Flange face lathe, also known as big head lathe, Plate lathe, Pit lathe, Flange lathe. The base rail adopts a rectangular structure, with a large span, good rigidity, and is suitable for low-speed heavy-load cutting. The structure of the floor lathe adopts a bed rail with the headstock spindle perpendicular to the movement of the pallet. The headstock and the transverse bed are connected on the same base. The base is a mountain-shaped guide structure, and the lateral movement of the pallet can be manually adjusted. This machine tool has a large load-bearing capacity, strong rigidity, beautiful appearance, and convenient operation. It can turn the inner and outer cylindrical surfaces, end faces, arcs and other forming surfaces of various parts. It is an ideal equipment for processing various wheel and tire molds and large flat disc and ring parts. Floor lathes are mainly used for turning heavy machinery parts with larger diameters, such as tire molds, large-diameter flange tube sheets, turbine accessories, heads, etc., and are widely used in the processing and manufacturing of petrochemical, heavy machinery, automobile manufacturing, mining railway equipment and aviation parts.
