Product Description

Deep hole Gundrilling machine feature

A deep hole gundrilling machine is a specialized industrial tool designed for creating long, precise holes in various materials, with distinct characteristics that set it apart from conventional drilling equipment: -

 **Exceptional Depth Capacity**: It excels at drilling holes with a high depth-to-diameter ratio (often exceeding 100:1), making it ideal for applications requiring deep, narrow bores in components like hydraulic cylinders, mold plates, or aerospace parts. -

 **Superior Precision**: Equipped with advanced guiding systems and high-stiffness spindles, it achieves tight tolerances on hole diameter, straightness, and concentricity, typically within ±0.01 mm for diameter and 0.05 mm/m for straightness. -

**Integrated Coolant Systems**: A hallmark feature is its high-pressure coolant delivery (often 50-1000 bar), which flushes chips out of the deep hole, lubricates the cutting edge, and prevents overheating-critical for maintaining tool life and hole quality. -

 **Specialized Tooling Compatibility**: It is engineered to work with gundrill bits, which have a unique single-flute design with an internal coolant channel. This tooling, combined with the machine's rigid structure, ensures efficient chip evacuation and stable cutting even in deep holes. -

**High-Speed Performance**: Many models offer variable spindle speeds and feed rates, optimized for different materials (e.g., metals, composites) to balance productivity with precision, reducing cycle times without compromising hole integrity. -

 **Automation and Versatility**: Modern versions often include CNC controls for programmable operations, enabling automated drilling sequences, repeatable accuracy, and adaptability to diverse part geometries-from simple straight holes to stepped or tapered bores. -

**Rigorous Stability**: Built with heavy-duty frames, reinforced guideways, and anti-vibration components to minimize deflection during long drilling cycles, ensuring consistent performance even when working with hard or tough materials like alloy steels or titanium. These features collectively make it indispensable in industries where deep, precise holes are critical to functionality, such as automotive, energy, and precision engineering.
