Copper is a versatile and widely-used metal in various industries, thanks to its excellent electrical and thermal conductivity, corrosion resistance, and ductility. Machining copper can be challenging due to its softness and tendency to produce long, stringy chips. To achieve a high-quality finish and prolong tool life, it's critical to select the appropriate Surface Feet per Minute (SFM) for your machining operations. In this blog post, we will explore the factors that influence SFM for machining copper, discuss different machining techniques, and provide practical tips to optimize your processes.

CNC Machining Aluminum materials is one of our most used materials. We support clients to turning, drilling or milling on aluminum material from size 0.5mm to 470mm

3. Machining Operation:Different machining operations, such as turning, milling, drilling, or tapping, have varying SFM recommendations. The complexity of the operation, tool geometry, and required surface finish all contribute to determining the optimal SFM for each specific process.

2. Copper Alloy:The specific copper alloy being machined also impacts the SFM. Pure copper is softer and more ductile than most copper alloys, which can lead to a higher SFM. However, harder and more abrasive alloys, such as beryllium copper or tellurium copper, may require lower SFMs to minimize tool wear and achieve a good surface finish.

Our CNC Machining Plastic materials includes ABS, HDPE, LDPE, Nylon, POM, Peek, Polycarbonate, etc. We produce them in high precision and high smoothness.

1. Turning:Turning operations, such as facing, grooving, and parting, require careful selection of SFM to achieve a smooth surface finish and minimize tool wear. For turning copper with carbide tools, a general SFM range of 600 to 1,000 is recommended, while HSS tools should operate at lower speeds, typically between 200 and 400 SFM.

CNC Machining Titanium material brings components superb features, we use titanium to produce high precision work-piece for clients from aircraft, aerospace, medical devices

2. Milling:Milling copper involves removing material using rotating cutting tools, such as end mills or face mills. The recommended SFM range for milling copper with carbide tools is between 500 and 800, while HSS tools should operate at speeds between 150 and 300 SFM. Using climb milling techniques can help reduce the formation of long, stringy chips and improve surface finish.

CNC Machining Copper Parts are widely used in the manufacture of electrical wires, cables, electric brushes, electric spark, and other electrical devices and products.

Our monthly production capacity are around 200’000PCS for turning parts, 100’000PCS for milling parts, 100’000PCS for turning and milling parts, 1’000’000PCS for forging and extrusion and sheet metal fabrication parts

3. Drilling:Drilling copper requires careful consideration of SFM, feed rate, and tool geometry to prevent work hardening and excessive tool wear. For drilling with carbide tools, a general SFM range of 400 to 800 is recommended, while HSS drills should operate at speeds between 100 and 250 SFM.

In conclusion, selecting the appropriate SFM for machining copper is crucial for achieving a high-quality finish, minimizing tool wear, and optimizing overall machining efficiency. By understanding the factors that influence SFM and implementing the recommended techniques and tips, you can ensure successful copper machining operations and improve your production processes.

4. Tapping:Tapping copper involves creating internal threads using a rotating tap. The SFM for tapping copper is generally lower than other machining operations to minimize the risk of tap breakage and ensure accurate thread formation. For carbide taps, a recommended SFM range of 50 to 150 is suggested, while HSS taps should operate at speeds between 30 and 100 SFM.

CNC Machining Copper material is soft and easy to machining on different shape of components. We mostly produce copper components for electric devices by machining and stamping

4. Coolant and Lubrication:The use of appropriate coolants and lubricants can significantly impact the SFM during copper machining. Proper lubrication helps reduce friction, heat generation, and tool wear, allowing for higher SFMs and improved surface finishes.

Select the appropriate cutting tool material, such as carbide or diamond-coated tools, for increased wear resistance and higher SFMs.

Asianstar many CNC and stamp machines allow us to produce various copper parts, different sizes, and structures are all well done by suitable solution

1. Tool Material:The choice of cutting tool material significantly affects the SFM. For example, high-speed steel (HSS) tools typically operate at lower SFMs compared to carbide or diamond-coated tools. Carbide tools are generally preferred for machining copper due to their increased wear resistance and ability to withstand higher cutting speeds.

CNC Machining Brass material is used for wide range components, we support clients to produce a variety of parts such as gears, locks, electronics, pipe fittings, etc.

Copper has a shiny reddish-orange finish, which varies slightly based on the surface finish method. Copper can be media-blasted and polished to achieve many different cosmetic surface finishes.

Surface Feet per Minute (SFM) is a measure of how fast the cutting edge of a tool moves across the workpiece's surface during machining. It plays a crucial role in determining the cutting speed, which directly impacts the quality of the machined surface, tool wear, and overall efficiency of the machining process. Selecting the appropriate SFM for copper machining is essential to avoid excessive tool wear, work hardening, and poor surface finish.
