Our CNC is as dust-collected as I can get it. We have a Busellato flat table router. We mostly cut MDF or MDF core material. The amount of material left is astronomical. One of the problems is that the shroud seems to be elevated too high above the router bit. From a glance, I didnít know if the shroud could be lowered. Also, even if that first problem was resolved is there an external auxiliary vacuum to dust collect?
From contributor A:
Dust hood heights can be tricky, depending on stock height and length of tool. You don't want to wreck the hood if you are using a short tool, or very thick stock and a long tool. You can probably mechanically adjust it down a little, probably less than an inch. You can also run an airline to blow toward the tool to help dislodge chips and get them airborne at the site of the existing hood position. Finally you can hook up a wand on a hose using the existing vacuum system to sweep off the table. I do that instead of blowing the dust off the table and making all that cancer causing dust airborne. It is better to just knock the dust off the table to the floor and sweep it than to blow it off if you can't hook up the hose and wand. Wear a mask!
