8.2 Installation

Cleaning

Before installing the machine, clean with care all its components and the area where it will beinstalled. Install the machine in a building having a flat and sufficiently strong floor.

1. The area for the machine and the spaces around it must be enough to work safely.Recommended area: 2.5 m X 2 m.

2. Secure the machine to the floor (Figure 27).

First insert the fastening screws into the concrete of the foundation or support base, checkingthe correct positioning with respect to the holes present on the base of the machine. Oncethe cement has hardened, install the machine making sure it is positioned horizontally.Finally, tighten the fastening nuts on the base of the Drill.

9 OPERATION


The Floor Drilling Machine must be used only for performing envisaged processes, withsuitable tools.

Risk of Crushing

Before using the machine, make sure that the base is fixed rigidly to the floor to preventmovement or loss of stability.


The Floor Drilling Machine should be used only by skilled, trained staff: the machine is to beused only after having read and understood this manual.

Risk of injury

The workpiece must be firmly fixed to the work bench (with the vice) while operating themachine. The workpiece must never be held in place with your hand.

9.1 Preliminary checksMake sure that the tool holder spindle is securely fastened. Use only appropriate tool holders.

Clean the machine and lubricate where required (see chapter "Maintenance"), to turn themachine starting from the lowest speed up to the maximum, making sure that everything isworking properly.

9.2 DrillingThis model is designed for manual operation only.

1. Choose an appropriate tool for the next process and insert it between the jaws of the spindle.2. With the wrench supplied, secure the tool by tightening the spindle as shown in Figure 28.

Mounting the tool

Make sure that the tool is properly and securely assembled before starting the machine.

3. Set the rotation speed of the spindle (and thus of the tool) as a function of the operationto be performed, by displacing the Drill's drive belts as indicated in paragraph 5.2.

4. Secure the workpiece on the work surface by tightening it with the spindle.5. Adjust the height of the work surface, as well as its inclination.6. Close the spindle's interlocked guard protection.7. Turn on the drill and start the rotation, moving the selector switch (ref. 5 in Figure 6) to

the “DRILLING” position, then press the start button for clockwise spindle rotation (ref. 2in Figure 6).

8. Lower the spindle using the hand wheel for vertical displacement and drill the hole (seethe Figure 29).

Figure 29 - Lowering the spindle.

Drilling depth

Check drilling depth on the graduated scale on the spindle feed hand wheel.

9. When finished, release the wheel.

9.3 TappingTo successfully carry out the tapping, proceed as follows:1. Choose an appropriate tool for the next process and insert it between the jaws of the

spindle.2. With the wrench supplied, secure the tool by tightening the spindle as shown in Figure 28.3. Set the rotation speed of the spindle (and thus of the tool) as a function of the operation

to be performed, by displacing the Drill's drive belts as indicated in paragraph 5.2.4. Secure the workpiece on the work surface by tightening it with the spindle.

5. Adjust the height of the work surface, as well as itsinclination.

6. Close the spindle's interlocked guard protection.7. Set the tapping depth by using the appropriate graduated

ring and the travel limit for reversal of the automaticrotation (Figure 30).

Figure 30 Graduated ringand travel limit

8. Move the selector (ref. 5 Figure 6) to the “TAPPING” position, then press the start buttonfor clockwise spindle rotation (ref. 2 Figure 6).

9. Gradually lower the spindle until it comes into the contact with the workpiece, and thencontinue to advance executing the threading, once the travel limit has reached therotation inversion micro switch, the tip will stop and reverse rotation.

10. Once rotation has been reversed make sure the tool is exiting the workpiece properly,without applying any force on the feed handwheel, when the threading has just beenmade, make sure the tool exits the workpiece.

Tapping

During tapping operations: Do not perform the work at a high speed; Do not exert too much pressure on the spindle lowering handwheel during the

execution of the tapping; Do not force the tool when exiting the workpiece;

Lubrication

During tapping operations the tool and the workpiece should be kept constantly lubricatedwith oil, in order to avoid excessive overheating of the parts, with the consequent loss ofprecision and cleanliness of the threading.

The reversal in the direction of spindle rotation can be performed manually by theoperator, by stopping the machine at the end of threading via the button (ref.4Figure 6) and by starting anti-clockwise rotation via the button (ref.3 Figure 6).fer
