Radial Drilling Machine

AR Series of radial drills from Arsun Engineers are designed to offer rigidity, precision and easiness in operation. Model AR50 has drilling capacity of 50 mm in steel and 60 mm in cast iron. Its drilling motor power is 3.7 kW (5 HP) and arm lifting motor power is 1.1 kW (2 HP). The machines have robust structure with generously provided ribs and appropriate wall thickness for base-plate, arm, inner column and column sleeve and are rigidly built to withstand static as well as severe dynamic loads. The drill-head comprises of a gearbox and a feedbox fitted with hardened gears on spline shafts running on antifriction bearings in an oil bath, offers 8-speeds and 5-auto feeds. Auto feed disengages automatically when reaching at preset drilling depth or against too high drilling pressure, thus prevents breakages or damages to the internal moving parts. Main specifications: speed-range 45-1100 RPM; auto feed range –0.05 to 0.25 mm per rev of spindle; 300 mm ram travel; and drilling radius is 535/1375 mm. D
