Overview of pipe thread lathe machine

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, and three It is a variety of large hole lathes, big head lathes, special machine tools with a spindle diameter of Φ130-440 mm. The products are widely used in mechanical processing in machinery manufacturing, petroleum, chemical, coal, geological exploration, urban water supply and drainage and other industries.

Pipe thread lathes generally have a larger through hole in the spindle box. After the workpiece passes through the through hole, it is clamped by two chucks located at both ends of the spindle for rotary motion. There are generally two ways to feed the tool: one is similar to an ordinary lathe, which is realized by a screw driving the slide plate and the knife holder in front of the bed; the other is a flat comb knife located on the slide plate 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 realized as it moves forward. Some machine tools for processing long tubes are also equipped with workpiece support devices. Pipe thread lathes have been partially digitally controlled. Every time the workpiece rotates one revolution, the tool moves evenly according to the number of feed pulses, which is equivalent to the selected pitch. This is very convenient for processing taper threads, replacing the pitch and correcting the pitch error. This type of machine tool can process workpieces up to 15 meters in length and up to 400 mm in diameter.
