High-torque industrial radial drilling machine for large-scale hole drilling in heavy fabrication and structural steel

Typical Applications

  • Drilling operations on large plates, frames, and base structures in fabrication and heavy engineering workshops.

  • Turbine casings, pump bodies, and large housings in power and cement plant maintenance shops.

  • Bogie frames, couplers, and underframe components in railway workshops.

  • Defence workshops machining armour plates and heavy vehicle components where workpiece movement is impractical.

Machine Description
  • • Heavy-duty radial drilling machine designed for drilling operations on large and stationary workpieces.
  • • Radial arm allows the drilling head to reach across a wide working radius, avoiding the need to reposition heavy components.
  • • Rigid double-column structure providing load-bearing capacity and stability during large-diameter drilling at extended reach.
  • • Hardened and ground alloy steel spindle and gearing, suited for sustained drilling duty.
  • • Electro-mechanical clamping of the drill head and arm, ensuring rigidity during heavy drilling operations.
  • • Friction disc clutch mechanism protects the transmission during start, stop, and overload conditions.
  • • Optional hydraulic clamping available where frequent repositioning or higher productivity is required.

Accessories

  • • Cast Iron Box Table, Universal Tilting Table.
  • • Drill Chuck, Drill Vice.
  • • Coolant System, Machine Lamp.
  • • Tapping Attachment.

Configuration Notes

  • 1. Model selection is driven by drilling radius, component material and working envelope, not drilling diameter alone.
  • 2. Suitable for drilling, tapping (with attachment), and counterboring operations on large components.
