The Hydraulic Robust Radial Metal Drilling Machine is a powerful, versatile solution for heavy-duty drilling in construction, mining, and steel fabrication industries. Designed to handle large workpieces, this machine features a radial arm that extends drilling reach, combined with a hydraulic feed system for consistent pressure and speed during deep-hole drilling.
High-Power Hydraulic System
Drilling Capacity: Processes steel, cast iron, and aluminum up to 100mm diameter (twist drill) and 300mm diameter (core drill), with drilling depth up to 500mm.
Stepless Speed Control: Hydraulic motor (15-30kW) provides spindle speeds 50-1,500 RPM and feed rates 0.05-2mm/rev, adjustable via pressure valve.
Radial Arm Mobility
Extended Reach: Radial arm (2,000-4,000mm length) with 360° rotation, enabling drilling at any position on the worktable (1,500x2,000mm standard size).
Rigid Column: Heavy-duty steel column (300mm diameter) with anti-rotation guides, maintaining positional accuracy (±0.1mm) during arm movement.
Safety & Durability
Dual Brake System: Electromagnetic brake and mechanical lock prevent arm sagging, even at maximum extension (deflection <0.5mm).
Chip Guard & Coolant System: Full-enclosure guards and flood coolant (50L/min flow) protect operators and enhance tool life during high-speed drilling.
Easy Setup & Operation
Quick Clamping: Hydraulic workpiece clamps (4-point clamping, 50kN force) secure workpieces in seconds, reducing setup time by 30%.
Height-Adjustable Spindle Head: Electrically driven vertical movement (500-1,500mm stroke) with digital height readout (0.1mm precision).
Construction Machinery: Drilling holes in excavator arms, crane booms, and steel structural components.
Mining Equipment: Machining conveyor rollers, drill rig parts, and heavy-duty gearboxes from abrasion-resistant steel.
Steel Fabrication: Processing I-beams, flanges, and boiler plates for infrastructure projects (bridges, power plants).
Heavy-Duty Performance: Built to withstand continuous operation in harsh environments, with IP54-rated electrical components and anti-corrosive paint finish.
Customizable Configurations: Optional CNC control for automated drilling patterns, laser positioning for alignment, and mobile base for workshop flexibility.
After-Sales Support: Lifetime technical consultation and a 5-year warranty on the hydraulic system, ensuring long-term reliability.
