CNC Milling For Copper Parts

CNC Milling for Copper

In CNC milling copper, the tools spin and traverse the outer layer of the copper material. Subsequently, the superfluous copper material is gradually discarded until the requested shape and magnitude are created. CNC milling is most common with copper alloys as they have better machinability and produce precise and intricate parts. 

CNC Turning For Copper Parts

CNC Turning for Copper

The process of machining copper parts necessitates positioning the copper components securely. The cutting tools supplied to the workpiece remain static. CNC turning the copper material at the appropriate set rate reduces its size to the required dimension. It is adaptable for many copper alloys and permits the rapid manufacturing of high-precision copper parts. Valves, bus bars, radiators, etc.

Knowing the type of copper is paramount in order to comprehend its machinability. Not all grades have equal machining characteristics.

This is a rundown of some regularly occurring kinds of copper and certain remarks on their machinability.

Copper 122

Copper 122 is a popular choice for CNC machining due to its strength and ductility. It offers excellent machinability, enabling it to be used for complex parts without compromising accuracy or surface finish. Copper 122 also has exceptional thermal and electrical conductivity, making it ideal for high heat or current transfer applications. Its low-temperature strength allows it to be used in cold climates and harsher environments.

Copper C110

Copper C110 has excellent thermal and electrical conductivity, making it ideal for heat sinks, power generators, and other electrical applications. Copper C110 is also highly durable and strong, with good wear and corrosion resistance. It has good machinability, allowing for precise cuts and close tolerances. The material is easy to weld, braze, and solder, offering versatility in fabrication processes. It is non-magnetic and non-sparking, making it a safe choice in hazardous environments. 

Copper C101

Copper C101 has excellent strength and durability, making it ideal for precision machining applications. It is also corrosion-resistant and cost-effective. The copper material allows for high speeds and smooth cutting to achieve superior accuracy and repeatability. It can be used with a variety of tools, such as drills, taps, reamers, end mills, and routers. With its low coefficient of friction and excellent machinability.

Surface Finishes And Post-Processing Options For Copper Parts

electropolishing

In electropolishing, a thin layer of material is taken off the exterior of copper components. This layer usually varies between 0.00254mm to 0.0635mm in size. Hence, this after-processing technique assists in making the surface of your finished copper component even and shinier.

Media Blasting

This post-fabrication technique assists in disguising the imperfections of your fabricated copper components. Bead blasting results in a long-lasting, matte, and more subdued finish.

electroplating

Copper electroplating provides extra protection for the exterior of copper components from corrosion. The metal layers are added without affecting their electrical and thermal conduction. Consequently, this method can increase the longevity of copper parts.

FAQ

CNC cutting speed for copper depends on a number of factors, including the thickness of the material, the type of cutter being used, and the feed rate. Generally speaking, CNC machines are capable of achieving cutting speeds up to 10m/min with a standard end mill cutter. However, depending on the type of cutter and feed rate being used, this can be increased or decreased significantly. For example, using a ball nose cutter with a high feed rate can achieve maximum speeds of up to 20 m/min for thinner materials such as 0.5 mm thick copper. 

Copper is a relatively easy material to mill because of its malleability and ductility. It is also one of the most widely machined metals, as it is used in many industries, from electrical wiring to construction projects. Copper is easy to mill using traditional machining methods such as turning, drilling, tapping, reaming, and boring. Copper can be milled using computer numerical control (CNC) machines for higher-precision work. Copper’s relatively low hardness makes it easier to machine than other metals like steel or aluminum. It also does not require any special cutting tools or techniques, making it an ideal metal for machinists who are just starting out. 

The best tooling for machining copper is dependent upon the application. For general-purpose machining, high-speed steel or carbide tools are the most common. When cutting copper at high speeds, PCD (polycrystalline diamond) tools are often used as they can stand up to higher temperatures and provide a longer service life than traditional HSS or carbide tools. Coated carbide tools may be a better choice if an extremely smooth finish is desired due to their superior edge retention. Some specialty applications may require monocrystalline diamond (MCD) for achieving tight tolerances and minimizing chatter. Each tooling option will have its advantages and disadvantages depending on the specific machining application, so selecting the right one for the job is important.

The best type of copper for CNC machining depends on the specific application. The two most common types of copper used in CNC machining are oxygen-free copper and tough electrolytic pitch (ETP) copper. Oxygen-free copper is a high purity, low oxygen content copper alloy that is exceptionally strong and ductile. On the other hand, ETP copper is an alloy of copper, tin, and zinc that offers superior strength and good corrosion resistance. Both materials are excellent for CNC machining because they can be cut accurately with great surface finish quality and minimal wear on cutting tools. When choosing between these two materials, it is important to consider the application’s specific requirements, such as size, cost, strength, corrosion resistance, etc.

Pure copper is an ideal material for the manufacture of electrical equipment due to its excellent electrical and thermal conductivity, its malleability, and its resistance to corrosion. It can be easily formed into many shapes, which makes it a great choice for wiring, connectors, and other electrical components. With its superior conductive properties, pure copper also has greater strength than other metals such as aluminum or brass. This makes it an ideal material for the construction of power transformers and motors. The only downside to using pure copper is that it can be expensive compared with other metals.
