CNC Machine Tool (Specialized for Core Tube Threading)

Core Parameters

• Product Name: CNC Machine Tool for Core Tube Thread Cutting

  Equipment Positioning: Dedicated CNC equipment for core tube thread processing, used to ensure high-precision manufacturing of our core tubes. This page is for equipment introduction only.

  Core Function: Specifically designed for thread cutting, end-face machining, and chamfering of core tubes and drilling casings, ensuring stable machining quality and precision.

  Compatible Materials: Alloy steel and seamless steel pipes such as 20#, 45#, DZ40, DZ50, R780, N80, etc., commonly used for core drilling products.

  Machining Accuracy: Thread accuracy ≤ ±0.01mm, concentricity ≤ ±0.01mm. Smooth, burr-free threads fully comply with API standards and geological drilling pipe requirements.

  Features: High-rigidity CNC system ensures stable and precise machining, improving sealing performance and alignment accuracy while reducing processing errors.

  Application Note: This equipment is used exclusively for in-house core tube production. It demonstrates our strong manufacturing capability and ensures high-quality, precision-engineered products for geological exploration applications.

  
• This dedicated CNC machine tool is a core piece of equipment for ensuring the quality of our core tubes. By using high-precision CNC machining technology, it replaces traditional processing methods and enables integrated precision machining of core tube threads and end faces.

  The equipment features high machining accuracy and strong stability, ensuring uniform thread profiles, burr-free surfaces, tight connections, and excellent sealing performance. Concentricity is controlled within ±0.01mm, an industry-leading standard, effectively preventing leakage, misalignment, or detachment during drilling operations. This significantly improves core recovery rate and service life, fully demonstrating that our core tubes are high-quality and highly reliable, suitable for demanding applications such as geological exploration and mining drilling.
