Z30125X40 Heavy-Duty Hydraulic Radial Drilling Machine

Heavy-Duty Z30125X40 Hydraulic Radial Drilling Machine | 125mm Max Drilling Capacity

Introduction:
The Z30125X40 is a high-performance hydraulic radial drilling machine specifically designed for large and medium-sized heavy-duty workpieces. Featuring a massive 125mm maximum drilling diameter and an ultra-long 4000mm maximum distance from the spindle center to the column, equipped with a powerful 18.5KW main motor, it delivers exceptional power and stability for demanding industrial processing. Manufactured with premium high-strength cast iron and integrating an advanced hydraulic preselected variable speed system and a diamond-shaped block hydraulic clamping mechanism, this machine significantly enhances rigidity and lifespan while ensuring highly efficient and precise operations. For a complete visual reference of the equipment's robust build, please refer to the image.

Key Features & Advantages:

• Exceptional Machining Capacity & Large Stroke: Supports a maximum drilling diameter of 125mm, a horizontal traveling distance of the spindle box up to 3400mm, a distance from the spindle end face to the base working face between 750-2500mm, and a spindle travel of 560mm. It easily covers the processing range regardless of the workpiece's massive size.
• High-Efficiency Hydraulic Preselected Speed System: Equipped with a hydraulic preselected variable speed mechanism, offering a spindle speed range of 6.3-800 r/min (22 stages) and a feed range of 0.06-3.2 mm/r (16 levels). This effectively reduces auxiliary shifting time and significantly boosts batch processing efficiency.
• High Rigidity & Extended Service Life: Large foundational components such as the column, rocker arm, and spindle box are cast from high-strength cast iron. The upper guide rail of the rocker arm, the spindle sleeve, and the inner and outer column slewing races are all surface quenched, greatly enhancing wear resistance and overall service life.
• Convenient & Safe Centralized Operation: All operational handles are centrally located in highly accessible positions. The five spindle movements—forward, reverse, stop (brake), speed change, and neutral—are easily controlled by a single handle. Additionally, the machine is equipped with comprehensive safety protection devices conforming to international standards.
• Reliable Hydraulic Clamping Mechanism: The spindle box, rocker arm, and inner and outer columns utilize a hydraulic-driven diamond-shaped block clamping mechanism, providing massive and reliable clamping force. The movement of the spindle box can also be motorized in addition to manual operation, further reducing operator fatigue.
• Automatic Lubrication System: The internal spindle box, rocker arm, and column utilize an automatic lubrication system. The rocker arm guide rail and lifting mechanism use manual lubrication, ensuring all moving parts remain in optimal working condition.

Applications:
Widely suitable for drilling, reaming, countersinking, and tapping operations on large and medium-sized parts. Boring can also be efficiently carried out when equipped with appropriate process tooling.
