Introduction
CK43 series lathe is designed for automotive industry to machine crank connecting necks. crank connecting necks semi-finish or finish process via eccentric jigs driven by the right and the left headstocks. This lathe consists of bed, left headstock, right headstock, left jig, right jig, slide, turret (with a12-station indexing disk), NC control system, electric system, cooling system, lubrication system and guards. Horizontal machine bed and base are made with high-grade cast, high rigidity, wide rectangular hardened guide ways. Machine saddle and cross slide are made with high-grade case, the guideways are turcited and with less dynamic and static friction. The spindle is arranged by FAG large diameter precision angular contact bi-directional thrust ball bearings and double row cylindrical roller bearings, which have good stiffness. The X and Z axis ball screw adopts pre-stretched nut structure, and the supporting bearing adopts Japanese NSK angular contact special bearing, which greatly improves the stiffness and thermal deformation resistance of the screw, and greatly improves the feed accuracy. The turret adopts 12-positionhorizontal electric turret of Italian DM Company.
