Description:	Precision Ring Drilling Rig ELHA S 4119 used machine Pos. 1.0 Precision Rotary Table Make EIMELDINGEN with aerostatic axial bearing Specifications Table diameter 3,400 mm Total height approx. 1,230 mm Centering bore Ø 250H7X 25 mm Permissible transport load 20,000 kg Holding torque of the table clamping 2,400 daNm Table speed 0.002 – 2 min Net weight approx. 22,000 kg Operating voltage 380 V, 50 Hz. 3 phases Control voltage 24V Positioning accuracy (without control errors) ± 1" Plan accuracy 0.02 mm Axial running accuracy 0.01 mm Concentricity deviation of the centering bore 0.01 mm Resolution of the displacement measuring systems 0.0001° Pos. 2.0 3-Axis Cross Bed Boring Mill Specifications Column stroke transverse "X" 500 mm Carriage stroke horizontal "Z" 650 mm Spindle box vertical "Y" 800 mm Rapid traverse speed Y + Z 8,000 mm/min Feed speed (infinitely adjustable) 0-1000 mm/min Spindle drive power 15 kW Spindle diameter in the front bearing 100 mm Speed range 0-4000 rpm Tool holder ISO 50 Accuracies For all axes Position tolerance Tp (1000) 0.012 mm Position spreading width Ps 0.008 mm Position deviation PA 0.008 mm Measurements are carried out at room temperature + 20°C. Item 3.0 Grinding device for clamping device The grinding unit for the clamping device can be removed and can also be used on other machines. It stands on an adjustable base plate installed under the hallway. The opening is covered during normal operation. The motor grinding unit, which is equipped with a cup grinding wheel, can be adjusted in 2 axes by means of 2 slide units and an intermediate stand. The adjustment is done by hand via fine adjustment spindles. When grinding the clamping device, the circular dividing table rotates at a constant speed. Grinding is a manual process. Diameter, axial run and concentricity are checked with the measuring device in station 4. Pos. 4.0 Coolant system/chip disposal A generously dimensioned chip and coolant channel leads around the circular dividing table. In the area of Unit 1, it is interrupted and leads coolant and chips into the central system or onto the chip conveyor. The chip conveyor integrated into the intermediate piece between unit 1 and the circular table substructure is connected to an intermediate tank. A float switch-controlled lifting pump pumps the coolant into the paper belt filter system, which is attached to the main tank. The paper belt filter system is equipped with an automatic paper transport controlled by a float H41228030 switch. A separate system keeps the coolant at a constant temperature. To do this, the coolant is circulated in the main tank. To compensate for the temperature of the entire system, there should always be a larger amount of coolant in circulation. Total amount of coolant 1,200 l High pressure pump for unit 1 60l/min 10 bar Low pressure pump for units 2+3 40 l/min 2 bar Mud pump 200 l/min 0.2 bar The pressure of the high-pressure pump is monitored. A flushing hose for cleaning the workpiece and clamping device is available. General: Data of the entire system Footprint of the entire system approx. 8,800x10,800 mm Base area of the actual machine approx. 8,000 x 6,200 mm Max. machine height without workpiece approx. 3,700 mm Max. machine height with workpiece approx. 5,500 mm Operating voltage 380 V. 50Hz.
