I didn't take a look at the file, but my typical approach would be to extend the surface geometry whatever is needed to get the proper engagement on the first pass your looking for.

They vary pending on application, HT800's RT100T's , these are the ones we use majority of the time. I believe they have 25 or 30D in these as well.

"So you are using a .75" drill that is over 12" long with spot only? And you get good size and hole location?". That is correct sir!

I'm sure you guys know this as well, but if pre drilling you must use the same or greater drill point or you chance breaking the drill or walking which will ultimately lead to the same event. Following this guide line along with perfect indicated tooling gives us dead straight holes within .001/.002 at those depths.

Guhring, its the only way to go! Great quality in deep hole drilling. I actually contacted them before hand, they specifically said to use 140 deg. spot before hand only. Almost 1000 parts in on this one job in particular and I'm a believer. I will say I haven't got up to there recommended speeds and feeds, but very happy where were at. edit: I do want to state the no pre drill hole is a 3/4 dia. , we do however pre start the 17D hole only because it is a .296 dia drill and worried about breakage that other tooling would suffer from on connecting ports. Even so, we only pre drill .25 deep so we can enter/ ramp spindle and have at it without affecting the hole geometry as these are AN- ports.

Absolutely agree, we drill lots of 15-20XD holes this way

Maybe a stupid question, but are you using the calculator for depth and entering the tip flat dimension? At the machine it will be correct, but verify does not show tip dia., just a point so it will verify incorrect. If you need an accurate verify you must build a custom tool.

Well it seems that a MAC air selinoid is the issue, a Taiwan part made it our American built Haas! The next issue is parts availability, no vendor in the states has one(6wks out). And our Local HFO, doesn't want to return e-mails or phone calls. Seems our next purchase will be more Doosan's and trading in our Haas's. I hate xxxx poor customer service!!!!!

Thanks for the reply's guys, but maybe I should be a little more clear. The bang we get is more from the tool arm, not the tool. Seems as if some times the tool pot is not fully down before the arm engages the holder in the pot. We've tested this in the recovery mode when it repeats, looks almost as if the arm pulls the pocket into place.

Any of you lucky Haas owners ever have any issues with the tool changing arm on a VF5? We have a 2010 that wants to occasionally stick and or bang while tool changing. We've had our service rep stop in and look it over, nothing was really ever found. The tool holding plungers operate fine, though the tool pot is occasionally slow to come down. It does have over 600,000 tool changes, but as do our Doosan's, and never a problem there. Any input is appreciated.

In the past with some castings we probed the part to establish 0, or any given location. Do you have these capabilities, works very very well, even in 5ax situations.

Like FOGHORN stated, start at one location and work your way around. I use transform all the time, but NOT ever sub programs from them. IMO, MC could use some help regarding area's such as this. Wait until you program a 8 station fixture on a dual platter trunnion 5ax. Loads of fun, working on our 3rd multi part fixture for a dual 5ax now, almost impossible to not hand edit some. What kills me is winding up the B axis, then the wasted time unwinding. Arrgh!

Can't say I've ever turned or milled it, but I know from Tig welding it will tear up the grinding wheel when sharpening tungsten. Not sure if this is similar grade stuff your looking at, just my 2c.

Same here as what HTM01 stated, place a unclamp of both axis before simultaneous action. We do fully 5ax porting here every day, no problems on the Doosan's, but the Haas's seem to clamp/un-clamp. Not as bad as every posted line, but they will do it often and dwell in the port. The solution, make it unclamped until done with that tool path. And yes the Doosan's with 31i a5 and Tsudakomo 5th's blow the Haas's out of the water on speed and quality all day every day.

Yo Doug, thanks for the info. Yes we are aware of some of these potential issues, that being said, all of these can be addressed. All of our machines have spare codes that can be fired, and yes end arm tooling or sharp edges need to be taken into consideration. That being said, we are mainly looking for these to attend our lathes with smaller parts 1-8 lbs. How have these units held up in the field? Anything to be aware of if we were to purchase some of these?

We have actually been looking into this for some time now. After going to IMTS, we are looking at the Universal robots from a cost and no cage perspective. www.universal-robots.com These seem pretty robust and easy to set-up and move machine to machine. Best part is no cage is needed to hinder operator work space and valuable floor space. Cost for their largest unit is less than a small lathe, installed with training.

I'm with Ron, works fine and as intended here. No spring pass unless overlap is configured.

I am think maybe at 10% you are a little high, which could cause the foaming. We also have to add a slight amt of de-foamer in our high pressure applications, I'll get you the brand and amt we use shortly. I know we add very little maybe once a month to solve that, maybe a bottle cap or two .

Newbeeee; I'm glad to see someone else is running Houghton's 795, we switched to that maybe 2 years ago and its been great. We run 795-B about 8% concentration and it pretty much rocks.

Sticky: we are running "Oil Services" Way lube 68, which we have been for awhile now. We called our rep again and told him we needed to switch to a name Brand such as Mobil. I also guess these are a more clear blend, rather than slight tan? I will say "Matthew" has me worried, as I wondered the same thing on mixing the oil, not to sure/keen on running Kerosene thru the system. Our Doosan service guy said the same, should just switch and jack up the timers till the old is ran out. Hmm, that's a good point! Never thought about it sitting on the floor, but then again it always has. We will be changing that now, Thanks

Our Rep stopped in and took a sample for testing, funny you mention that, as he did as well. In 20+ years of manufacturing I have never seen this happen, and slightly worried, though he says not to be. Supposedly there is a tackifier in the lube to allow adhesion to ways, wondered if the content was to high, or if the Drum got cold. As far as I'm aware it is a blended mix, non synthetic nature. Aside from waiting to hear back from him what is anyones thoughts on what we should do?

We just recently have seen a problem with our way lube in a few machines where the lube in the machine tank appears to have a Gel appearance. This is not the entire product, just where it touches the holding tank or pump parts. We have our supplier stopping in today, but wanted to get opinions/advice if others have ever seen this happen and what the cause was. This is the first we have ever ran across this, and frankly I'm worried as this is the life blood of all machines as we all know. Any thoughts are much appreciated.

GregJ, I couldn't tell you an exact tool for the same reasons/questions Ron asked about application. But I would push to have your tool reps allow for you to test any tool before purchase as ours do. If they work as advertised or better than what we are currently using we buy them, if not they leave a week later with the salesman. Its a win win situation on your part only buying what works.

Press MDI, then Pgrm/conv, then type debug, write/enter. You will know your in debug mode when the program #'s are xxxxxx. Don't forget to exit debug mode! And wow bass, you revived an old post from the grave.

It will last virtually forever, given proper coolant/speeds-feeds. Current production run in house 1"-16tpi .875dp female threads, we have currently run over 1600pcs and have only had to make slight wear adjustments. Zero burrs, and this tool even chamfers the lead in. FYI this is a single pt. 4fl SCT carbide thread mill.
