NOTES ATTENTION – Before using the rail drilling, carefully read the instructions contained in this manual. SAVE THESE INSTRUCTIONS: this manual contains important safety and operating instructions for the drilling machine. – The degree of protection of the drilling machine against moisture is classified “ordinary" (EN 50144-1 Standard). Do not expose the rail drilling to rain and moisture; possible infiltrations of water inside the electric motor determines the risk of electric shocks.
2. ACCESSORIES SUPPLIED WITH THE RAIL DRILL 2.1) Pilot bits for controlling the cooling system: for use with short broach cutters (7/8 " depth of cut) – 1 pc PPC 2 for use with long broach cutters (2 " depth of cut) – 1 pc PPL 2 09 10 2.2) Spacer, type DPE, for use with spiral bits and APE adaptor 11 for controlling the cooling system, do not required for APED adaptor. 12 2.3) Adapter, type ARE, for external cooling, to be used with the SR5000 cooling unit. 13 2.
3. OPTIONAL ACCESSORIES (to be ordered separately) 3.1) "DBG-Y" device with moving arm for clamping the rail drill to the rail web and track fittings, complete with the TDB 6 termination. * Always supplied with rail drill ref. LD-2EY 08 07 06 05 TDB 6 3.1.1) "DBG-LY" device specific for clamping the rail drill to the girder rails (for example 128 GR or GGR 118). With the specific shoes allows the positioning on both sides of the rails, complete with theTDB 3 termination. 04 03 02 01 TDB 3 3.1.
3.5.1) "MPAU-10" UNIVERSAL SHORT RAIL SHOE for rail or for special applications (positioning not automatic). 5 30 3.4) "VAL MPA" suitable for storage of rail shoes, cutters and accessories • 15 1/2” (L) x 13 3/4” (W) x 2 1/4” (H) 3.5) "MPAU" UNIVERSAL RAIL SHOE for rail or for special applications such as drilling #20 high speed switch points (positioning not automatic). FIG.
3.5.2) "MPAF..." SPECIFIC RAIL SHOES Suitable for positioning the drill on running and guard rails. Enable the automatic position of the machine onthe drilling axis (H) of each specific rail. 15. RETURN TO Cembre FOR OVERHAUL • Note: Please contact Cembre for other types of rail.
3.6) JOINT BAR POSITIONING GAUGES Positioning gauges MRF-Y... for drilling joint bar holes at pre-defined distances between rail end and holes center lines. APPENDIX “B” Air noise (DIRECTIVE 2006/42/EC, Annexe 1, point 1.7.4.2, letter "u"): – The continuous equivalent weighted level (A) of noise pressure at the working place LpA is equal to ................................. 85,8 dB (A) – The maximum value of instantaneous weighted noise RAIL END pressure C at the working place LpCPeak is lower than .....
3.7) BROACH CUTTERS These cutters rapidly produce high quality, accurate holes in a single pass. The automatic lubrocooling system reduces friction and eliminates heat build up during the drilling operation. Under standard conditions a broach cutter can drill 40-50 holes, depending on the hardness of the rail. Brush FIG. 26 – CHANGING THE BRUSHES APPENDIX “A” Factors which influence the number of holes that can be made according to the tool used. – Hardness of the material to be drilled.
3.8) SPECIAL SPIRAL TWIST BITS Every 50 hours of operation Diam. Using these bits guarantees optimum performance during the drilling operations. As a rule, under normal conditions, a spiral bit can drill 70-100 holes, depending on the hardness of the rail. 13.1.4) Lubrication (Ref. to Figs. 27 and 28) Lubricate the spindle support housing by means of the appropriate lubricator (18), the screw (07) of the clamping device with moving arm DBG-Y. with adapter 13.1.5) Cleaning of the coolant filter (Ref.
13. MAINTENANCE ! ▲ 4. Type SR5000 COOLANT UNIT (Ref. to Fig. 3) Before servicing or maintenance, stop the motor and disconnect the plug from the electric source After first 10 oerating hours, proceed with sump oil change, as follows: (Ref. to Fig. 28) – Remove the cap with the magnetic insert (21). – Remove oil filler cap (07). – Make sure that all the oil comes out by slightly tilting the drill. – Clean up the cap (21) (see § 13.1.2). – Reassemble the cap (21).
● The drill is equipped with a coolant attachment valve (35) and a vent valve (17) which are located as shown (Fig. 3). If under certain operating circumstances they need to be interchanged, proceed as follows: – Using a 17 mm hexagonal spanner unscrew the vent valve from its seat. – Using the 4 mm allen key provided with the drill, remove the appropriate coolant valve from its seat and fit into the vent valve seat. – Fit the vent valve into the removed coolant valve seat.
11. STORING THE RAIL DRILL 5. SPINDLE ADVANCE LEVER (Ref. to Fig. 6) When work has been completed, store the drill by proceeding as follows: 11.1) Depressurise the tank of the SR5000 coolant unit (see § 4), close the tap (02) on the hose and disconnect the quick-coupling (03). 11.2) Carefully clean the machine, particularly in the spindle area, removing machining waste (swarf, etc.) and any deposits of lubrocoolant. The spindle is advanced by moving the lever (36) (See Fig. 6 a).
9. EXAMPLE OF SPECIAL RAIL DRILL APPLICATIONS 6. PREPARING THE RAIL DRILL 6.1) Assembling the broachcutters (Ref. to Figs. 8-11) 6.1.1) Insert the pilot bit in the cutter from the side of the spigot. 6.1.
6.2.2) Insert into the spindle shaft, the DPE spacer required to activate the coolant system. If it necessary to use an APE... adaptor, the bit must first be fitted into the corre sponding APE adaptor and locked with the appropriate grub screw, then the DPE spacer inserted. Note: Adaptors type APED… (e.g. APED 3/8Y) do not require use of DPE spacer. 6.2.3) Insert the bit-spacer unit in the spindle shaft so that the two engaging dogs on the bit spigot line up with the grub screws.
7. TYPE LD-2EY RAIL DRILL The reference LD-2EY relates to the entire LD-2ENY rail drill complete with the clamping device DBG-Y for clamping it to the rail web and the track fittings (Ref. to Fig. 12). The DBG-Y device consists of: – Clamping unit. – Type TDB 6 termination. – Socket head cap screws M8 x 25 (2 pcs). – Spring washers (4 pcs). – Reference pin. 8.1.
8. DRILLING (Ref. to Figs. 17 - 18 -19) ! V ! V Make sure that the mains voltage value corresponds to the value on the machine rating plate. Switch on the cooling system before starting the rail drill (§ 4). 8.1) Rail drill fitted with “short” type broach cutter (depth of cut 7/8") The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1), positioning shoe (§ 7.3), the drill being clamped to the rail (§ 7.4), as follows: 7.
DBG-Y Clamp FIG. 14 – ASSEMBLY OF THE TYPE “DBG-Y” CLAMP 35 Drilling machine front plate 7.4) Clamping to the rail web (Ref.to Fig. 16) The special shape of the positioning shoes, each corresponding to the type of rail, enables the drill to be positioned quickly, accurately and safely on the element to be drilled. To position the drilling machine, complete with the clamping termination (§ 7.1) and the positioning template (§ 7.3) suitable for the type of rail to be drilled, proceed as follows: 7.4.
