titan machinery milling machine defect
Posted: Thu Apr 18, 2019 11:16 am
First of all hello to everyone, as I am new to this forum.
So I joined mostly to get some advice regarding the defect of a table top mill and drill from titan machinery that I recently purchased new.
The model of the machine is 20 LV it has a 700 by 180 mm table, morse 2 taper and a 600w dc motor. Its pretty much the same as the ones from other companys, like optimum, quantum, holzzman...
So I got the machine home yesterday and realised that the head can not tilt to horizontal position as the cable is in the way; it gets severly pinched past the 45 degree mark, that does not concern me as it is easily fixable. But when I was fiddling with the head I noticed some scratches on the surface of the vertical slide, so I removed the mill head and found what to me seems as horrific damage. Some one has grinded all the way around the pivot around which the head rotates, and to me it seems that it has been done with an angle grinder or a similar tool. There are gouges and cuts all over, and most of the nicely machined surface upon which the head rests is, in my opinion destroyed.
Why or by whom has this butchering been done puzzles me but after much thinking I have theory. On the pivot there is a machined grove around the middle point; I can not see the reason for it, and it also appears that the person was trying and somewhat did cut a grove in the bottom corner of the pivot, basically a clearance groove, and destroyed the surfaces around it in the process. Other theory is that it has been done to remove rust, as I have seen marks of what appears to be scotch brite on the edges of the table and some other places and it seems to me it was done to remove rust.
Anyway I am new to machining, I have the mini lathe which I bought used for awhile now And I am very pleased with it, especially considering the price, its by no means perfect, but I acctualy think it is well made (except the finishing touches and tunning, which i dont mind doing myself) The only thing I dislike is the poor design or placement of the gibs, they should be on the opposite side and it would make a world off difference for the better.
So I was rather confident purchasing a chinese mill after good impressions with the mini lathe and a used one at that.
I contacted the merchant regarding this defect but no response so far.
English is not my first language and machining stuff is still new to me; so if anything is incomprehensible, just ask and I will try to explain better.
I have attached a couple of photos of the damage I am talking about.
My questions for you are:
Is this a common thing and was I just really lucky with my mini lathe, or unlucky with the mill? Or both?
Is it reasonable for me to demand a refund or another defectless machine from the merchant?
How much will this damage affect the performance of the machine if at all? And in what way?
Am I possibly just nitpicking here? (I honestly believe I am not)
What would you do in my situation? How would you deal with the merchant?
Thank you for your time and help.
Cheers.
