Introduction of floor boring and milling machine

In practical use, the workload of milling is usually greater than boring, so it is also called floor milling and boring machine, which is mainly used in heavy machinery manufacturing enterprises. (see color map)

The floor boring and milling machine (see figure) has no movable table, and the workpiece is fixed on the floor platform, which is suitable for processing workpieces with large size and weight. The headstock moves vertically on the column, and the column moves horizontally or only horizontally on the lathe bed. There is a ram in the headstock that can expand and contract with the milling shaft. Its cross-sectional shapes are rectangular, square and polygonal, most of which are rectangular. The indenter is large in size and high in rigidity. The ram is used to support the spindle and install accessories, and is suitable for powerful milling, which can expand the process scope and improve the machining accuracy. The boring shaft is installed in the milling shaft, which can be extended and fed independently. The large floor boring and milling machine is also equipped with a high-speed spindle for drilling. The machine tool is equipped with a platform, a turntable, a rear column, a flat turntable, a vertical milling head and a universal milling head.
