MEGABORE CNC LATHE 45" SWING OVER BED

Megabore is the start of our extra heavy duty CNC Lathes with a 2 shear bed. Described here the BN-45 (45"swing) This model is also available with 50"and 60" swing. Features * One piece bed, floor type casting. * Alloy steel spindle with opposed taper roller bearings. * All gears in the headstock are hardened and precisely ground. * Automatic ranges of spindle speed through pneumatic gear shift. * Spindle speed ranges are automatically changed by M code. * Infinitely variable speed are commanded by S code. * Tool change are commanded by T code. * Auto lubrication system is equipped for headstock, carriage, and cross-slide. * 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. Photos show some variations of the BN-BNC range.
