Hi all.
Haven't posted much on the forum in the last 5 years.
I have a Novakon Torus Pro, installed brand new in 2019. The y-axis has developed some backlash, which is due to the axial movement of the feedscrew (visual observation). So the ballscrew appears to be ok, it is likely the bearings on either end of the screw that need work, replace / upgrade
I am very used to working on my own equipment; now considering upgrading to a larger machine, and one that is more heavy duty (A Haas TM-2p)
Thing is, I can't figure out how to replace the t-axis bearings, don't know how to remove the y-axis feedscrew, or back off the feedscrew from the bearing block to remove the bearing block for working on it.
With help, we were unable to unscrew the 'castle' nut on the y-axis feedscrew bearing, closest to the stepper motor end. Did loosen the 2 locking set screws (one of which bounced off into the chip pan, never to be seen again)
So, now, do i spend more time fussing with it, or sell it as is, and buy a new machine?
Machine is still useable, but 0.017" backlash on the y-axis, I don't feel comfortable running it like that.
