CNC Copper Machining Guide: How to Cut Copper with Precision

Why CNC Copper Machining Matters (Envato) Copper CNC machining is basically taking raw copper and cutting it into parts that actually do a job, think heat sinks, busbars, precision connectors, or small mechanical bits that need tight tolerances. Folks call it a few ways, machining copper, CNC copper, or just copper machining, but it all means the same thing: using CNC tools to shape copper accurately and repeatably. Why T2 copper? Because it's the sweet spot. T2 gives you great electrical and thermal ......

How CNC Machining Delivers Waterproof Aluminum Parts: Sealing, Surface Finishing & Design Tips

When Water Gets In, Everything Fails You’ve designed a high-performance aluminum part, maybe for outdoor use, automotive housing, or marine equipment. You’ve dialed in your CAD specs, picked the right alloy, and sent it off for CNC machining. But then, the nightmare: water seeps in, corrosion starts, and your part fails in real-world conditions. This isn’t just inconvenient. In industries like aerospace or medical, it’s a complete deal-breaker. So how do you make aluminum CNC machining parts that stay......

Top 5 Heat-Resistant Metals for CNC Machining and How to Choose

You choose a metal you think can take the heat. Specs are tight, tolerances unforgiving, but mid-flight, thermal expansion warps the part just enough to cause failure. Now multiply that risk by thousands of dollars in losses or a life-critical application. That’s the hidden danger of not choosing the right heat-resistant metal for CNC machining. It’s not just about melting points, it’s about performance under thermal stress, oxidation resistance, machinability, and long-term dimensional stability. In ......
