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

I was teaching a student how to use our haas and the first thing she did was try to touch the screen.

[@kchigley5309]

@@SuperAWaC But having only a touch screen like DMG Celos or Mazak Smooth is absolutely awful. Source: we have 4 machines with Celos and 3 with Smooth. Heindenhain, Siemens and now Haas got it right by combining both touch screen and physical buttons.

Conventional cutting requires a VERY sharp tool, but I sure like the final result.

[@ray-charc3131]

The cut material accumulates at the front and they will be re-cut which causes surface finish not good , will this happen as well?

[@paulmace7910]

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.

[@sethhughes2163]

[@salvadorebertolone]

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.

Good review. For me, there are too many minuses at the UMC 500 No options for lifting with a crane when changing fixture or large items UMC 500 Starting price in 90,396 € With only 8100 rpm SPINDLE WITH 15,000 RPM + 9,036 € OIL SKIMER FOR COOLING TANK + 396 € AIR FLOW THROUGH TOOLS + 876 € CONVEYOR BELT FOR BELT TYPE CHIPS, UMC + 5,276 € COOLING THROUGH SPINDLE + € 4,876 Total = € 110,856 I mean you get too little for your money for that quality.

[@Awfultyming]

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

[@jeffnunez4766]

Thanks for sharing I know this will help someone trying to decide whether or not to buy an UMC. I am a fan of Haas for all the education they provide and ease of use. but would never spend $130K+ for an Haas UMC and definitely will stay away from the EC Horizontals, a friend bought 2 of these and had to ask Haas to take them back after fighting with them for 6 months about not being able to hold the tolerances he was holding on his 25 year old Toyoda. Yes is more about the machinist but Haas need to step up their game in terms of quality since there are already a few Made in Taiwan machines with similar price point and better quality. BTW they still will not release their machines accuracy and repeatability specs like most manufacturers do.

[@mirsidorov5112]

What other brands have better tolerances? Looking to buy a few cnc and still deciding.

[@gcbefree68]

You should try HERMLE. But i think its much more expensive...

[@SuperAWaC]

[@rickvm1202]

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.

[@PiersonWorkholding]

That's exactly what we did later. We added a TRT210 to our VF4 and love it. Here's a video about it: kzbin.info/www/bejne/eWaQq4qpp5Kti5I

[@punkdudex69]

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.

[@Andrey222ful]

Thanks for telling the recipe, would be great to know how do you work with extended tools, I mean like 10 x D end mill and avoid chater?

[@punkdudex69]

@@Andrey222ful To me, that is the fun part of being a machinist. Depending on each application and process, tool length rigidity is a creative process. As its said there's multiple ways to skin a cat. There are many variables to consider in that scenario (machine , tools, gd&t, tool path, costs, risks, etc.) . In any case, building a strategy to achieve machining challenges comes down to trial and error (hopefully minimizing costly mishaps). That's kinda the beauty of this craft and the wisdom that can be obtained.

Given your comments about rigidity on the UMC, would you recommend adding a TRT210 unit to a VF2 instead?

[@PiersonWorkholding]

Yes! In fact, our next video is all about that.

[@heheeeeeeeeeeee]

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...

[@weldmachine]

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 ????

[@Eduard90_]

How do you handle the problem with the flooding chips, specially if you mill plastic ? The chip conveyer is a nightmare.

[@bcbloc02]

Guess they should have mounted the rotator 90deg the other way so it leaned the work in towards the spindle.

[@kchigley5309]

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.

[@Cthowell91]

our chip conveyor always glogs too. and it trickles the coolant out the the slots causing it leak all over the floor...

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.

[@joep1253]

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

Thank you for a review! I'm looking into buying a UMC 500 but with HSK spindle option. Do you know if Haas's HSK spindles are reliable and rigid?

[@rssilks]

Hi, is there any particular reason you are looking at the HSK spindle?

[@ICON.Engineering_]

@@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 :) )

[@PiersonWorkholding]

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.

[@ICON.Engineering_]

@@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 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.

[@davyjones5890]

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.
