DGT CNC Cable Protection Tube

The DGT-type conduit protection tube is a fully enclosed steel-plastic cable protection device for machine tools. It is designed to protect cables, oil lines, and air lines during movement, and serves as an important complement to your company's existing steel drag chain product line.

2. Core Structure and Materials

2.1 Outer Shell

Made from polished stainless steel or chrome-plated steel sheet. It offers excellent corrosion resistance and impact resistance, with a smooth, attractive finish that enhances the overall appearance of the machine tool.

2.2 Inner Lining

Constructed from reinforced nylon 66 combined with fiber. This material provides high wear resistance and aging resistance, while reducing frictional damage to the cables inside.

2.3 Connectors

Available in square or angled styles to suit different mounting angles on machine tools, making installation quick and convenient.

2.4 Key Feature

The fully enclosed design prevents chips, coolant, and dust from entering, ensuring the cables and lines are protected from external environmental damage.

3. Key Advantages

Strong Protection: Fully encloses cables and lines, effectively blocking chips, oil, and mechanical impact, thereby extending service life.

Stable Operation: Low noise and low friction, well suited for short-stroke, low-to-medium speed reciprocating motion applications.

Compact and Aesthetic Design: Achieves a large internal cross-section while minimizing external dimensions, saving valuable equipment space while improving the visual quality of the machine tool.

Safe and Reliable: Prevents cable breakage caused by motion wear, reducing safety hazards and protecting operators.

4. Typical Applications

CNC Machine Tools / Machining Centers: Protects electrical, hydraulic, and pneumatic lines on moving axes of lathes, milling machines, grinders, and similar equipment.

Automation Equipment: Provides moving cable protection for automated production lines, industrial robots, and warehouse logistics equipment.

Precision Instruments: Suitable for dust-proof, oil-resistant applications with high appearance requirements, such as inspection instruments and medical devices.

Retrofit and Upgrade Projects: Used to upgrade the protection systems of older machine tools, improving both safety and aesthetics.

5. Selection and Sizing Guidelines

  • Dimensions: Choose the appropriate inner/outer diameter specification (e.g., 52×102, 70×122, etc.) based on the diameter and number of cables.

  • Material Selection: For humid or corrosive environments, stainless steel is recommended; for standard working conditions, chrome-plated steel sheet is sufficient.

  • Installation Method: Confirm the mounting angle of the equipment and select either a square or angled connector to ensure smooth operation without jamming.

  • Application Matching: Suitable for short-stroke, low-to-medium speed applications. For high-speed or long-stroke scenarios, standard steel drag chains are recommended instead.
