Radial Drilling Machine

Arsun Engineers offers AR Series of Radial Drills, which are designed to offer rigidity, precision and easiness in operation. The model AR50 is having drilling capacity of 50-mm in steel and 60-mm in cast iron. Its drilling motor power is 3.7 kW (5HP) 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 45–1150 rpm; auto feed range 0.05 to 0.25-mm per rev of spindle, 300-mm ram travel (drilling depth) and drilling radius is 540/1350-mm. Its double column design, wide clamping area of base plate along with ample rigidity of the machine makes is suitable for drilling, tapping, reaming and boring operations. These machines find application in engineering workshops, fabrication shops, die, mould and machinery manufacturing, automobile and shipbuilding industries, railways, defense, etc.
