Feeding device of numerically controlled lathe

The invention relates to a feeding device for a numerically controlled lathe. The main body of the lathe is a saddle. A cross feed device and a longitudinal feed device are arranged on the upper and lower parts of the saddle respectively. The upper surface of a lathe bed and rails arranged on the upper surface of the lathe bed are arranged horizontally. The part, connected with the lathe bed, of lower part of the saddle is correspondingly arranged horizontally. The side, facing a processed workpiece, of the upper part of the saddle is provided with an inclined face. The inclined face is provided with the cross feed device. The inclined saddle with small size and light weight is easy to process, and the lathe bed has good manufacturability and is easy to process and install.
