well emax is soft so idk what happened there.
but really, you can't go wrong buying literally anything for zirconia wax and plastic. that manufacturing is so easy on the machine you can probably build your own, using 4 stepper motors and some duct tape and come out with a fine product.
robustness of a machine comes with its ability to produce at maximum power. not minimum power.
what is my opinion of a 51d? i can't care. same trite bs dumbed down mill as vhf and imes.
i'm not trying to downplay the gravitas of the thread; by all means it is of course worth as much as a new car and you should want to do great things with your machine and not run into difficulties. but that does not mean anything in the grand scheme; you will have to buy a new machine when you grow, a new machine when you expect to do some new material like PEKK or PEEK, and a new machine when the old one breaks down as it inevitably will. its not bulletproof.
so do you want to run the crap our of a 23k$ mill and make a bunch of money in zirconia, or do you want to spend 5x that amount and get a machine that should last you 5x as long, and be already equipped to cut these new things, and ones that have yet to be released ?
its a financial decision as much as it is a practical decision. but ive long maintained that buying a cheap mill"to get started" is not worth it. far better to buy a stronger more durable machine and grow to your hearts content.
did you know you can buy a 5 axis haas with 10 horsepower for as little as 45k USD brand new fresh from the factory? add the necessary ancillary products like extra M codes and a coolant tank and for as little as 74k you've got a competitor to imes's 650 offering which im not convinced is worth the 250k pricetag.
mind you, getting cam support will not be easy. worth it to hire an actual machinist instead of d1ck around trying to get a dental tech to cut your parts.
so 74k x2 lol
its overkill for zirconia. but again that sh1t's simple man. if you can't do it blindfolded after 2 months, with no errors, i gotta question how much you know about what you are really doing.
its so easy that you can stagnate as a human being sitting there pressing Go and not using the organ between your ears. so i resent zirconia and all the support it has gotten in dental. thats why i talk so much trash about it.
