I wondered this also in the video, or did they make an oddball for Haas with 40mm? I looked on parts site and what I assume is the old UMC-750 is 35mm. 45mm rails and hsk-a63 spindle could potentially make a pretty rigid machine, I would think."We upgraded to the next size linear guideways."
So, the new machines now have 45mm linear guides? Because 35mm is the standard for machines of that size...
45mm rails are definitely the way to go for maximum rigidity and cutting performance in that size machine!
Or, did the previous versions use 25mm rails (really wimpy), and now they've upgraded to 35mm??
At a minimum, they should have cast some angled reinforcement into the truck mounting areas there on the bottom of the column...
45 and now 55
Knowing Haas, I highly doubt they would go to 55mm guideways on that size machine.
55mm’s are huge, and normally used on huge machines.
The guideways in the video looked more like 35mm to me, if so his claim they went to the “next bigger size” is either false, or the previous generation had 25mm guideways (highly doubtful as those are normally used only on tiny metalworking machines, and material handling equipment.)
I have said this forever on roller vs ball linear ways, how much more would it really cost? Haas seem to go on the small side and use ball ways. Would be interesting to hear their justification on this.Dumb-ass question, but why wouldn't MTBs just go big on everything? The marginal cost between 45mm guide ways and 35mm guide ways should (theoretically) be quite small as a portion of the overall machine cost. Isn't bigger == better?
Y & Z measure 35mm on my '17 750SS.

[/I]Gene is missing a lot of market potential by not building a "world-class" line of Haas machines, and thus dancing with the big boys of Asia...
Orange Vise's good point notwithstanding, anybody ever out there ever tried to refurb a Haas machine with new rails? The sizing is mostly standard, no reason you couldn't swap them out with a set of high precision preloaded roller ways. Curious how that'd affect the machine.
I agree that if they build more solid and precise machines for more $ "Peeps" would buy them , home team and user friendliness an all that. + support that's actually "There".
I'm a firm believer in not venturing too far out of one's wheelhouse.
I'm a firm believer in not venturing too far out of one's wheelhouse. While I have no doubt Haas would sell plenty of top end machines if they made them, I have no idea if it would be a profitable venture. More importantly, I'm not sure how it would affect the brand.
Haas has successfully carved out and dominated the value and ease-of-use sector of the market. I think if they try to venture into other areas, e.g. top shelf, they run the risk of losing ground they've already gained. End of the day, I think the financial security of market sector dominance is more valuable than just about any other financial metric.
