Cnc Pipe Threading Lathe
CNC LATHE USE
The QK1325 CNC Pipe Thread Lathe is capable of machining:
Pipe thread types: API Spec 5B, API Spec 5CT, API Spec 7-1, API Spec 7-2, various drilling tools, metric and imperial threads for casing and tubing, as well as specialised threads.
Primarily designed as a dual-axis, dual-interpolation CNC lathe to address semi-finish and finish turning of shaft and disc components, alongside drilling and tapping operations. Equipped with an advanced CNC system, it not only performs straight, inclined, and circular arc turning (cylindrical surfaces, rotational surfaces, spherical surfaces, conical surfaces), straight and tapered metric and imperial threading, but also possesses capabilities for drilling axial holes and thread machining. This makes it suitable for processing complex-shaped, high-precision disc-type, sleeve-type, and shaft-type components.
The machine tool features an integrated flat bed, facilitating convenient operation and adjustment while aiding chip removal and workpiece loading/unloading. The longitudinal and transverse guideways are medium-frequency hardened, enhancing machine response speed and extending service life. The spindle drive system employs a wide-speed-range AC variable-frequency main motor, transmitting power to the spindle via a belt and headstock gearbox. Both X and Z-axis drives utilise direct-coupling, enhancing machine stability, reliability, and responsiveness.
The machine's styling embodies contemporary aesthetics, combining visual appeal with practicality and ergonomic design. Electrical components are stable and reliable. The CNC system employs AC digital drive technology with semi-closed-loop feed axis control, delivering robust performance and strong interference resistance. Advanced features include pitch error compensation, constant linear speed cutting, fixed cycles, direct drawing dimension programming, and DNC communication. The machine exhibits rapid overall response and excellent dynamic rigidity, ensuring superior quality.
product key technologies
Bed
The bed employs an integral cast structure of HT300 grey cast iron, with a width of 600mm and a 'mountain-flat' guideway configuration. Its internal rib layout is rationally designed, delivering high rigidity that fully guarantees machine stability during machining of large-diameter components. The guideways undergo medium-frequency quenching and grinding, achieving high hardness with a deep hardened layer. Anti-creep guide plates are fitted to the sliding surfaces, optimising the feed system's dynamic characteristics-including rigidity and friction damping coefficient-to eliminate low-speed creep phenomena.
Spindle Head
The machine tool headstock adopts a symmetrical structure to ensure uniform thermal deformation and prevent offset of the spindle centre. Power is transmitted to the spindle via a belt and headstock gearbox from the variable frequency motor. During headstock design, measures were implemented to enhance spindle precision and rigidity, including: grinding the spindle to match the bearing inner ring, boring the housing bore to match the bearing outer ring, and preloading the spindle bearings. Furthermore, all internal gears undergo quenching and grinding processes, ensuring precise transmission and low noise levels. The meticulously assembled spindle exhibits low temperature rise, minimal thermal deformation, and high precision, maintaining stable performance characteristics during prolonged operation. Precision spindle bearings are selected for the spindle housing. To minimise machine tool thermal deformation, enhanced heat dissipation measures are incorporated, with the headstock employing oil bath lubrication.
The headstock gear selection offers both manual and hydraulic shifting options.
Spindle head specifications:
Short cylindrical
Front bearing bore: 300 mm
Spindle taper bore: 1/20
Rear bearing bore: 300 mm
Feed System
The X and Z-axis feed drives employ large-diameter, high-precision ball screws with preload and pre-tensioning. Specialised angular contact ball bearings for ball screws are fitted at both ends to ensure motion and positional accuracy. The feed motors are directly coupled to the ball screws, eliminating backlash and vibration. Machines with processing lengths of 7 to 10 metres employ a rotating nut structure. With the ball screws fixed at both ends, synchronous belts control the rotation of the screw and nut assembly. This prevents whipping caused by excessive rotation of the long screws, thereby guaranteeing machining precision. Prior to dispatch, dynamic accuracy testing and compensation are performed using Renishaw laser measurement systems from the UK, ensuring high positioning accuracy.
X and Z-axis guideways undergo medium-frequency quenching followed by precision grinding. Wear-resistant materials are applied to moving surfaces, supplemented by an automatic guideway lubrication system providing continuous forced lubrication to minimise friction. This ensures an optimal combination of feed accuracy and rigidity.

Tool Turret
The standard tool turret employs a four-station electric turret from a renowned domestic brand, characterised by high precision, smooth rotation, and streamlined operation.
Upon customer request, horizontal tool turrets from internationally recognised brands-including 8/12-station servo turrets, hydraulic turrets, electric turrets, and power turrets-may be installed (cutting length will vary accordingly).
4-Station Tool Holder
8-Station Horizontal Turret(Optional)
The tailstock mounting bracket is optional.
Tailstock
The machine tool comes standard with a manual tailstock, featuring a tailstock centre.
Axial movement of the sleeve can be controlled via a handwheel.
To remove the centre, rotate the sleeve backwards until the threaded end engages the centre,
then push the centre out. The tailstock assembly may be moved by pulling the hook on its lower section; alternatively, a bracket and gear mechanism may be employed per customer specifications. Special configurations such as hydraulic tailstocks, rotating tailstocks, and electrically powered tailstocks are available upon request.
Boring Bar Holder and Hydraulic Centre Support (Optional)
To facilitate boring operations, the machine tool may be fitted with a lightweight boring bar holder or a linear guide boring bar holder on the saddle. The bore diameter of the holder can be customised to customer specifications: the lightweight holder accommodates diameters ranging from φ60 to 100mm, while the heavy-duty holder accommodates diameters from φ100 to 140mm.
The machine tool may be fitted with a hydraulic centre support, whose opening and closing can be conveniently controlled via M codes. This enhances clamping precision compared to manual centre supports, with a maximum clamping diameter of φ320mm.

Hydraulic Centre Stand (Optional)
Power Output
The spindle motor employs a high-performance AC variable-frequency drive motor from a renowned domestic brand, featuring in-gear stepless speed variation. With a power rating of 15 kW and manual four-speed control, it delivers substantial torque output across a broad range, achieving high torque even at low rotational speeds.
Motor Power Chart Motor Torque Chart
Note: The torque of the 22kW motor is 140Nm; simply calculate the multiplier accordingly.
Cooling
The cooling system employs multi-stage filtration to thoroughly purify the coolant, minimising the risk of cooling circuit blockages. Separation of the water tank from the main unit reduces the impact of cutting heat on machine tool precision. The cooling pump delivers a flow rate of 22 litres per minute with a head of 3.3 metres, while the cooling tank capacity is 70/120 litres. During turning operations, both workpiece and cutting tool are adequately cooled, enhancing machining accuracy and extending tool life.
Electrical System
All power circuits in the machine tool are equipped with overcurrent and short-circuit protection. Interlocking mechanisms safeguard against unauthorised operations, ensuring equipment and personnel safety.
The electrical system incorporates self-diagnostic functions. Operators and maintenance personnel can monitor the operational status of all machine components via indicator lights and displays.
The electrical cabinet employs an enclosed design with fan-assisted cooling to achieve dust protection and temperature regulation. It meets IP54 protection rating requirements.
Guarding
Machine tools up to 6 metres in length are standard-fitted with semi-enclosed guards. Those exceeding 6 metres utilise simplified guards, though full enclosures with chip conveyors may be fitted per customer requirements.
Safety Protection
The machine incorporates alarm systems and emergency stop buttons to mitigate damage from sudden malfunctions. Through intelligent software design, alarms are displayed via text and alarm codes on the monitor or indicated by indicator lights on the control panel. Alarm handling is categorised into three levels: emergency alarms trigger an immediate 'emergency stop'; general alarms activate 'feed hold'; operational errors receive a 'prompt' notification only.

1. When using a chuck exceeding standard specifications, for every 8mm increase in jaw diameter, the corresponding speed decreases by 10%. For every 30mm increase in jaw length beyond the standard, the corresponding speed also decreases by 10% (multiple exceedances result in cumulative reductions).
2. Dynamic balancing is required when clamping irregularly shaped, oversized, or excessively long workpieces. The workpiece diameter must not exceed the chuck diameter. Should the exposed length of the workpiece protrude beyond the chuck thickness, a 10% reduction in speed applies for every 30 millimetres of excess length.
