I'm mostly finished my CNC (I bought a kit from <a href="http://mydiycnc.com">mydiycnc.com</a> and finally received it), and am looking at fulfilling my plans to build a modular synth.<div><br></div><div>A synth module usually consists of a circuit board attached to a metal front panel. The power is supplied via a backplane and the modules are a standard height/width so you can mix/match modules to build your synth.</div>
<div><br></div><div>Using a CNC for circuit board milling is straightforward, but I am trying to plan out how I finish the synth panels from raw aluminum.</div><div><br></div><div>My basic plan is cut the aluminum to size, paint it, then use the CNC to engrave text and a drill guide into the panel.</div>
<div><br></div><div>For cutting:</div><div>- can cut 2mm or 3mm sheet aluminum to a very precise measurement (+/- 0.5mm) with a simple aluminum brake? I guess I could use the CNC to mill a guide line but am trying to minimize CNC wear and tear.</div>
<div><br></div><div>For painting:</div><div>- I was considering getting an air compressor and gravity-feed HVLP sprayer to paint the aluminum. This is similar to how cars are painted but I'm worried that the paint may flake when I engrave text. The alternative I guess is buying pre-painted panels painted using an andization process but I'd prefer to DIY it.</div>
<div><br></div><div>Then during the milling phase I would engrave text and drill guide onto the panel before drilling out the holes with a drill press.</div><div><br></div><div>Does anyone have experience working like this with aluminum? Paint choices, cutting tools, etc, I'm all ears :)</div>
<div><br></div><div>Thanks</div><div>Tom</div>
