Copper alloys are preferred in various electrical applications, including bus bars and wire connectors, due to their excellent electrical and thermal conductivity. The high purity of 101 copper ensures superior conductivity, while 110 copper is generally more cost-effective as it is easier to CNC machine. Copper beryllium (CuBe) offers a unique combination of high strength, non-magnetic properties, and non-sparking qualities, making it an excellent choice for CNC machining, forming, and general metalworking.
Copper has good thermal conductivity, electrical conductivity, and ductility. It also exhibits good corrosion resistance and weldability, making it widely used in machining processes.
When machining steel, consider factors such as the type of steel, its hardness, and the desired finish. Proper tool selection, cutting speeds, and lubrication are crucial to achieving precise results and prolonging tool life. It’s also important to manage heat generation to prevent warping or damaging the workpiece.
The carbon content significantly impacts steel’s hardness, strength, and ductility. Higher carbon content typically increases hardness and strength but reduces ductility. Lower carbon content results in softer, more ductile steel that is easier to machine and weld.
Steel offers high strength, durability, and excellent machinability. It can be precisely cut, shaped, and drilled, making it ideal for producing complex and high-precision parts. Additionally, steel’s versatility allows it to be used in a variety of applications, from automotive components to industrial machinery.
CNC mill-turn refers to a type of computer numerical control (CNC) machine that combines milling and turning operations in a single setup. This hybrid machine allows for both rotating the workpiece (turning) and rotating the cutting tools (milling), providing greater flexibility and efficiency in manufacturing complex parts.
Bead blasting post-processing involves using a bead blasting machine to propel spherical beads (such as glass, plastic, or ceramic) at high speed onto the surface of an object. This process cleans, polishes, or textures the surface, creating a smooth and uniform finish. After bead blasting, the object may require further treatment, such as cleaning, corrosion protection, or additional surface finishing, to achieve the desired results.
After bead blasting, surfaces can become contaminated. Wearing clean gloves when handling the parts is recommended. Surface cleaning methods include washing with water, solvent cleaning, and air blowing. The specific method depends on the material of the object and the type of beads used during blasting.
To ensure an even bead blasting effect on complex-shaped parts, adjust the angle, direction, and pressure of the blast gun, or use special fixtures and turntables. This helps to reach all surfaces uniformly and achieve consistent results.
After bead blasting, metal surfaces are prone to oxidation. Applying corrosion protection treatments, such as anti-corrosion coatings or plating, can help prevent rust. It’s important to perform these treatments promptly after blasting to avoid oxidation.
To further improve the appearance, consider additional surface treatments such as polishing, grinding, or applying coatings. These steps can help achieve a smoother, shinier surface and enhance the visual quality of the material.
Controlling surface roughness after bead blasting involves adjusting the type and size of the beads, the blasting pressure and distance, and the duration of the process. Using finer beads, lower pressure, and maintaining a consistent distance can help achieve a smoother finish.
