Note :
(1) X and Z axes actual cutting diameter will change when equipped with different turrets.
(2) Specifications are subject to change without notice for improvement
* Precision tapered roller bearings are equipped on the spindle and the quill.
* The quill is heat treated and precisely ground.
* Internal taper of quill to suit MT#6 dead center or live centre.
* Turcite B anti friction material is applied on cross slide and carriage for reduce friction.
* X and Z axis ballscrews are protected by covers to prevent ingress of swarf / chips and coolant.
