COOPER material in the context of CNC (Computer Numerical Control) machining typically refers to a class of copper-based materials. Copper is widely used in CNC machining due to its excellent electrical conductivity, thermal conductivity, corrosion resistance, and machinability. Here are some common types of copper materials used in CNC machining:
Pure Copper (C10100, C11000)
C10100 (Oxygen-Free Electronic Copper): This type of copper has high electrical conductivity and is often used in applications requiring excellent conductivity and low oxygen content.
C11000 (Electrolytic Tough Pitch Copper): This is the most common type of copper used in electrical applications. It offers good electrical conductivity and is used in electrical wiring and components.
Brass (Copper-Zinc Alloys)
C36000 (Free-Cutting Brass): Known for its excellent machinability, C36000 is commonly used in CNC machining for parts requiring intricate detailing. It's used in fittings, valve parts, and fasteners.
C38500 (Architectural Bronze): Often used in decorative applications, it provides a balance of machinability and corrosion resistance.
Bronze (Copper-Tin Alloys)
C93200 (Bearing Bronze): This material is used in applications requiring good wear resistance and low friction. It's often used in bushings and bearings.
C95400 (Aluminum Bronze): Known for its high strength and excellent corrosion resistance, this material is used in marine applications and heavy-duty components.
Copper-Nickel Alloys (Cu-Ni)
C71500 (70-30 Copper-Nickel): This alloy has excellent corrosion resistance, especially in marine environments. It's used in seawater piping, heat exchangers, and condenser tubes.
Beryllium Copper (CuBe)
C17200 (Alloy 25): Known for its high strength and hardness, as well as good electrical and thermal conductivity. It is used in applications requiring non-sparking tools, springs, and electrical connectors.
When machining copper and its alloys, there are several considerations to keep in mind:
Tooling: Use sharp cutting tools made from carbide or high-speed steel. Copper tends to be sticky, so appropriate tool coatings (such as TiN) can help reduce tool wear and improve surface finish.
Cutting Speed and Feed Rate: Copper alloys generally allow for higher cutting speeds, but the feed rates should be adjusted according to the specific alloy and the desired surface finish.
Coolant: Proper coolant application is crucial to prevent overheating and to achieve a good surface finish. Using a water-soluble coolant is common.
Chip Formation: Copper alloys can produce long, stringy chips. Chip breakers or peck drilling techniques can help manage chip formation and evacuation.
Workholding: Ensure the workpiece is securely held to avoid vibrations and movement, which can lead to poor surface finishes or inaccuracies.
Copper and its alloys are widely used in various industries due to their diverse properties:
Electrical and Electronics: Wiring, connectors, heat sinks, and circuit boards.
Automotive: Radiators, heat exchangers, and brake components.
Marine: Piping systems, propellers, and marine fasteners.
Aerospace: Bushings, bearings, and hydraulic components.
Industrial: Valves, fittings, and machinery components.
In summary, copper materials in CNC machining offer a range of options tailored to specific applications, combining machinability with desirable properties like conductivity, corrosion resistance, and strength. Proper tooling, cutting parameters, and workholding techniques are key to successfully machining copper and its alloys.
