|---|---|
Its radial arm design and powerful hydraulic system enable efficient processing of oversized workpieces, combining reach, rigidity, and precision for demanding industrial applications.
Heavy-Duty Radial Configuration
Extra-Long Reach: 4,000mm radial arm with 360° rotation and 2,000mm vertical travel, covering a work area of 5,000x3,000mm (expandable with optional extension tables).
High-Torque Hydraulic Drive: 30kW hydraulic motor provides spindle speeds 15-600 RPM and feed forces up to 100kN, capable of drilling 80mm diameter holes in 600MPa tensile strength steel.
Rigid Structural Design
Box-Section Column: 400mm diameter steel column with internal ribbing (yield strength ≥345MPa), reducing deflection under full load to <0.3mm at maximum extension.
Anti-Friction Bearings: Radial arm supported by pre-loaded roller bearings (life rating L10 ≥10,000 hours), ensuring smooth movement and long-term accuracy.
Productivity-Enhancing Features
Dual Spindle Heads (Optional): Mount two drilling spindles (main + auxiliary) for simultaneous hole processing, increasing output by 50% for repetitive patterns.
Quick-Change Tool Holder: Hydraulic tool clamping system (ISO 50 taper) enables tool swaps in <10 seconds, with automatic spindle alignment (radial runout <0.05mm).
Safety & Maintenance
Full Enclosure Guarding: Polycarbonate safety shields with interlock switches, compliant with OSHA 1910.212 and CE machinery directives.
Centralized Lubrication: Automatic grease pump (10-point lubrication system) with pressure sensors, reducing maintenance downtime by 40%.
Shipbuilding: Drilling hull plates, propeller shafts, and marine engine components from high-strength marine steel (e.g., AH36, DH36).
Energy Infrastructure: Machining wind turbine flanges, boiler tubes, and nuclear power plant components requiring large-diameter holes (up to 150mm).
Heavy Fabrication: Processing mining equipment frames, bridge girders, and offshore platform structures with complex hole patterns.
Industrial-Grade Durability: Designed for 20+ years of service in harsh environments, with anti-corrosive epoxy paint (500-hour salt spray resistance) and IP65-rated electrical components.
Customizable Work Envelope: Available with extended column heights (up to 5 meters) and heavy-duty rotary tables (load capacity 10-50 tons) for machining.
Comprehensive Service Package: Includes on-site installation, operator training, and a 3-year warranty covering all mechanical and hydraulic components.
