3.10) Spiral bits Brush ø h APED... FIG. 1 APE... L max ø L max FIG. 2 FIG. 28 – CHANGING THE BRUSHES – – – – Hardness of the material to be drilled. Thickness to be drilled. Stability of the drill clamp and correct assembly of the cutter/bit. Suitable lubrocooling (lubrication/cooling) to keep the temperature of the tool low so as not to compromise the efficiency of the cutting edges, whilst at the same time facilitating the removal of the swarf.
4. COOLANT UNIT TYPE SR5000 (Ref. to Fig. 3) The type SR5000 coolant unit consists of a tank complete with tube and maximum pressure valve (01), fitted with a pump device for pressurisation, which must be connected to the attachment (35) on the drill by means of its quick-coupling (03).
• The drill is equipped with a coolant attachment valve (35) and a vent valve (17) 11. MAINTENANCE servicing or maintenance, stop the motor and disconnect the Before plug from the electric source. After first 10 operating hours, proceed with sump oil change, as follows: (Ref. to Fig. 26a and 26b) – 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 § 11.1.2).
10. STORING THE DRILL 5. SPINDLE ADVANCE LEVER (Ref. to Fig. 6) When work has been completed, store the drill by proceeding as follows: The spindle is advanced by moving the lever (36) (see Fig. 6a). The lever is fitted with a release pawl (39) which, when pressed, renders it independent of the hub and hence the spindle; the operator can therefore easily vary the angular position of the lever without movement of the spindle (Fig. 6). 10.
For clarity the drill is not shown in the figures 02 6. PREPARING THE RAIL DRILL always the power supply when servicing the drill: DISCONNECT before removing the broach cutters, spiral bits, positioning templates etc. 6.1) Assembling broach cutters (Ref. to Figs. 8-11). 6.1.1) Insert the guide 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 is necessary to use an APE... adaptor the bit must first be fitted in the corresponding APE adaptor and locked with the appropriate grub screw, then the DPE spacer inserted. Note: Adaptors type APED… (e.g. APED 135/165) 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.
9. SPA... POSITIONING PLATE 7. RAIL DRILL TYPE LD-2E ; LD-2E-110 ; LD-4EF 9.1) Instruction for drilling close to rail heads Code n. LD-2E ; LD-2E-110 ; LD-4EF each cover a basic drill (see page 1) complete with the moving arm device DBG-F2 for clamping to the rail web and the track fittings (Ref. to Fig. 12).
7.1) Assembling end pieces TDB 1, TDB 6 and TDB 3 end pieces of the DBG-F2 device, with moving arm, have been designed for adaptation to the different operating conditions on rails and track fittings; their assembly is shown in Fig. 13. • When assembling the TDB 3 end piece ensure that the positioning pawl is pointing downward in relation to the bolt.
8.1.5) ONLY FOR LD-4EF DRILL Set the motor speed, by means of the selector switch under the automatic switch (see Fig. 17e), in correlation to the diameter of the hole to be. We suggest to use the standard speed (280 rpm) for holes smaller than ø 28 mm and the lower speed (250 rpm) for holes between dia 28 and 40 mm inclusive. 7.
7.4) Clamping to the rail web (Ref. to Fig. 16) 8. DRILLING (Ref. to Figs. 17-18) The drill has a rapid rail engagement/release mechanism and specially shaped positioning templates for each rail type which facilitate precise and certain location of the part to be drilled. To fully exploit the special features of the engagement device, we recommend calibrating it to the rail type to be drilled as follows: 7.4.1) Withdraw the spindle shaft (07) completely by means of the lever (36). 7.4.
