What is the 755 mm guideway conventional pipe threading lathe used for?

It is used for larger pipe turning and threading applications that require manual operation, stronger guideway rigidity, and larger spindle bore options.

Is this machine suitable for heavy pipe workpieces?

Yes. The wider guideway and heavier structure are suitable for larger and heavier pipes, subject to model selection and support configuration.

Can it be customized with different chucks?

Yes. Chuck and clamping options can be discussed according to pipe diameter, length, weight, and thread process.

What quotation information is required?

Please send pipe size, thread standard, material, workpiece length, weight, quantity, and destination port.

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, its core features highlight large-bore processing compatibility, high rigidity of double-chuck synchronous clamping, and long pipe processing adaptability brought by hollow spindle, with modular structure facilitating function expansion.
This robust machine is specifically designed for machining API standard tapered threads (API 5B/7-1), metric threads, and imperial threads with exceptional precision. It is particularly adept at providing high-precision repair services for various types of defective threads. Additionally, it supports operations such as turning, facing, boring, and grooving.
It has stable continuous operation performance and widely used in chemical pipeline processing, oil and gas drilling and production parts manufacturing, plumbing pipe fitting production and other industries.
