Guys, This is for a dust collection system on a CNC mill, where I am machining a SiC composite dry. The 1250 CFM is not adequate to effectively draw the dust completely away.

Take a look at the picture again, it will go along with my description. The top plate is 18" x 48" x 1.5" thick. Every 1.25" there is a 1/2-13 drilled and tapped hole, with a 5/16 thru hole; staggered between the rows and columns, is another 5/16" hole, but with a 1-1/8"x 60 degree counter...

I understand. My goal is to increase the efficiency of the dust collector that I added a few posts ago...

Thanks for the input. The hole size issue was the first part of my question. Take a look at the picture...it is a "sealed unit", and I have 2-6" collection ports at the front...

Arjan82, Thank you for the reply. No, above the plate with the holes, it is open, not a chamber. See the attached picture of a dust collection system that I have been working on. The box tube with the holes is to help with the draw of the main dust collection system...

Does this help? Rather than having the holes centered, I probably would move them closer to the face of the plate. The holes are drawn at 0.125" for argument sake...

Thank you for the interest. Which part would you like a sketch of? I will work something up...

Hello there, first post. I am a machinist trying to figure out the following problem, and getting lost in the process. Ok, I have a 1/2" square aluminum tube, 3/8" square inside...48" long, and one end is capped off, and the other, I am planning on welding in an air fitting to induce...

Guys, This looks like a pretty cool site...I'm sure there is all kinds of good information...
