Conventional pipe threading lathe Oil Country Lathe machine

Pipe threading lathe is also known as big bore lathe machine, Large bore lathe, oil country lathe, double chuck lathe, oil field lathe and hollow spindle lathe.
It adopts a hollow spindle design to ensure through processing of large-bore workpieces, a double-chuck clamping system to improve clamping stability and precision, and integrates the high-load adaptability of oil country lathe, with modular design for easy debugging.
In terms of functions, it can accurately process metric, imperial and API 5B (petroleum pipeline standard) tapered threads, support DP (diametral pitch) parameter adaptation, and is equipped with efficient thread repair function, which can accurately repair defective threads such as worn and deformed ones. It realizes composite processes such as thread processing, end turning and repair, greatly improving processing efficiency and workpiece utilization. It is widely used in petroleum and natural gas pipe fitting processing, municipal pipeline manufacturing, mechanical parts production and other industries.

Chuck

This dual-chuck setup provides exceptional flexibility for handling long or complex workpieces, enabling simultaneous workholding at both ends for increased stability and efficiency

Q1213 Series Lathes come standard with dual Φ400 mm 3-jaw hollow chucks

Q1219 & Q1222 Series Lathes feature dual Φ520 mm 4-jaw hollow chucks as standard equipment.

Other manual 4-jaw and 3-jaw chucks are for option.

Tailstock

The center line of tailstock spindle is horizontally zeroed to the center line of the headstock spindle. The center line of tailstock spindle has been well adjusted before lathe leaves the factory. There is a zero line mark at the convex plane between the right lower tailstock body and the base.

Toolpost

There are 4-position toolpost, 6-position toolpost, quick change toolpost and other toolpost for optional. Standard configuration is 4-position vertical toolpost.
