I wonder will this cut an Iridium 0.028" diameter pin how square will it be, what thickness of cut and how accurate would it be.

[janotosinnumeros]

i have no interest in machines and metal and stuff...but it's actually fun to watch a video like this

[dogfightvj]

wow, that's how they do it

Hi, I need a few pieces of 1/8" aluminum cut with plasma. If I provided the vector/line drawings, could you give me a quote or do you not accept this kind of work? Feel free to message me and/or provide me your e-mail. This is just a small job for a hobby/modeling project of mine.

[greenjeens]

Ya, those videos of the gantry traveling at those speeds were pretty amazing, never seen one move that fast.

[greenjeens]

I noticed theres no gear reduction for greater resolution and torque, but it still cuts at a decent speed. I have seen your ads on ebay for this machine. In this video what motors are on here. I know there nema 23's but are they the 620oz version?

[elvis1669]

@greenjeens

This video is of our first prototype machine 20 minutes after first turning on power. The motors are the Automation Direct nema 23 276 in-oz with a geckodrive and current setting of 2.7amps. Direct drive, it can easily achieve rapid speeds of 1000ipm and a acceleration rate of 50 in/sec/sec. The candcnc.com 300 or 620 motors will give you the exact same performance.

[flguy32501]

Is this home made? NEMA 23 steppers? What CAM and controller software do you use?

[elvis1669]

@flguy32501

This is the first prototype machine for Precision Plasma LLC 3 + years ago. It uses nema 23 stepper motors direct drive running sheetcam and mach3.

lollllllllllllllllllllllll ive just realised ive been watching plasma cuter and laser cuter for the last 30-40 minutes haha

[rodicaxplod]

very nice!can you adapt a cnc milling machine in a plasma cutter? you only need a steel table and the cutting torch.is that right?!please answer.

[SMG59]

i want one of these for christmas lol

[elvis1669]

The cnc gantry has a resolution of .00098" or .0249mm per microstep of the motors direct drive as show or twice the resolution with the optional 2:1 belt reduction units. You would then need to look at the tolerance of the gear rack, but the biggest limiting factor for the tolerance is the plasma stream itself.

[lexichronicle2]

@elvis1669 thanks for including the metric of that.

i did spend a while wondering about how to increase the resolution of the stream. it is electrically charged, which means it responds to magnetic fields, so I was looking at using coils around the nozzle to better define / control the jet. one neat possibility would have been cutting tighter internal corners & higher tolerances in general without the cost of lasers

but, as with many patent possibilities, someone else has also had that idea :)

[rvantwisk]

@elvis1669 Don't get fooled by microstep resolution, your are properly more close to 0.249mm/step

This is what I see at least on my router (Wood router)

[cjellwood]

I guess we are not talking 0.2mm tolerance here?

[herrmc]

Are you willing to share your .dxf file? I really liked the pattern you cut out.

[flyjackflay]

sure it can disintegrate steel... but can it make me a sandwich?

[rocketlauncher96]

nice design!

[donkekeli]

why dont you have a the watery stuff under the table? I always thought it was a prerequisite

[Ebdan88]

How tick can this mashine Cut?, and is it possible to make your own, or buy a kit like you do with small and medium size cnc mashines? thank's

[elvis1669]

@Ebdan88

The thickness is based on the plasma cutter used. I use a Hypertherm 1250, which can cut 5/8" in a machine operation. Other plasma cutters can cut thicker material.

[fishandchipsandpeas1]

just a little quicker than i take with my fret saw.

[luxiusII]

How much does it cost this machine???

i want one...

great video ...

Thanks

[crisacos143u]

1:07 FAIL, XD 5/5

[Foudremen]

Hi!

I like this video, but have to see the motors what running in this machine. I dont believe if theyre the stepper.

Thanks

[samakable]

From your video, The direction of cutting is not correct.

inside should be CCW

Outside should be CW

[dude2699]

I agree I run our CNC Profile at work and thats the direction it goes

[elvis1669]

You are correct. This video was made 20 minutes after assembling the table and it was accidentally programmed backwards. Cut quality is better if it is cut as you have stated, but it is still a good example of what a machine can do.

Best Regards,

Ron Chacich

[Fluidistor]

Why is it so important to cut inside and outside CCW / CW?

[elvis1669]

@Fluidistor

The plasma uses swirling air to make the cut, which makes it similar to a spinning machine tool. Because of the direction of the swirl, one side of the cut will be of better quality than the other. In this video, the edge quality on the part would have been better had the part been cut the opposite direction.

Best Regards,

Ron Chacich

[IZIPPLE]

Is the video shown in actual time or elapsed time?

[elvis1669]

The video is made in actual time. Thanks for viewing.

[vladicapn]

Nice, I was made plasma cutting table with waterbed and work fine too...There is no gases

[baccus61]

How do you clean out your water table,Vladicapn? Do you drain it then scrape all the crap out or do you just use a magnet covered in plastic etc?
