In the electrical parts and automation equipment manufacturing industry, high-precision and high-stability metal machined parts are key components that ensure the performance and longevity of the entire machine. We are a professional metal parts processing factory based in China, primarily specializing in the production of electrical metal parts and automated assembly equipment. We have independent research and development and manufacturing capabilities, are equipped with mature CNC processing workshops, and can provide overall solutions from drawing design, and CNC machining metal parts processing, to integrated assembly delivery.
Characteristics and adaptation fields of main processing materials
We have long-term reserves and batch use of raw materials such as red copper, brass, aluminum alloy, stainless steel, etc. Combined with many years of CNC machined metal parts processing experience, we can formulate optimal processing parameters for different material characteristics to achieve a balance between product performance and cost.
1. Copper machined parts (T2, TU1, etc.)
Material properties: Copper has extremely high electrical and thermal conductivity, good plasticity, and strong ductility. The copper CNC milling process causes great wear on the tool, requiring the machining tool to be sharp and fully cooled.
Application areas: Used for high-current conducting components, electrical contacts, wiring terminals, busbar connectors, etc.
Machining points:
Accurately control the feed speed to avoid surface roughening;
Strengthen the cooling system to prevent heat and oxidation during machining;
Can realize complex three-dimensional structure machining, such as inner cavity conductive channels, step positioning structures, etc.
2. Brass machined parts (H59, H62, etc.)
Material properties: Brass has good cutting performance, moderate strength and corrosion resistance, is suitable for batch processing, and has a high surface finish.
Application areas: Used for small and medium-sized brass CNC machining parts such as switch slides, connecting nuts, rotating structural parts, and sealing structures.
Machining points:
High-speed cutting can improve batch efficiency;
The surface can achieve a high finish without secondary treatment;
Thread processing and chamfering are stable.
3. Aluminum alloy machined parts (6061-T6, 5052, 7075, etc.)
Material properties: Aluminum alloy is light, corrosion-resistant, and has good thermal conductivity. It is suitable for high-speed processing of complex shapes and is suitable for use in automation equipment and appearance aluminum CNC turning parts.
Applicable fields: Applicable to robot joints, equipment mounting bases, battery module brackets, etc.
Machining points:
The key to tool sharpness control is to prevent the material from sticking to the knife;
Can perform various surface treatments such as anodizing and sandblasting;
CNC engraving has high precision and can process 0.02mm-level micro features.
4. Stainless steel machined parts (304, 316, 303, 420, etc.)
Material properties: Stainless steel has high strength, high hardness, strong corrosion resistance, high processing difficulty, and high requirements for equipment stability.
Application areas: Used in high-durability occasions such as structural support parts, guide rail positioning CNC stainless steel parts, and medical device parts.
Machining points:
High-rigidity tools and high-torque spindles are required during processing;
Chip removal efficiency must be guaranteed to prevent tool chipping;
Suitable for fine grinding, fine drilling, and precision surface grinding processes.
