Cooling System Circulating or mist cooling

5. Working Principle

  1. The pipe is clamped by the chuck and rotated (or the tool rotates);

  2. The tool feeds along the pipe axis via feed mechanism;

  3. The cutting tool creates threads according to set parameters;

  4. After threading, the tool retracts automatically or manually;

  5. Cooling system minimizes thermal deformation and extends tool life.


✅ 6. Application Scenarios

  • Oil & Gas: API casing and drill pipe threading

  • 🚰 Water Supply & Drainage: Galvanized and black steel pipe threading

  • 🔥 Fire Protection Systems: Firefighting pipe threading

  • 🏗️ Construction: Electrical conduit and HVAC pipe threading

  • ⚙️ Hardware Workshops: Custom batch thread cutting


✅ 7. User Feedback Summary

  • High Precision: Threads are smooth and meet international standards

  • 🔄 Easy to Operate: Especially CNC versions with user-friendly interface

  • 🧰 Low Maintenance: Modular design for quick part replacement

  • ⏱️ Efficient: Short processing cycles, ideal for batch work

  • 💰 Cost-Effective: Local machines offer good performance-to-price ratio

  • ⚠️ User Tip: Change tools regularly during heavy-duty operation to maintain quality
