Can the Xzero Viper be used for cutting 1/16" aluminum sheet? If not the Viper, how about the Raptor?
hmm. Any recommendations? I just can't justify the cost of a metal milling machine just for cutting 1/16" aluminum sheet.
The ViperXZ would have no problem with aluminum
Great! If the Viper would suit this need, what advantage would the Raptor have over the Viper? The Raptor is beyond my budget at the moment, but if the advantage is worth it, maybe I'll hold out until I can afford the Raptor. I'm just a bit unsure about the Viper because I see the gantry wiggle a bit left and right when it moves in the ViperX video.
Also, what's the preferred method to brace aluminum sheet when cutting?
you need the right speed and feed to match the machine rigidity. with the viper youd simple cut a little slower than the raptor.
on the raptor though the machine itself was the least of my worries. fixing sheet is a pain. a vacuum might do well, but it depends on how big the item you are cutitng is. screwing the piece down at multiple points may be the most effective if its a small run or one off job.
When I watch the ViperX video in full screen, at 16 seconds into the video I see the top of the gantry assembly wiggle left and right during the end stops of full speed movement, and maybe it would never wiggle under normal cutting speeds. I don't know, please bear with me because I'm fairly new to this.
This would be for in-house prototyping pieces that range in size. Possibly for small runs as well. I'm thinking maybe bolt down the pieces and leave tabs in the paths, or some sort of onion skin method I seem to recall. Yes, with an onion skin, a vacuum table can be used.
The Viper can readily cut 1/16" aluminum sheet in a single pass for small production runs?
its almost purely down to getting the work not to vibrate and the correct feed and speed.
id recomend agans the onion skin idea though. cutting works better when you go all the way through rather than slotting. less binding in the cutter and therefore a nicer finish.
i cant see the video though. if your talking about movement under acelleration when its not cutting, you are most likely seeing the entire machine move. the force of acceleration easily shifts the machine around on its little rubber feet. theres is going to be a small degree of "bounce" in the motion too, but it should be tiny and definitely not visible by eye or in a video. can you find the video on youtube and post the link?
Found it on [nomedia="http://www.youtube.com/watch?v=sMiXv2Lhz04"]YouTube - ViperX.mp4[/nomedia]. Hit 720p and then fullscreen. I see it most at 29 seconds.
To be sure, the Viper can readily cut 1/16" aluminum sheet in a single pass for small production runs?
i will say that i was not thinking of that machine. i was thinking of the bigger viper round rail machine that we demod cutting aluminium.
i would say that it *should* be fine cutting aluminium slowly in 1 pass, but ive never actually used that machine, so ill defer to george.
Thanks. It seems the ViperX uses the same components, but with just a smaller cutting bed than the ViperXZ, so the ViperX should be a bit sturdier I would think. The 16 x 18 cutting bed is as big as we would need. Of course I'd opt for the structural upgrades that I see listed in the price sheet.
