I used to be a chemical salesman way before I knew what a cnc machine was and one of my customers over in chattlesworth, ca did a lot of contracting for haas enclosures (I sold them the stamping fluids, cleaning chemistry and paint adhesion chemicals) and there QC was terrible (like actually of the 100+ customers i had they were the worst). It was one of those grandpa left the company to his 2 grandsons things (i wonder if there still in buisness). But I remember seeing all the panels coming off their conveyor line and thinking "the paints going to fall off this pannels in about a year" skip 7 years ahead and I own 2 2014-2015 haas and I love them.... but I was right all those years ago their phosphate tank was always, and I mean mostly of the time (not literally always) way to high so the steel had so much iron phosphate caked on that the paint would not stick so their solution was to dump more final seal tank chemistry (contained a decent amount of zirconium hexafloride and Hydrofloric acid) so the acid would eat away the excess iron phosphate.... I wouldnt say it really ever worked well this comment was an essay but even with haas cheaping out of the paint, I love my 2 little machines to death
The key is how does the 5th axis fit with the entire value stream. If every cycle you turn out more parts than the downstream operations can handle it messes with your one-piece flow. What options are available for inter-machine parts handling so the operations are time balanced? Yes, the best setup is to not do a setup at all, but only if it makes sense in the greater scheme of things. SMED analysis can go a long way in balancing things out.
The compromise is compactness vs rigidity in how to layout a traveling column machines. If the stack for the y has the trucks on the main column and the rails on the spindle ram ala Haas the machine is smaller cheaper and easier to manufacture. The problem is the effective overhang of the spindle ram changes based on the y position. The alternative is to mount the rails to the main column and put the trucks on the spindle ram. It's bigger and heavier but irregardless of y position the effective overhang is the same. DMG and doosan traveling column machines are like this, I'd assume most elite machines are made this way.

Love the video. Never found use for the hand control until I used it to tram in the 4th axis on VMC. Because you just hold it for .1 moves instead of turning the handle made life much easier. But i regularly swap head stocks and collet holders on a rotary. So it may not be worth it for every one
Thank you for the video, the climb vs conventional idea for shallow finishing sounds really interesting... I am definitely going to test it. I run very light duty 5 axis and I wonder if it makes a difference in the finish.

Man I preach conventional cuts quite often with much resistance in my world. Nice explanation of cutting theory. I just had a part that was asked for extremely tight profile tolerances(as low as .0004🤯) with areas of thin tall walls(some sections 4.8"Depth and as thin as.024" thick). After alot of trial and error the solution was conventional milling paired with leaving more material on the thin sections .016" on thin walls, and .003 finish on the thicker profiles. Tough challenge especially because it was a high nickel stainless. 💪💪 another rule of thumb is cut the floor separate from the walls. 2 separate tools in my case for the best outcome.

Hi. Just noticed this video. Agree with everything you said. I ran the UMC-750SS and it had the same issues. Loved the M/C, but I am thinking about getting a VF-4SS and adding a trunnion rotary table (TR-160 for example) or you could get a VF-2 or VF-3 on it for probably close to the same machining possibilities and more rigidity.
12:13 we bought the umc 500ss last year september, and that is exactly what i am doing every week. the chip conveyor is not very well design. ☹️ really give us lot of problems when we are running production.
Having worked closely with 2 umc750ss machines without even watching this video I can bet you'd probably sell. They have so many problems tracking parts when using the multi axis functions. Sell them all and get some DMGs
Next thing to invest in is some good automation. CNC machines are the first step, but to maximize your lean potential, gotta get them robots going. And not the silly CRobots.
Seems to me there is one operation missing in the 5 axis. When do you machne the dovetail? This would add a vise, hard jaws and machining time. Nevertheless I agree 5 axis is far superior when machining complex parts.
We havent seen the rigidity issues in finishing other than the head does sag and the table does dip, but have seen the head bounce in the x during heavy roughing.
The new UMC’s are just not great.... where the first was awesome imo. Chip conveyors suck now, I’ve seen people with M19 tool orientation problems with tool changes, G187 just not working... at all! Etc etc.
When reading your comment i was looking for the Read more to click on, LOL. Seems there is a fairly long list of Don't Likes for a HAAS 5 Axis. I did not have huge expectations they would be in the Great Machine category. Even Jay woke up at one point and brought Doosan Lathe.
Touch screen are nice if you can touch the icon faster then you can used the arrow keys some machines its really nice other's its kinda afterthought. Also traveling colom machines are good machines it's mostly who is making the machine.
Hass biggest problem is the size of the ways. The ways on my 2010 sl30 compared to my 2002 Mazak qt30 is massive. On the Mazak, they are like 3 times the size of the sl30..
That's why most 5 axis machines are a lot bigger for same table size. The y axis ways would extend to the sides of the table rather than be in the back of the table. First generation umc750 had exactly same problem, lacking y axis rigidity. A bit disappointing that they stil havent been able to cure it. Same time most of the competitors cost atleast twice as much so...
There has been some talk of a New Generation HAAS 5 axis model series, which has fixed the problems you mentioned. But that doesn't do much for the Die Hards who try to support a local manufacturer and purchased there machines pre New Gen series ????
yea i would stil go for a DMG if i wanted a 5 axis machine. (DMU 50 3gen, Evolution ect ect) yes more expansive but .... but with the stuf we make .... we also need the better build quality
That would end up making the problem worse. Part of design is figuring out how your customers are going to use the product. If it tilted as you suggest, customers would program with the table facing the front of the machine so they can see the work happening which means the spindle carrier would always be at greatest extension. We have a DMU 65 with a table that swings 90 deg from what the UMC does. Our programmers always have the workpiece facing the window. Fortunately the DMU is ridiculously beefy so this doesn't matter.
We are now evaluating a 5axis to buy. Looking at Mazak, DMG Doosan Okuma and Hass. The price of Hass is just so much lower, but on paper the performance look the same. What is your take?
Hey Jay! How is the Haas lathe coming along? Are you planning to do a comparison against Doosan? Trying to decide what lathe to get...already have a Haas Mini Mill 2 so kind of leaning towards the Haas option. Can you offer any advice? Thanks, Vlad from Omelko Research
We have a umc750, umc500, a vf4 w/trt210 and 5 vf2 trt160’s. The trt’s are pretty damn rigid but where the umc’s shine is bigger parts that won’t fit in the trt window, also if we need more 3 axis only, we can throw a vice or big fixture plate on top of the platter. But I haven’t noticed any accuracy issues with the umc’s but most part familys for those machines are +/- .005
The unwanted finger touching the screen is not something i had considered. It is obvious when you think about. My concern with Touch Screens is wet hands with tiny little metal chips on your fingers ???? I am curious how long before it becomes permanently scratched. Unfortunately it is becoming common place with most major machine builders.
The glass on all of our machines is pretty tough and we haven't noticed any scratches. Newer displays have an anti-reflective coating that would most likely be the first thing to go, but so far all of our displays are like-new.
@@rssilks the main reason is the rigidity while using long-reach toolholders. And also I consider that utilizing dual-contact is more suitable for 15.000 rpms as we are doing many surfacing jobs (however, thats in theory :) )
The UMC-500 is definitely NOT the machine for surfacing. The rigidity won't get any better with an hsk spindle because the mechanism the spindle rides on has too much potential for tolerance stack up error. The VM series is much more rigid, heavy and appropriate for that type of machining.
@@PiersonWorkholding thanks for the answer. We are doing some fancy-style parts for food packing industry from aluminum so there is no hard roughing. We just need it to provide us with an excellent surface finish while 3d countouring on 15k RPM with long toolholders. For example, i have a brand new VF2SS and i really DO NOT like the surface finish it gives us on its 12.000 rpm even on a lowest feedrates possible (all toolhoolders are new too and well balanced), but it gives a perfect finish while running 8000-9000 rpms
I think your explanation of the climb vs conventional cutting is somewhat accurate, the reason the machine holds tolerance better in conv cut is there is more load on the cutter and axis, if you tried this with more stock left on the profile you wouldn’t get the same results, your finish would be worse than with climb cutting. Have you ever used a manual mill, try it out with climb vs conv
I didn't completely agree with how you talked about the climb vs. conv argument, and especially the chip thinning part at 22:38 I do understand what you meant, but you are using the term 'thinning the chip', which sounds a lot like chip thinning and might confuse people. I do understand that you get more chatter because of the harsher cut with climb milling in a less rigid machine, but you have to be aware of the rubbing and chip thinning factor with conventional milling. I'm sure you are aware of it, but people might have more rubbing and tool wear if they conventional cut at too low of a feedrate or DOC compared to the same cut but climb milling. Thank you for the great video anyway, it's great to have such an insight in a pro environment.
Wow, my major in college wasn't even ME, but I can see that this is a seriously flawed design. Stacking the Z axis, onto the Y axis, onto the X axis creates a system of cantilevers that at their extreme limits means the cutting tool is as far as 32 inches away from the ridgid frame of the machine. I am surprised that HAAS okayed the design of this in the early stages of manufacture. The same exact functionality is available in the standard VMC format with the 4th and 5th axes mounted on the table. And that is inherently more ridgid, and resistant to resonant vibration.

Conventional cutting requires a VERY sharp tool, but I sure like the final result.
The cut material accumulates at the front and they will be re-cut which causes surface finish not good , will this happen as well?

Hello people of yt, I am considering buying the same machine, my question is does it needs to be bolted down to the floor?
Do you have any experience with the TRT160 or TRT210 on a VF that you can compare against the stiffness the UMC 500?
No but any rotary on a VF series is sure to be more rigid. The B and C axis platters are not the weak link.
We have a umc750, umc500, a vf4 w/trt210 and 5 vf2 trt160’s. The trt’s are pretty damn rigid but where the umc’s shine is bigger parts that won’t fit in the trt window, also if we need more 3 axis only, we can throw a vice or big fixture plate on top of the platter. But I haven’t noticed any accuracy issues with the umc’s but most part familys for those machines are +/- .005
our chip conveyor always glogs too. and it trickles the coolant out the the slots causing it leak all over the floor...

How’s the Through spindle coolant at tool change after drilling ? We get explosion of coolant.
That's a purge of the through coolant line with air at the tool change.
@@PiersonWorkholding do you think it’s safe we have the HSK spindle and first time using through coolant for everyone here .
Basically 2 ops*** on simple square parts...
That is the dream that doesnt really work on real complex parts. :)
I didn't completely agree with how you talked about the climb vs. conv argument, and especially the chip thinning part at 22:38
I do understand what you meant, but you are using the term 'thinning the chip', which sounds a lot like chip thinning and might confuse people.
I do understand that you get more chatter because of the harsher cut with climb milling in a less rigid machine, but you have to be aware of the rubbing and chip thinning factor with conventional milling.
I'm sure you are aware of it, but people might have more rubbing and tool wear if they conventional cut at too low of a feedrate or DOC compared to the same cut but climb milling.
Thank you for the great video anyway, it's great to have such an insight in a pro environment.
Where do you get those paper towel holders?

Titan said it. "Haas are throwaway, light duty"
titan sells his opinions to the highest bidder

@@SuperAWaC Yep!
Right , all about helping Cali folks get jobs in the industry till he picked up and moved to Texas.
It's all fun and games until the CNC machine can't do the same thing twice.
Haas better then a mazak ?
Step up to a Okuma
No way, on that small part, 1.35in, that the dimensional discrepancy is axis deflection. Very disturbing.
sell it to me!!!!!! and then take me on as your apprentice plz. = )
Jog handles are INVALUABLE for indicating parts or stock in.
Wow, my major in college wasn't even ME, but I can see that this is a seriously flawed design. Stacking the Z axis, onto the Y axis, onto the X axis creates a system of cantilevers that at their extreme limits means the cutting tool is as far as 32 inches away from the ridgid frame of the machine. I am surprised that HAAS okayed the design of this in the early stages of manufacture. The same exact functionality is available in the standard VMC format with the 4th and 5th axes mounted on the table. And that is inherently more ridgid, and resistant to resonant vibration.
paint doesent stik to stainless
It's not stainless and if it were, it wouldn't need paint.
Or, would you buy another one
2:30 - minor slip of the tongue 😀
dude ill give ya 500 bucks cash right now
Fuck you're generous!
