Aftermarket/third-party high pressure coolant

[dsj]

Our shop has a Haas ST-30 lathe and I have a lengthy bar-feed job coming up that has an odd-shaped inside bore. I've done short runs of this part before and occasionally chips will get stuck inside the bore causing all sorts of "interesting" problems. Chatter is most common and broken inserts come right after. If I don't catch it quickly then parts get scrapped. I really don't want to babysit a bar feeding job.

Which brings me to my question. I'd like to add some high pressure coolant to it to run through my tools, hopefully blasting the chips out before they become an issue. We could order it from Haas, but they want about $7k not including tax, shipping, install, etc. for their 300psi unit. Since I have no idea where to even look for a creature such as this, I don't know whether that's a fair price or not. Any suggestions as to where to get something like this? Favorite brands?

Chipblaster is a popular name in high pressure coolant.
FWIW I have 2 used Chipblaster units for sale for $1200 each but I'm on the wrong side of the US for you.

300 psi is right on the edge of piston pump size are wanting to cobble something together or something you plug in and go?

The first chipblasters used CAT triplex powerwasher pumps.
Now they use some oddball imported (Germany IIRC) hydracell diaphragm device.

If you wanted to "roll your own" you could get an electric PW, and add a bunch of standard "whole house" water cartridge filters
to keep the pump safe.

$7k not including tax

In PA anything used directly in manufacturing is exempt from sales and use tax. Pre and post manufacturing is subject to use tax.

The way my accountant explained it to me is up until the stock hits the bandsaw it is pre-manufacturing. Once the part is complete anything else is post-manufacturing. So boxes for shipping and packing material fall under post manufacturing and are subject to sales or use tax.

If you buy a forklift to move material from the rack to the saw then it is pre-manufacturing (and subject to tax), but if you buy a forklift to move stock from the saw to a mill then it is manufacturing and tax exempt.

So my point is adding options to a machine tool is clearly tax exempt in the state of PA. I do not know about other states but would suggest you look into the sales tax code in your state. Sellers are often not familiar with it and will often charge sales tax by default unless you tell them you are exempt.

I know this isn't an answer to the question you asked but maybe it can be helpful

a standard centrifugal high pressure multi stage booster pump will get you 240 psi at 12 gpm with a 3 horse motor
centrifugal pumps if a nozzle plugs it doesn't keep building pressure or over amp like a piston pump does but 300 psi is tough without being in the 10 horse range.

Wanner Hydracell is hands down the best seal-less high pressure coolant pump ever built! Built in downtown Minneapolis Minnesota! If you have problems with it read the instructions and fill it with oil. OEM pump for a lot of builders and aftermarket pumps. I would alway add a snubber to smooth it out…

I've never used one, but these guys can get you up to 3,000 psi.

We had them on a Matsuura HMC cell. Very little trouble over the near 20 years before the cell was sold. Too bad I can’t say the same about the mills themselves.

Had several Chip Blasters too. They were pretty good performers. Staying on top of the filtration is a good thing regardless of the brand.

I run a twin spindle QuickMill HD2 with two of those, one for each spindle. We've got them set to 1500 psi max. They are about 12 years old now and have never given any issues.

A temporary regulated max pressure can be set with an M code. We also installed a manual override knob on the machine control console so that the pressure set by the M code could be divided even further if needed while in operation. The system works very well.
