Hi,
I have got a cnc lathe slant bed of jyoti fanuc oi tf controller 2 axis.. the issue which I am facing is that few weeks back one of my employee crashed the machine and I have got the engineers of the company and got the allignments fixed of head (spindle) -.110 in the length of 200mm, and z -.300 under 0.20... But the issue is still it gives taper of +0.030 in the length of 45 mm.... Can't think of what could be the issue as it doesn't even makes any sound of breakdown....if I use the maximum boring bar which is 40 mm for the machine there's no taper or misalignment on the use of below 40 boring bars like 32 or 25 on smaller Id workpieces. It shows taper of 0.030 on 45 mm length. Can anyone help don't know what could be the issue..
As the company service people of jyoti isn't much of help because on id theres no taper just on id and using boring bar holders below 40... Theres no load on any motor or spindle
