Currently I run a 10 horse phase converter for all my equipment 3 mills, 2 lathes, 2 grinders, compressor, etc , do you think I would need to run a seperate converter for this machine? What materials does anyone cut on these and what type of tolerances are you holding, thanks again! So no phase converter is needed.
By running the machine on single phase, is there any loss in performance? I believe you loose about a third of your HP, and instant reverse as in with rigid tap are not possible. Now that info applied to my Fadal if I ran it single phase, I don't know if it is the same for that particular Haas model or not. IIRC, no performance loss - the spindle drive just has an oversized input stage, such that full current goes thru only two legs of the rectifier, instead of three. But, call Haas and check to be sure Join Date Jun Location titusville fl.
Simmah dahn nah! The Haas factory rep told me that a lot of toolroom machinists are intimidated by cnc mills. The "toolroom" mill is merely designed to get a cnc mill into a manual toolroom. Once the guys get over their fear of sheetmetal and no handles they are supposed to want a real machine. Those things look like junky little toys to me. I guess we should think of them as "training" mills.
Kind of like the "pull-ups" my 3yr old wears at night so he doesn't feel like he's wearing diapers. When outgrown they should be discarded.
Actually, at a place I used to work at, they had small mills that were 2 axis cnc knee mills. I guess you could call them toolrooom mills, since that's where they were located.
But, my bossed loved them for the purpose of training newbees on cnc's. Once they got the hang of controlling 2 axis', they then stepped up to a 3 axis.
Well I guess whether or not the TM-1 looks "junky" is a matter of your perspective If I bought a new Hermle or Mazak machine I would have to declare bankruptcy on the day it was delivered. Not to mention the fact that they dont fit through the windows or doors of my shop and that the flooring would not hold the weight.
Not to mention I have no idea where to start on such a machine. For me, the Haas has a steep enough learning curve. The professional machine shops I know here all have much bigger and "better" machines. They also have multiple workers who use the machines, sales depts, etc etc. It's a matter of scale. For the price in relation to the features it offers value , the TM-1 is an exceptional value for a segment of the market like myself for whom there are very few options.
I have had the TM-1 for 3 weeks, made my first salable parts the first week and have been milling parts from titanium and steel with very few problems since then. My production capacity has radically increased already and the tolerances have gone way way down and this is just the beginning.
I have already done 2 outside jobs for the stainless steel fabricator next door and it looks like he may easily have enough small jobs for me to pay for the machine. I did discover that putting the wrong numbered tool in the machine at a tool change is a bad idea unless you like watching carbide cutters break off, but I don't think even the most polite Japanese machine would prevent me from doing something stupid like misreading the moniter.
So I guess I'm trying to say that from my perspective, I'm looking up at the Haas machine and it looks great. You guys who are looking down, well your view is different.
