Got my new G0729 milling machine a couple of weeks ago. The front nut & bolt that fastens the turret to the main casting is locked solid . I was told I would have to cut it off. The only way I can see is to chisel it off off because of the limitted access around it..There's no way I'm going to whale away on it with a hammer and chisel. Besides I don't have enough head room to lift off , so it is going to stay that way depriving me of the ability to rotate the turret.
When I tried to tilt the head in order to gain better wrench acces to the bolt in question the head bots jammed in the horizontal position when they reached the access portion of the circular T slot . I had to get a couple of guys to help me take it apart and re-orient the bolts.
The bolts seccuring the power feed casting bracket to the table were loose. Tapped holes in the table turned out to be stripped. I tapped the holes deeper in the table and counterbored the holes in the support casting deeper to fix he problem.
The Y axis gib is tight on one end and loose on the other. Also will have to live with that.
There is a drag when moving the X axis even with the gib totally loosened. Looks like a bind between the lead screw and the nut this has resulted in a lack of repeatability. The workaround is to lock the table every time I need to get rid of the backlash Being a geezer working alone I'm not about to take the whole saddle & table slide apart. Another "live with it"situation. Another posssible workaround would be to add a DRO. Expensive. Tech support said "yep that would cost you a lot of money".
Besides the offer to send me new gibs which wouldn't have fixed anything anyway, tech support basically provided only a sympathetic ear.
When I had a problem tramming the head in the Y direction on My Rung Fu mill which I bought a couple of years ago from Enco I shimmed it as a fix. Enco sent me a shim pack and gave me a $200 rebate for my trouble.
Ship it back you say? It cost me $500 to get it moved to my basement. It would cost more then that to get it back up the stairs. Then there is re-crating and shipping. All on my own hook no doubt. Nope I'm stuck with it. The machine is usable just not the way it should be. I have had enough experience with Asian machinery to know that they require some tweaking. This one goes way beyond.
