Re: YCM CNC Machines
I once was a probationary sales rep for YCM, I had to do a lot of research to answer questions and from what I can tell the servomotors, ballscrews and ballrails are on par with any mazak, the castings are made in Taiwan, not mainland China and the larger machines with boxed slideways are coated with mehanite on the sliding surfaces.
There were 3 specifications of controller, a basic meldas, a fagor like mid range and a fanuc full specification.
I don't recall the the spindle problem, I heard of that issue with hartford from water breaching the seals when really blasting the coolant.
The Haas has some really nice features and it's own flavour of control, I would be willing to bet that the ballscrews, ballrails and servos all came from the same source as YCM, I could be wrong.
If you can afford to buy Haas and live in the USA then spend the extra coin and buy your kids a job, otherwise YCM is a good taiwanese brand I'd recommend.
Wisdom results from foolishness!
