mechanical property testing to ensure that the material quality meets high standards.

Brass Copper CNC Machining Production Process

Our brass and copper CNC machining has a rigorous and efficient production process. Firstly, the technical team utilizes professional CAD/CAM software for process planning and programming based on the design drawings and technical requirements provided by the customer, accurately setting parameters such as tool path, cutting speed, and feed rate. Next, the brass and copper raw materials are fixed on high-precision CNC machining equipment, and various processing methods such as turning, milling, drilling, and boring are used to gradually remove excess materials and shape the parts. During the processing, the real-time monitoring system will monitor the operating status of the equipment and the machining accuracy of the parts. Once parameter deviations or abnormalities are detected, adjustments will be made immediately. After the processing is completed, the parts enter the initial inspection stage, and technicians use tools such as calipers and micrometers to conduct preliminary dimensional measurements. After passing the inspection, they enter the subsequent deep quality inspection process.

Brass Copper CNC Machining Surface Treatment

To improve the performance and appearance quality of brass and copper parts, we offer a variety of surface treatment solutions. Electroplating is one of the common processing methods, which can enhance the wear resistance, corrosion resistance, and decorative properties of parts through processes such as nickel plating, chromium plating, and gold plating. For example, nickel plating on electronic connectors can improve contact reliability, while chrome plating on bathroom products makes the surface brighter and more beautiful; Chemical plating forms a uniform coating on the surface of parts without relying on an external power source, making it suitable for parts with complex shapes. In addition, we also provide polishing treatment, which achieves a mirror effect on the surface of brass copper parts through mechanical polishing or electrolytic polishing, commonly used in handicrafts and high-end decorative parts; Passivation treatment can form a passivation film on the surface of the part, further improving corrosion resistance and extending the service life of the part.

Brass Copper CNC Machining Dimensional Inspection

We have established a strict and comprehensive dimensional inspection system to ensure high precision of brass copper CNC machined parts. Using a coordinate measuring instrument to measure parts in all directions can accurately obtain three-dimensional dimensional data of the parts, and perform micrometer level accuracy testing on parameters such as length, width, height, aperture, and angle; For some small precision parts or complex curved structures, optical imaging measuring instruments play an important role. Through non-contact measurement methods, they avoid damaging the surface of the parts and quickly and accurately obtain dimensional information. During the production process of each batch of parts, we conduct full first article inspection, process sampling inspection, and finished product inspection. We use statistical process control (SPC) methods to analyze the inspection data, timely discover and correct deviations in the production process, and ensure stable and reliable product quality.

Application of Brass Copper CNC Machining Products

Our brass copper CNC machining products are widely used in multiple fields. In the electrical and electronic industry, it is used to manufacture key components such as wires and cables, connectors, relays, switches, etc., to ensure stable transmission of power and signals; In the field of hardware bathroom, faucets, showerheads, fittings, door locks and other products have become the mainstream choice in the market due to the corrosion resistance and aesthetics of brass and copper; In terms of instrument manufacturing, brass instruments such as trumpet, trombone, and horn, as well as some copper percussion instruments, can display beautiful timbre and good playing feel through our precise processing technology; In addition, brass and copper parts also play an important role in handicraft production, clock manufacturing, mechanical transmission and other fields, meeting the strict requirements of different industries for product functionality and quality.
