Sdgt-320d Double-Axle CNC Boring Lathe

SDGT-320D Double-Axle CNC Boring Lathe is a special equipment for the precision machining the cone hole and end face of the roller simultaneously, which is independently developed by Atoman Science and Technology Ltd., aiming at meeting the requirement of roller concentricity in gravure engraving and electric roller industries. It is uniquely designed according to the patent technology, with characteristics of high concentricity, high processing efficiency, easy operation and high reliability.
FeaturesAdopting two spindles of mechanical shaft and boring tool shaft to realize the synchronous precision machining of cone holes and end faces, with high accuracy, high efficiency and great capability.Natural granite bed with good thermal stability and vibration absorption.Equipped with the self-centering device of the roller, and the hotkey operation can be set through the macroprogram.It can also process the inner chamfer and outer chamfer, beside the cone hole and end face.
