Pipe thread lathe
Pipe thread lathe, also known as pipe thread lathe, consists of three series: one is a horizontal lathe with a diameter of Φ400-1600 mm and a length of 750-10000 mm, and the other is a pipe thread lathe with a spindle diameter of Φ130-440 mm. Third is a variety of large-hole lathes, large-head lathes, special machine tools, etc. with a spindle diameter of Φ130-440 mm. Products are widely used in mechanical manufacturing, petroleum, chemical, coal, geological exploration, urban water supply and drainage industries.

Products are widely used in mechanical manufacturing, petroleum, chemical, coal, geological exploration, urban water supply and drainage industries.
The pipe thread lathe generally has a large through hole on the headstock, and the workpiece is passed through the through hole and clamped by two chucks at both ends of the spindle for the rotary motion. There are two ways to feed the tool: one is similar to a conventional lathe that is driven by a screw to move the slide and the knife holder in front of the bed; the other is a flat comb that is located on the slide in the center of the bed. The external thread cutting head (see automatic opening and closing thread cutting head) cuts into the workpiece and is moved forward. Some machines that process long tubes also have workpiece support. The pipe thread lathe has been partially digitally controlled. Each time the workpiece rotates by 1 revolution, the tool moves uniformly according to the number of feed pulses corresponding to the distance of the selected pitch, which is convenient for machining the taper thread, changing the pitch and correcting the pitch error. These machines are capable of machining workpieces up to 15 meters in length and up to 400 mm in diameter.
