So I bought the Hardinge (and Herbert) lathes that Gary was selling a few months ago.
Fast forward and I have selected a controller, replacement AC Spindle (Im not going to fuss with the DC system) and AC Servos for the X and Y Axis from SZGH, inspired partially from JazzCNC's experience of them (and my own) as well as others such as Hood and other 'known' hobby folk.
So, stuff arrived today, I think I am fortunate, I'm hearing of other people stuff from China being cancelled due to C19, so I think I was lucky.
The replacement items is the 2 axis control system with their 'C' Panel, 2 x 750W Servo motors and a 7.5 KW Servo for the spindle. The spindle is 'down' on the DC motor's torque figures however not by much. Going any larger would have needed major physical work on the mounting whereas here, I should get away with a simple adaptor plate.
The spindle motor on its own weighs over 60 kg, a beast of a thing. I dont have 3 phase yet, they have told me it will run off single phase (reduced performance) however that is enough to get the machine running and working. 3 Phase will be sorted at a point.
