RADIAL DRILLING MACHINES 2A554; 2A554-1; 2A554-2; OC2146; OC2567; 2A576; 2A587
1. TECHNICAL DESCRIPTION
1.1. Radial drilling machines can be used for drilling, boring, reaming and taping.
1.2.The arrangement of the machines is traditional for radial drilling machines and includes:
- The stationary base plate with T-slots for clamping the work pieces, fixed on foundation, on which either socle (2A554; 2A554-1) or stationary inner pillar (OC2146; OC2567; 2A576 and 2A587) is mounted.
- The pillar, rotating round the vertical axis together with the sleeve, by means of socle bearings (2A554; 2A554-1; 2A554-2), or the outer pillar, rotating by means of bearings round the inner pillar (OC2146; OC2567; 2A576 and 2A587).
- The sleeve provided with possibility of vertical travel along the outer pillar and rotation round the vertical axis together with it.
- Drilling head, provided with possibility of horizontal travel along the sleeve guides
- Spindle, mounted in cylindrical quill, provided with possibility of vertical travel in the drilling heads housing.
1.3. Feed is provided by spindle quill. All the rest travels are positioning.
1.4. All the displaceable parts of the machines are moving with minimized efforts and are fixed in operating position by means of hydraulic clamping devices.
1.5. All the control devices are concentrated in the control panel of the drill head.
1.6. The preliminary selection for spindle revolution and feed and the hydraulic gear changing devices provide low spindle speed and feed changing time.
1.7. The friction clutches, built in the gearbox, provide quick spindle reverse while taping and prevent the gears from overload while machining.
1.8. The spindle of the machine is counterbalanced in any point of its travel.
1.9. The hand wheel type device for drill head control has the possibility of switching off the mechanical feed after reaching the selected drill depth.
1.10. The 2A587 machines are equipped with the devices for power travel of the drill head and column rotation.
1.11. Standard power supply – 380V, 50Hz. Electric apparatus installing for other different power supply is possible for extra payment.
