Haas TSC 300psi or 1000?

[Mic6]

Well, our MX-520 dreams have been curbed so now we're looking at a VF2SS with a TR-160 trunnion.  We want thru spindle coolant, but is 300psi suited more for endmills and bigger drills?  How small of a drill will it be effective on?

[Machineguy]

Im doing a 1/16 drill at 300 psi. works fine.

I use it all the time. Just keep the tank topped off and  make sure the coolant is draining from inside. The chips in a Haas are a pain.

1000 psi is excellent to have, but 300 psi is better than standard. 4" deep pockets 1000 psi is a must IMHO.

[Mic6]

Great guys, that's what I wanted to hear.  1k exceeds the budget a bit.  We specd thru spindle air blast as well.  Sometimes we drill 6" deep .75 holes in AL.  I hope the 300psi will be up to it.

[Machineguy]

I use a TSP 1.0 " drill 6.0" long with 300psi. Blows thru it with no issues. Steel or Aluminum.

Just getting going with a VF-3SS with a TR160Y.  Got 1000PSI thru coolant and thru air.  So far so good.

I just put in for a new machine from HAAS 1000psi is what I asked for. Please not that in order to get the auxiliary filter you have to buy it on the 300 psi it's not standard. I wouldn't run with out it.

We have the 1000psi on our UMC-750....Works great , BUT , it is freaking LOUD !!! Also , make sure to clean/replace the screen underneath the pump that's in the coolant tank....If that gets clogged , and the TSC tank runs dry or really low , it will alarm out your program.

Does that machine have a top on it?

Nope...

[Mic6]

No top and 1000psi?  Damn.

[Mic6]

Oh, will 300psi drive the small angled heads?

Not very good. If you guys are looking to do RAH coolant drvien then you need to up the budget to at least include the 1000psi IMHO. Really starting to sound like some bean counters with no clue got in the middle of the machine purchase and are doing their best to put your company out of business.

We've needed RAH work on occasion so I was just trying to think of more justification for the 1k system, which isn't going to happen.  Bean counters rule this place.  This giant defense contractor isn't going out of business soon, but they always go on and on and on about competing with the outside and keeping our labor rate down blah blah.  Meanwhile, they order a lot of Fadal spindles, electronics and monitors to keep machines alive.  I'm grateful I'm on a new VF2.

If you plan on running the 1000psi a lot I would look at the brand of rotary union they use. Good quality rotary unions are not cheap and cheap rotary unions fail in far less time often flooding spindle bearings/housing with coolant.

I'm sure Haas would only use the best...

If you hear "chirping sounds" from the top of the machine while running 1000 psi, its a sign your rotary union is going out and needs to be checked.

I will make a BIG mess if it goes.  And cost some $$$ to repair the damage.

I asked about this when we were shopping; they went to a totally new design with ground carbide disks acting as a fluid bearing.  The only drawback is that the spindle has to stop to turn TSC on and off.
