Abstract: The upright and inverted lathe machine is a new type of machine tool born in line with the trend of the automation era, which can achieve efficient processing of disc-shaped parts. Combined with the characteristics of the vertical and horizontal turning lathe machine, taking the brake disc part as a typical application example, through the research on the processing technology of the brake disc workpiece, an automated production line of the vertical and horizontal turning lathe was established, and the fixture and elastic positioning mechanism matched with the inverted vertical spindle were designed, and the clamping and processing mechanism of the upright vertical spindle was designed. It has certain advantages in production line layout, processing accuracy, production capacity and processing efficiency, compared and analyzed with the traditional automatic production line. Practice has proved that the application scheme of this production line has a good effect on the actual operation process, and can ensure that the vertical and horizontal turning lathe production line meets the user's requirements in terms of production efficiency and processing accuracy.
