Building a system for a customer... They are working with a material that
is hazardous but not flammable. They are looking to provide suction at the
tool rather than the typical coolant and want to do something a bit more
professional than a simple wet vac system. Anything you folks know of like
this? We would provide either a pneumatic or electrical signal to cycle the
suction.

My thought is to feed the project with a vortex cold air gun. It
attaches to compressed air and supplies air as cold as zero degrees
Fahrenheit.

One company I worked for bought one for some lathework that had to be
kept cool, but could not take coolant.

If you should decide to go this route, use dry air for the feed.
Otherwise, moisture will condense and freeze in the discharge nozzle
and cause the gun to shoot tiny ice balls around the room.

Hmm, that leaves out plutonium.
Uranium?

Asbestos, Caffiene, coal dust....

You guys are making it really complex.

One place I repaired a few machines at machined nothing but synthetic
graphite. A rather hazardous substance to the machines at least
(conductive and abrasive). They had one hell of a big dust collection
and separation system, reported to have sucked up a 1" micrometer that
someone put down too close to one of the nozzles, had about a 20'
vertical lift to the ceiling too. It was a while ago so I have no idea
who made the system, but if you check around for a company machining
graphite molds for aerospace stuff they should have some leads.

Don't know anything specific, but there are pneumatic powered shop
vacuums that generate absurd suction and flow. Far more than electric
vacuum cleaners do. Should make enough wind that it can cool things
off. You might go look up a few manufacturers and call them about your
idea.

I used to modify wire wrap connectors for a customer. The base material
looked for all the world as if it had asbestos fibers in its composition,
although I don't know that it did. This was long ago, in the '70's. One
of the operations was to fly cut both sides of the connectors after they'd
been sawed from a larger one. I modified a commercial vacuum fitting by
machining a radius in keeping with the spindle of the mill, so it would
partially surround the fly cutter at the point of cut. It was then mounted
in a quickly made plastic mounting that clamped on the quill of the mill.
By running a large shop vac without a filter (much better air movement),
placing it outside the shop, it picked up virtually all of the dust coming
off the cutter, dumping it outside. I still have the setup, although it
rarely gets used now. You could do something similar, maybe incorporating
a cyclonic separator.

They make a product called a "line-vac" that is a vac generator... used
to convey small parts. I've used them to eject parts from a piece of
automation. Pretty impressive flow...

all you have to do is hook up a solenoid valve to it and provide a
signal.

could work...

How much suction is going to be required? How big of a collector is going
to be needed? There are units available that range from filling a couple of
garbage cans, to filling something that needs to be taken out by semi.

You may want to start he
http://www.donaldson.com/en/industrialair/products/ I'm sure they have all
sizes.

If you are anywhere around Minneapolis, I may have a used unit that may fit
your needs, but you'd need 3ph power.

I recall Boeing's R&D working on a chip vacuum for their "small" and
hand drill motors. They tried like crazy, but the chips jammed and clogged
like crazy. There needed to be a chip breaker that wouldn't clog, and a
transport system that would remove the chips without clogging and going to
hell so easily. They gave up, and just insisted that we vacuum up when
done.
If your customer's materials don't create any long chips, a short
sleeve, spring loaded to the surface of the material, sized slightly larger
than the drill bit to prevent clogging but allow cuttings to roll out, and a
vacuum body just above that will draw the chips away from the cutting
surface where they can be drawn away. You'll need a high vacuum to avoid
clogging and keep the vacuum working all around the drill bit, but obviously
not a high flow. This I seem to recall was the idea with Boeing's thinking,
but aluminum and sharp drill bits creates hardened continuous chips, and
their chip breakers weren't up to the task.

ASHRAE has a pretty useful HVAC handbook that covers air velocity
requirements for effective dust, chip capture etc. Also covers useful
info on duct pressure drop calculation, transport of material in ducts,
design of hoods, tool shrouds, and dust capture for work areas. Couple
of hundred pages with lots of examples. Probably runs 25-30 bucks.
Maybe Amazon has a preview you can look at to decide if it's what you
want, or you can find a copy at a library.
