QLK1325 Pipe-Threading CNC Lathe
1.Extra-large Workpiece Capacity
The maximum swing diameter of the bed is Φ820mm;
the maximum swing diameter of the slide is Φ500mm;
the maximum workpiece length is 1500mm-3000mm;
the processing pipe diameter is Φ60–250mm, covering mainstream specifications such as oil casing, tubing, and drill pipe.
2.Multi-Functional Machining Capabilities
In addition to internal and external tapered threads , the machine can turn external diameters, bore holes, face surfaces, and chamfers.
It accommodates both shaft and disc-type parts, offering multi-purpose functionality and reducing equipment costs.
3.Dual Four-Jaw Chuck Configuration
Front and rear Φ630mm manual four-jaw chucks provide secure clamping, accommodating irregular tubular parts and long workpieces while ensuring easy maintenance of coaxiality.
4.Reliable Load-Bearing and Structure
The width of the bed way is 600mm, and the max load capacity is 3T.
It has strong structural stability and can handle the processing of workpieces with a certain weight.

Advantages
Large spindle through hole, high passability, double chuck workpiece clamping stability;
High quality high strength cast iron overall bed rigidity, high precision;
The surface of the guide rail is quenched by super audio hardening, with high hardness and
long accuracy retention.
The drag plate adopts the process of guideway surface plastering, which has low friction
resistance, good wear resistance and high precision.
Applications
This machine tool is designed for large-diameter, heavy-duty cutting, and high rigidity. It is primarily used for machining internal and external threads on medium- to large-sized tubes, while also supporting the turning of shaft and disc-type components, such as large-diameter shafts, flanges, and discs—including external cylindrical surfaces, internal bores, and end faces.
With a bed width of 600–650 mm, it features a wide-bed, heavy-duty configuration, making it suitable for applications in the petroleum, chemical, geological, coal machinery, and pipeline network construction industries.
