FIG. 16 – POSITIONING OF THE DRILL

8.4) Clamping to the rail web (Refer to Fig. 16)

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:

8.4.1) Withdraw the spindle shaft (07) completely by means of the lever (36).

8.4.2) Insert the threaded bush (39) of screw (11) into its seat (A) in the mobile arm (17) (see

detail in Fig. 16); use the hand-wheel (12) to completely open the mobile arm.

8.4.3) Place the drill on the rail at the point to be drilled and clamp it by tightening the

hand-wheel fully down (12): the positioning template will automatically position the cutter or

drill bit in line with the designated axis; if precise positioning is necessary to the longitudinal

track axis, use the reference pin (01).

8.4.4)

For rapid drill release, simply back-off the hand-wheel (12) by approximately two

complete turns, and while supporting the drill by its grip (09), pull the hand-wheel towards

you. The threaded bush (39) will disengage the seat (A) in the mobile arm (17) which will

open automatically, freeing the drill.

In this way, the operator can rapidly remove the machine from the rail in case of danger,

or move on to drill another hole.

Thus, the next rail engagement operation will be considerably simplified:

after positioning the drill at the point to be drilled, simply push the hand-wheel forwards

so that the threaded bush engages the seat (A) of the mobile arm. Now, a few turns on the

hand-wheel will be sufficient to engage the drill correctly on the rail.
