Just my two cents worth......

During the initial design of our plasma system, we also were concerned with material handling. We decided to add 24 ball transfers (McMaster Part # 6460K42) on...

I'll Try......

1. The motor and gear box are mounted to a (moving) flat aluminum plate.
2. The Cars (4 of them) from two THK Linear Slides are bolted to the same plate.
3. The THK rails are...

No, we didn't go with the preloaded helical gears. Actually, I planned on it, but they (Atlanta Gear) actually talked me out of it! We went with hardened pinions and preloaded them. Thanks!

The hatches are for access during the initial assembly of the equipment and if something fails (I hope it doesn't!) we can remove what we need for repairs. Attached is a photo of the aluminum...

The gas shocks, the ball ends, and the ball mounts all came from McMaster Carr. The shocks I picked are listed below. They come in 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130 force lbs. ...

This was NOT cut on a Hi definition Plasma....... Sorry Jim....I had to!


Attached is the .DXF File in case anyone wants to experiment.

Tom,

Attached is a close-up photo of the "mortise and tenon" of the gantry. The whole system was built like this. I would say to the guys in the shop "if the tab fits....weld it!" It takes...

Why? Because I didn't buy Hypertherm? or are you peeking thru our back door again....... :)

I personally regard you as one of the most knowledgeable people on this forum, so if you say it can't...

Hi folks,

I just thought you might want to see what ended up with our Robotic / Plasma Table. Thanks to all of your help here on the “cnczone” and the “unbeatable” customer support at Dynatorch,...

I was just wondering has anyone ever attempted installing a close meshed electromagnetic field under the cutting slats that can be turned on during the cutting process to collect the "plasma dust"...

A Perfect Example!!!! Thanks!

I am sure there is more qualified people here to address your chatter problem, but in viewing your photos, it would appear to me that your pinion gears are too small which causes the pinion to want...

I would love to re-visit Camsoft, but I can't get anyone to return my calls. When I call the office #, an answering machine picks up. Are you suggesting camsoft would be the better option?

BTW:...

I agree in regards to the section of the belt that is not engaged is the weakest link. I am also assuming (and I may be totally off base!), that the belt itself being made of polyurethane could be...

Thanks Karl.

Your suggestion is exactly where we are at. We have reduced the weight to the point where two (side driven) 34 frame motors mounted to gear boxes with Helical rack and pinion gets us...

Mike,
I love your idea / concept. I read thru this thread and I am VERY impressed with your design. I am assuming that you are not selling the belting / pulleys yet to us DIY’ers and I looked at...

Well, I'll Make you a deal you can't refuse on two of them ! :)

Thanks for the quick response!

As for your first statement, I didn’t quite understand the “pivot Line” comment. We currently have it set up to run straight up and down on two sets of THK Linear...

I have searched the “heck” out of this site looking for an answer and trying to avoid repeating a question, so if I missed something, please let me know…..

I have a question about “pressuring” the...

WSS,
Thanks for the inverted Thomson bearing drawing. When I pulled it up, it was amazing how similar your drawing looked like mine! I was doing the exact same thing. Inverting the rear (right)...

WSS,
Thanks for the reply. Yes, I would be interested in your "inverted design" if it's not too much trouble. When you say limitation ($$$), due you think the acceleration could be achieved with...

Hello everyone.

Last week when we last spoke………ok, Ill admit it, it been a little longer than a couple of weeks! More like 4 years! (You know the drill, new marriage, new daughter, business is...

I also have a similar question...

Would a belt drive work in lue of a Rack & Pinion?

I was wondering the same question as "Freak Brain" and had decided that a ball screw for the 8' movemnet (on...

MMT,
I was wondering if you may have found a "reasonable" source for "supported Thompson Rod" type shafts. I am in the market for two 10' long 1.5" fully supported shafts.

Thanks everyone for the help in making this decision easier. I understand the complexity of the robot, not to mention the added issue of the gantry, the limited reach (cutting path), but the deal...

To everyone, thanks for all the input. A question rwas brought up ecently in our office was the feed rate (ipm) of the robot movement ( I know... This should have been considered before now!),

We...

Thanks,

Actually, the table doesn't tilt, the table has ball transfers that will pop up to facilitate material handling (See photo). The angle of the table is configured to allow slag to "slide"...

Thanks for the reponse. I actually have two of the Asea L6/2 robots. One is on a 5' slider. This allows us to cut approx 42" out of an 48" X 8' sheet of metal. Hindsight, I would like a slightly...

Hello everyone,
This is my first post to this forum. I have been reading for awhile as an anynomous user. I am very impressed with the knowledge out here. Anyway, back to my question.

I am in...
