Hi, Well I got the chuck and after a few problems I fitted it, It has reduced my vibration problem about 50%. Now the vibration is just the tool and not the whole machine.
I have made a video which is about 10 meg and can be downloaded here,
www.jtechdesign.co.uk/orac/lathe3.mpg Please note the video and sound my not match exactly as I had to do them separately.
I've used different tools at different heights to the center and they all do the same to a lesser or greater degree, The only difference since I changed the chuck is the shoulder of the piece shows no chatter marks and looks well turned.
I'm starting to think that it may be something other than the machine it's self.
I have noticed that there is a delay before the retract from the cut allowing at least 5-10 revs of the spindle before retracting.
On my Boxford it retracts off the cut immediately
I'm wondering if, because the tool is just sitting there, it is just rubbing on the radius of the tool nose.
Why is there a delay between commands, I'm turning only using G1 and G0 commands.
Could it be that I'm using a 800mhz computer and it's just not quick enough?
Any idea's are welcome as I am almost at whits end.
Kind Regards
John
