General advice needed

Hi guys

Yes julian that is exactly what i meant,

I have managed to repair this by removing the handwheel and conical nut and also the small aliminum chip gaurd from there i was able to push the table back as it was no longer connected to the leadscrew, and there is was the screws on the bush were loose so re-tightened them with some loctite and a spring washer, then had to mill out a bit of the bottom of the chip gaurd

I put everything back together and adjusted the cone nut as you guys have suggested and it a great deal better so hopefully be able to starting to use it soon

The next thing i was maybe going to look at would be how to make the central column a bit stiffer, i have a bit of vibration was thinking of clamping it back to the wall?

It's probably better to try and locate the source of vibration and cure it rather than simply mask it. As a starter does it occur when the mill is runninh but not cutting, or only when the mill is cutting?

the vibration seems to be comming when im cutting, i can feel it throughthe leadscrews?

Ok, so we've established that the vibration is to do with the cutting process. The next step is to see if it is correlated with anything in particular. Say a specific spindle speed, cutter size or type, feedrate and so on? Is anything loose, like the gibs?

I was renting workshop space off a machine tool supplier in the early 80's he had a turret mill?(tiawainese) vibrating he asked me to fix it ,I found the stepped pullies were machined off centre
