CNC Pipe Threading Lathe with Hydraulic Tail Stock

This series of heavy duty CNC pipe threading lathe is mainly designed for processing internal and external pipe threads of large size pipe, including metric, inch, module, DP and taper threads, as well as having all the common functions of regular CNC lathe such as processing the outer circle, inner bore and end face of shafts and disks, etc.

Product Introduction


The CNC Pipe Threading Lathe with Hydraulic Tail Stock merges automation with precision to streamline pipe and tube machining processes. Developed specifically for the oil, gas, and plumbing industries, this lathe automates threading, grooving, facing, and chamfering operations, reducing reliance on manual labor while improving consistency across batches. Its hydraulic tail stock ensures secure workpiece clamping, making it ideal for high-volume production of standard and custom pipe threads.


Product Advantages


Automation

CNC programming eliminates human error in thread cutting, ensuring consistent pitch, depth, and angle across 1000+ workpieces. Batch changeovers take less than 10 minutes via program recall, ideal for large-scale production.


Efficiency

Threading cycle times are reduced by 30% compared to manual lathes (e.g., 1.5 minutes per 6-inch API pipe vs. 2.5 minutes manually). The automatic chip conveyor (included) further reduces downtime for debris removal.


Safety

A full enclosure with interlocked doors prevents access to moving parts during operation, while a hydraulic overload system stops the turret if it encounters excessive resistance, protecting tools and workpieces.


Features


CNC Control

Equipped with a Siemens 828D or Fanuc 0i-TF CNC system, featuring a 10.4-inch color display and intuitive programming interface. Supports G-code, M-code, and conversational programming for quick setup of complex thread profiles.


Hydraulic Tail Stock

The tail stock generates adjustable clamping force (0–5 tons) via a hydraulic cylinder, with a 250mm stroke and position feedback (resolution

0.01mm) for precise alignment. It automatically retracts after machining to reduce cycle time.


High-Speed Threading

Specialized thread-cutting algorithms enable speeds up to 500 RPM for API (5L, 5CT), NPT, BSP, and metric threads, with thread accuracy within ±0.01mm for pitch and angle. The lathe stores 100+ preset thread programs for quick recall.


Modular Tooling

A 12-station turret (indexing time

0.5 seconds) accommodates carbide inserts for threading, turning, and grooving, with tool life monitoring (optional) to alert operators when tools need replacement.
