Are Haas mills any good? It depends on what your doing. It's as simple
as that. They sell an awful lot of them, so they must be doing
The more appropriate question might be how *long* are they any good. The thing I think a lot of small shops don't consider in the purchasing equation is the total cost of the machine over the ownership life.
Sure HAAS will have plenty of parts in stock, and the reason for that is not because they value the customer and out of the goodness of thier heart they keep a few million dollars worth of parts on hand just in case you need them. They have that inventory because they sell the parts.
With machine tools, you either pay up front, or you pay later, or you pay over time, but you are going to pay. The problem with paying later or paying over time is that just like a loan, it costs you more. You lose machine time that you could have used to make parts and you lose the money you pay the tech to come fix it, or even if you fix it yourself, you lose the unproductive labor you have in that. If you keep oft-failing parts on the shelf at your shop, you are out the money you have tied up in spare parts inventory, which you could have invested in more profitable avenues.
You have to look at the overall, long-term picture when deciding on a machine tool.
Yup. We've needed a few parts here and there. We have 7 Haas VMCs. 2 of 'em are 9 1/2 years old. And will still hold .0007" positioning. And this is after 9 years of cutting P20, H13, S7, A2, etc... All mold making stuff. They've been good to us. Just gotta know how to maintain them, and not over do it on things such as depth of cuts, or over loading the tables. They will blow out servo amps if overloaded.
