The Main Parts of the CNC Pipe Threading Machine

The structural design of our CNC pipe threading machine reflects a commitment to precision and durability. Every major component of the machine body is cast from high-strength, stress-relieved iron using resin sand molding technology. This approach takes full advantage of the inherent vibration-damping properties of cast iron, ensuring that the machine maintains its accuracy over time.
During development, we applied advanced computer-based finite element analysis to optimize the design. Inside the machine, a ribbed box-type framework reinforces the structure, providing exceptional resistance to vibration, bending, and torsion. This robust design guarantees stability even under heavy cutting conditions
For auxiliary components, we use welded steel plate structures. Before welding, each plate undergoes a specialized pre-treatment process. Combined with our proven large-part welding techniques, heat treatment, and precision machining, this process effectively eliminates residual stress. As a result, these components deliver outstanding rigidity and strength, contributing to the machine’s overall reliability
In short, this CNC pipe threading machine is not just built for performance—it is engineered for longevity. Its innovative design and meticulous manufacturing process ensure superior accuracy, strength, and stability, making it the ideal solution for demanding OCTG and steel pipe threading applications.
5-Axis Feed System of the pipe threading machine Channel 2nd

The two‑axis auxiliary feed system of the cnc pipe threading machine includes a longitudinal axis (Z2) and a transverse axis (X2). Both axes move along a beam mounted on the top of the headstock. Moreover, the transverse axis (X2) and the longitudinal axis (Z2) use a servo motor, a high‑precision ball‑screw assembly, and a linear rolling guideway. As a result, the cnc pipe threading lathe achieves smooth motion and stable feed performance.
The longitudinal axis (Z2) is installed on the transverse axis (X2), which provides structural support during movement. In addition, the positioning data of both auxiliary axes is transmitted to the CNC through the servo motor encoders. This closed‑loop feedback improves accuracy and enhances the reliability of the octg pipe threading machine during demanding pipe‑machining tasks.
This auxiliary feed configuration is available as an optional feature for Channel 2. With this option, the steel pipe threading lathe gains greater flexibility for complex threading and precision pipe‑processing operations.
Conformator System

The Conformator consists of a rotating mandrel and a hydraulic cylinder. The hydraulic cylinder expands and retracts the internal stabilizer. Various stabilizer sizes can be installed, depending on the inner diameter of the steel pipe. The stabilizer is made of polyurethane, which compresses tightly against the inner wall of the pipe and rotates together with it.
Its main functions are to maintain stability during machining, reduce vibration, and lower noise. In addition, it seals the pipe end completely to prevent coolant from flowing to the opposite side of the pipe. By supporting the pipe internally, the
Conformator significantly reduces vibration during cutting, ensures smoother machining, and improves thread surface quality. It also prevents cutting fluid and chips from entering the inside of the steel pipe.
The Turret System Of the pipe Threading Machine


The Turret system of our cnc pipe threading machine is designed for speed, power, and precision. The upper Turret features a heavy‑duty five‑ or six‑station hydraulic or servo‑driven design that indexes fast, locks firmly, and delivers high positioning accuracy. The lower Turret is fixed and equally robust. Both Turrets support Capto C6 tooling for stable, high‑performance cutting.
With five coordinated feed axes driving the upper Turret (X1/Z1), the lower fixed Turret (Y1), and the Channel‑2 Turret (X2/Z2), the cnc pipe threading lathe can run three Turrets at the same time. This multi‑Turret layout accelerates OD turning, threading, and other key operations. As a result, the octg pipe threading machine achieves faster cycle times, higher throughput, and consistently accurate results.
Built for demanding pipe‑machining environments, the steel pipe threading lathe delivers the productivity and reliability needed for OCTG and industrial pipe‑processing applications.
The stop device is mounted at the front of the headstock and ensures precise positioning of the steel pipe inside the machine. It accurately stops the pipe at the required location, guaranteeing correct alignment before machining begins. Moreover, if the pipe enters the cnc pipe threading machine abnormally, the stop device absorbs the impact energy, slows the pipe down, and brings it safely to a halt. This protective function helps prevent equipment damage and ensures stable, reliable operation during high‑volume pipe‑processing tasks.
Fluid System


High‑Pressure Coolant System
The cnc pipe threading machine uses a high‑pressure, high‑flow coolant system that delivers emulsion directly through the tool head and tool‑bar channels. This targets the cutting edge for fast cooling, longer tool life, and cleaner thread quality. A chip conveyor with a return pump filters and recycles coolant, while a level‑monitoring device ensures stable operation.
Independent Hydraulic System
The cnc pipe threading lathe features an independent hydraulic pump station that controls all hydraulic functions of the machine and loading platform. A headstock‑mounted valve block manages chuck clamping, centering, the stop device, and Turret balancing. Integrated level, pressure, and oil‑temperature monitoring ensure reliable performance in octg pipe threading machine applications.
Safety and Protection System

The cnc pipe threading machine is equipped with multi‑level safety protection across the X, Y, and Z axes, including electrical limits, software limits, and mechanical limits. These layers of protection keep the machine in a safe and reliable operating state and ensure complete operator safety during all machining tasks. The bed and slideway are fully enclosed with stainless‑steel telescopic covers, effectively protecting the guideways and ball screws from chips and coolant. The machine also features a full sheet‑metal enclosure that prevents chips, oil, and coolant from splashing outside the cnc pipe threading lathe, while maintaining a clean and modern appearance.
The front safety door includes an interlock switch, and the electrical cabinet is equipped with power‑off protection when opened. These mechanisms prevent accidental operation and ensure safe access during maintenance. All safety measures comply with European CE standards, giving the octg pipe threading machine the level of protection required for demanding industrial environments and guaranteeing safe, stable performance in continuous production.
Advanced Control System

The cnc pipe threading machine is equipped with a SIEMENS or FANUC CNC system, supporting automatic, semi‑automatic, and manual control modes. The operator panel includes mode selection and real‑time status display, along with a touchscreen interface for entering key machining parameters such as pipe diameter, thread type, pipe length, cutting speed, and feed rate. It also tracks pipe counts for production monitoring.
The touchscreen enables intuitive human‑machine interaction, making programming, debugging, and maintenance fast and user‑friendly. Whether used as a cnc pipe threading lathe or octg pipe threading machine, this control system ensures precise automation and flexible operation for high‑efficiency pipe processing.
