Hydraulic Robust Radial Metal Drilling Machine

Radial drilling machine, also can be called as radial drill. Radial drill is a kind of hole processing equipment, can be used for drilling, reaming, reaming, tapping and scraping the end face, and other forms of processing. According to the machine tool clamping structure classification, slewing drilling can be divided into hydraulic radial drilling machine and mechanical radial drilling machine in all kinds of drilling machine, radial drilling machine is easy to operate, flexible and applicable scope is wide, typical, especially suitable for single piece or mass production with porous hole machining of large parts, is a common machine tool general mechanical processing workshops.

Overview


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.


Features


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).


Application


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).


Why Choose Us


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.
