General Mach Discussion / big router vacuum tables ?!?

« on: January 04, 2006, 02:12:16 PM »

Ok so in pictures of vacuum tables I have seen it looks like holes drilled through to the table connected to the vacuum supply. My question is if you don't have the entire table covered with a part, doesn't the vacume just suck through the open holes, how does it hold the part?

Yea I think you guys ar right, that is what I was afraid of. hhhm back to the drawing board. i guess i will just go rent one of those magnetic beam drill presses. 119 holes drilled and tapped for the linear slides + 36 for the support rails * 2 = pain in the a**. not to mention the Y and Z...

lol, what ya gonna do?

General Mach Discussion / Plasma cut holes question ( plasma experts welcome! )

« on: December 27, 2005, 02:01:31 AM »

Hey all, I am building a BIG 5axis gantry router, and on the X steel support beams I have 5 cross braces that will bolt to it, and bolt to the other side of the X. I am going to have to drill and tap 36 holes on each side and I was thinking about building a walking cnc bot to make the holes for me. Basically my plan is to build a little "car" that drives on the rail and has a Y slide axis to mount the plasma torch to. Basically it will ride along the beam (X) and it will have a slide for (Y) with a plasma to cut the holes for me,  I am going to treat it like a 12' x 6" cnc plasma cutter.

My question is what happens to the edges of the plasma cut hole? Does it get heat treated via the cutting? Will this affect the ability to tap the hole afterward? I also have to drill and tap a zillion holes for the linear slides so I think the bot should save me a bunch of time.

That is awsome! I am envious, I am moderate to advanced -mechanically inclined, advanced electronically inclined, but can't program to save my life.
