Heavy-Duty Z3050 Metal Radial Drilling Machine

Overview

Built to handle large workpieces, its radial arm configuration and hydraulic feed system enable precise drilling of deep, large-diameter holes in tough materials like high-strength steel and cast iron.

Features

Industrial-Grade Hydraulic System

Massive Drilling Capacity: Processes holes up to 50mm diameter (twist drill) and 100mm diameter (core drill) with depths up to 500mm, supporting axial forces up to 80kN.

Variable Speed Control: Hydraulic motor (22kW) provides stepless spindle speeds (25-800 RPM) and feed rates (0.08-2.5mm/rev), adjustable via pressure-compensated valves for optimal chip evacuation.

Rigid Radial Arm Design

Extended Working Range: 2,500mm radial arm with 360° rotation and 1,500mm vertical travel, covering a work area of 3,000x2,000mm (standard table size).

Dual-Guide Column: Heavy-duty steel column (350mm diameter) with anti-friction linear guides, ensuring positional accuracy (±0.15mm) even at maximum extension.

Durability & Safety

All-Metal Construction: Stress-relieved welded steel frame (5,000kg net weight) with anti-vibration mounts, capable of withstanding continuous heavy loads in harsh environments.

Integrated Safety Features: Full-enclosure chip guards, emergency stop sensors, and overload protection (hydraulic pressure cutoff at 120% rated load).

User-Centric Operation

Powerful Clamping System: Four hydraulic workpiece clamps (100kN total force) with quick-release levers, reducing setup time for large components (e.g., I-beams, machine frames).

Digital Depth Control: Magnetic scale feedback (0.01mm resolution) for precise depth setting, with mechanical depth stops to prevent over-drilling.

Application

Steel Fabrication: Drilling flange holes, beam connections, and boiler plate components for bridges, power plants, and industrial facilities.

Construction Machinery: Machining excavator arm pivots, crane boom sections, and hydraulic cylinder mounts from abrasion-resistant steel (e.g., HARDOX 450).

Mining Equipment: Processing drill rig components, conveyor rollers, and heavy-duty gearboxes requiring deep, accurately positioned holes.

Why Choose Us

Heavy-Duty Performance: Proven reliability in 24/7 operation with MTBF >15,000 hours, supported by a 5-year warranty on the hydraulic system.

Precision Engineering: Laser-aligned column and arm ensure geometric accuracy (ISO 230-2: ≤0.1mm/m vertical deviation), critical for structural integrity.

Customizable Options: Available with CNC control (for automated drilling patterns) and mobile bases (for on-site construction projects).
