Pipe thread lathes generally have a large through-hole on the spindle box, and the workpiece passes through the through-hole and is clamped by two chucks located at both ends of the spindle for rotary motion. There are generally two ways to feed the cutting tool: one is to drive the slide plate and tool holder located in front of the bed by the screw, which is the same as that of a regular lathe; Another method is to use a flat comb blade external thread cutting head (see automatic opening and closing thread cutting head) located on the slide plate in the center of the bed to cut into the workpiece and move forward accordingly. Some machine tools for processing long pipes also come with workpiece support devices, such as center frames, follower frames, rear supports, etc.

Main Features

1. Versatility
   A pipe thread lathe can not only process internal and external threads of pipes but can also function as a conventional lathe, capable of machining shafts, discs, and other workpieces for external diameters, internal holes, and end faces.
2. Efficient Processing
   When using a CNC pipe thread lathe, various straight pipes and tapered pipes can be machined efficiently, making it suitable for pipe fittings, rods, casings, and various types of pipelines.
3. Automation and Precision
   Modern CNC pipe thread lathes have a high degree of automation, providing high-precision machining results. They are easy to operate and have a wide range of applications.
4. Structural Design
   Many pipe thread lathes feature a large-span headstock structure that enhances the rigidity of the machine and improves the stability and efficiency of the spindle.
5. Low Noise and High Speed
   These machines typically possess high spindle speeds and a wide speed adjustment range while operating with low noise levels, which is an important advantage for long working hours.
6. Wear Resistance Treatment
   The machined workpieces often undergo nitriding treatment to improve their surface hardness and wear resistance, ensuring durability during use.
