As you should be able to see I've decided to change the layout of the servo motors, to get more operator space. I'll increase the crossslide table 12mm in height to create space for an standard Bosch-Rexroth ballscrew with nut. The original nut was an very special made one, very low which passed the z-slide with only a paper between. Also my cross slide table where worn down due no seals, a "not that great" design from the factory.
And a complete Ajax lathe kit are just waiting along with a 7,5kW frequency inverter from ABB.
Left pic is original with x servo in fron and z at rear right. Right pic is redesigned with x servo at rear in swarf bin and z servo under the gearbox. Designed in SolidWorks 2005, but the low definition pictures does not show that much details. It would be nicer to post the CAD files trough eDrawing.
