Jut to let you all know that I have had some issues with the KX1 CNC milling machine.
The spindle assembly had a run out of 0.002″ (two thousands of an inch) in the 2 morse taper bore, which doesn’t seem like much but when a drill or reamer is held in the spindle, the error is magnified. The result is unreliable dimensions and it is almost impossible to ‘tram’ or true up the Z axis. There should be zero runout.
So for the past couple of months I have been in touch with Arc euro trade to come to a satisfactory conclusion. One big problem was that the Arc Euro engineer who carried out repairs and diagnostics had been taken seriously ill, so they had nobody who they could call upon for an informed opinion. So I dismantled the spindle assembly and sent it back to Arc for repair (see photo). It was sent back worse than it went! So it went back again! I think the error is a combination of below standard bearings and the spindle housing machined out of true.
It is now 16 June 2017 and I am waiting on a brand new spindle assembly from Sieg in China. Hopefully this will solve the problem.
I hope to produce something soon!
