Background

The vertical lathe is different from the common lathe in that the main shaft of the vertical lathe is vertical, which is equivalent to the common lathe being vertically erected. The workbench is in a horizontal position, so that the machine is suitable for processing heavy parts with large diameter and short length. The precise numerical control vertical lathe drives the ball screw to drive by the stepping motor, and the precision is mainly ensured by the machine tool and a program because the ball screw can have interference magnitude and has no transmission clearance. The automatic measurement can be carried out during the machining process, and errors caused by tool wear and other reasons can be automatically compensated. Therefore, the processing quality is good and the precision is stable. And parts which are complex in shape and difficult to machine on a common lathe can be turned by a programming method. The precision numerically controlled vertical lathe is suitable for machining medium and small disc and cover parts, and has high strength cast iron base and upright post, vertical structure with high stability and high shock resistance, convenient clamping and small occupied area. In modern life, automobiles are more and more popular, and the increase of the automobiles promotes the increase of the demand of wheel hubs. The precise numerically controlled vertical lathe is especially suitable for machining wheel hub.
