pipe thread lathe is specially developed by our company for the processing of AP pipe threads in the oilfield industry.The machine tool has a large spindle through-hole and a double chuck clamping structure on the front and back.It is suitable for all kinds of long pipe cylindrical threads, tapered threads and Turning of special threads.At the same time, it also has all the functions of ordinary CNC lathes. It can replace ordinary CNC lathes to process complex shaped shafts, sleeves, disks and other parts, such as turning inner and outer cylindrical surfaces, conical surfaces, arc surfaces, end faces , Grooving, chamfering, threading, etc., strong process adaptability, high processing efficiency, uniform product. This machine tool has a novel appearance, simple operation, mature structure and stable performance, and is widely used in petroleum, natural gas, chemical, hydropower, and geological exploration departments.
Structural features of pipe thread lathe:
1. The bed is made of high standard cast iron (HT300) secondary molding and casting. After secondary aging treatment, it has strong stability, good rigidity and strong seismic resistance.
2. The guide rail surface is subjected to high-frequency quenching (Rockwell hardness can reach HRC55 or higher). The imported guide rail grinder is used for precision grinding to ensure long life, high accuracy and good retention of the guide rail surface.
3.3 The headstock box of the 3 spindle is completed by one-time molding of the imported horizontal boring and milling machining center. The spindle has high concentricity, strong structural rigidity, and can adapt to heavy cutting. Stable, both recutting and finishing.
4. Automatic forced circulation lubrication makes the transmission system run flexibly and can effectively cool down. Each sliding rail pair is coated with TSF soft belt, which greatly reduces the friction coefficient and improves the service life of the rail.
5. Equipped with a four-station electric tool post as standard, quick and easy tool change.
