Cutting Aluminum Composite Sheets
Question
Forum Responses
From contributor F: I use a 1/4" O flute with great results. 180 ipm 100 ipm plunge 18000 rpm. From the original questioner: Are you using any coolant? From contributor F: Can't use coolant when you have an MDF bed. From the original questioner: So no air coolant or anything, just single cut at those speeds? I'll give it a shot. From contributor F: I did actually buy a Vortex Tube for air cooling, but don't have a big enough compressor to keep it running. I realized I didn't take the time to research this specific material, so my comments may be misleading. The material I have worked with has a thin layer of aluminum on both faces, pre-painted black, with an inner layer of abs or hdpe plastic, not corrugated. Overall thickness is .125. Hope I didn't cause any confusion. From the original questioner: That's the same stuff. The max metal I have cut is white with black core. It’s very thin aluminum faces I just have had trouble getting clean edge. From the original questioner: I cut a bunch today with a new O flute from MSCdirect. I ran it at 180ipm 18,000 and it cut much better. I think I was running it too slowly before. I'm cutting pretty small parts and I really wish the masking film on the Max Metal was thicker. It’s near impossible to not cut through it. From contributor F: We use a double sided masking tape to hold down small parts in addition to the vacuum. We get it from Bron tapes, and they cut it 1/2" wide for us. It’s super strong stuff and sticks fine to the MDF spoilboard. From contributor G: We have been cutting a bunch of the reynobond. I use a 3/8" O flute from Onsrud. Material thickness is 4mm. Spindle speed is 16k and feed rate is 400 ipm. After cutting a whole sheet the tool is only warm to the touch with the shavings containing the heat. The cut is nice and clean and no burrs.
