Spoilboard clean up between cycles3/12
What are most people doing to clean their spoilboard in between cycles before loading a new sheet of material. One machine we are using a shop-vac and the other we are using a single bag dust collector with vacuum attachments and vacuuming the table before blowing the remaining dust off with compressed air. I have looked into some of the pneumatic driven industrial hi-vac but you need an air compressor the size of an 18 wheeler to run them. Looking to make improvements in this process and improve overall dust collection, while considering combustible dust regulations, etc.
I wrote a vac program that goes around the table an uses the vac on the cnc dust collector. Painless. 4" stepover running at 500 in/min
How close do you run your dust skirt to the table surface when you run the cleaning program?
Do you drop off the tool first? This seems like it would be necessary?
Can you post a photo of the machine while doing the clean up?
Lots of different configuration routers out there so it would be nice to see just how you are running this clever solution.
Normally the whiskers of the skirt just touch the spoil board. When running sheet goods the whiskers are flexed. So with no sheets on the table running the sweep program my dc gets MOST of the left over dust I'd say 95%. Good enough to throw another sheet on and cut. I thought about having a air hose ride along and give a little squirt but it hasn't been needed. I call up no tooling for this operation. Leland, yes I tell the machine it's running a 4" fly cutter with 100% step over but call up no tooling.
Wow Dan You either have a lot of time on your hands or don't need much production to be able to run a blank pass just to clean the spoilboard. If the panel has a lot of small parts the operator pushes it onto an offload table then blows off the spoilboard and cycles again. If the parts are larger then you pick the parts toss the scrap and clean the board. But what ever you do the object is to get the machine back to cutting. If the bit is not in the material you are wasting time and money. With a CNC router you will find that faster is usually better and more profitable.
We have a drop off the main dist collector line with a flex hose with 3' of pvc on the end with a modified elbow on it.when the sheet is done running the operator runs it over areas that have accumulation. We then remove parts and blow it off and load a new sheet
Wow Brian heres an idea you run your shop as you see fit and Ill run mine. Dont know if you noticed that air borne wood dust is flammable. I prefer to suck it up as opposed to blow it all over the shop and machine and than have someone suck it up later. and by the way this was not my post Im just offering my two cents worth what works for me.
For years I was blowing off dust with an air gun, just a quick blast after each sheet and hated it. There was not a huge amount per sheet, but besides getting it airborne and having to breathe the dust, it would accumulate behind the machine getting mucked up in the wiring, on the lead screws and on the linear bearings. Mine is a water cooled spindle, but the electronics cabinet suffered all the same.
