Not having any gearbox machines I don't have an opinion but I do have a question. Isn't getting the 10k option with a gearbox machine a bit contradictory?

If you get one it will be interesting to see what the parasitic load of the gearbox is at 10k. In high range the drive is probably straight through but you still have a lot of gears whipping around in the oil.

No problems to note. They are proving dependable. Running a 4 inch face mill into a block of tool steel in rapid my give you some reason for concern but short of that I would not worry. Haas has done a lot of work on this and a few years ago introduced 30% larger gearset. There is a pressure switch to sense a loss of oil to the gearbox but I would recommend regualr oil changes and PM's.

On the other hand Haas is faster and of course is new!! the best solution is to buy top technology this way you are on step ahead from the competition but i don`t have the money for more those machines ... i don`t want to make the wrong decision here ... Anyway thank you for your advise!

The MV-40 is a really good machine. I have had the opportunity to work on a few. However replacement parts can be hard to find at times and if the part cannot be replaced with a standard off the shelf item you can wait as much as 6 weeks for a replacement.
We did have one that needed the Y axis ways rebuilt but for the most part they ran like a scared dog.

Money will be the deciding factor. Do what you can with what you have. Upgrade when you can.

Yeah, get your feet wet and you can get new machine later.

we have 13 fadals, 2 okk's and 1 mori.
we bought 2 vf3 ss with the small trunion for the same price as one of higher end machines (mori), i'm sure 2 machines out produce 1 most of the time.
for the jobs we are targeting the vf3 with trunions are working great.
since the vf3's are still new we have had no problems yet.
the work your planning on doing in the machine should drive your chioce.
my mori is 10 ears old and still holds .0002 with no problems, i doubt i'll have the same thing to say about the haas in ten years although it will hold it now.
bottom line will always be "you get what you pay for" but sometimes the cheaper item will work fine for now and you can upgrade after you make some money.

I work in a shop that has 6 brand new Koran made machines, 2 15 year old mori, 1 3 yr old hass. every Koran made machine has had it spindle replaced at least once before the warranty was up. There is even one machine that has had the spindle replaced 4 times two times after the warranty. The hass and mori has let to give us any of the same problems and we are able to run them allot harder. But if you are looking for a good throw away machine the Koran made ones are it.

Go With The Korean Made. I Just Bought Their New Tm1-p Machine And I Have Nothing But Big, Big Headache. Everyone I Talk To From Haas Agree That They Are Lacking Quality. Because They Are Trying To Maintain Their 1000 Machines A Month. Surely This Is Affecting Their Quality. My Next Machine Will Surely Be A Korean Or Taiwanese. These Countries Are Trying To Win Your Business So They Are Exceeding Their Quality And Service. Good Luck

What sort of problems have you had with your TM1-P?
