Drilling Into Epoxy-Resin Models - Renfert Top spin Mode D'emploi

The drill hole depth is set exclusively by adjusting the depth stop
(see section 5.2).
⇒ Switch unit off and disconnect from the power supply.
⇒ Remove the drill bit (see section 5.5 "Changing the Drill").
The chuck should not be removed; this can be used as a guide for
the Allen key.
⇒ Press the spindle lock (7, Fig. 1) and turn the drilling spindle until
the spindle lock clicks into place.
⇒ Continue to press the spindle lock.
⇒ Using the supplied Allen key (10) turn the drill stop back until the
drill bit tip is at least 5 mm below the drill table surface.
♦ A single turn adjusts the drill stop by 0.45 mm.
⇒ Check the setting.
- Insert the drill; it is not necessary to tighten.
- Press the table down to the marked groove (23) in the laser arm.
- The drill bit tip must not protrude above the table level.
⇒ If necessary, correct the setting.
If, due to frequent adjustment, the drill stop is no longer sufficiently secure, the drill slips down
in the chuck during drilling or the drilled holes are no longer the required depth, the threaded
pin can be exchanged for the replacement included in delivery.

Drilling into Epoxy-Resin Models

⇒ Insert a conical acrylic drill (see section 5.5).
⇒ DO NOT put the dust hood on (11, Fig. 1) on.
⇒ If necessary, adjust the drill stop (see section 5.6).
⇒ Set the drill depth (see section 5.2).
⇒ Carry out trial drilling.
⇒ If necessary, re-adjust the drill depth (1 click = 0.1 mm).
Remove the drilled shavings from the drill on a regular basis.
When drilling into acrylic or epoxy resin, if the drill is pressed down too quickly, it may become
stuck and stop.
Find the correct speed through trial and error.
If the drill becomes stuck because the drilling table was pushed down too quickly:
♦ the drilling motor will switch off
♦ the operating display will blink (3, Fig. 1) briefly
♦ the drilling motor is switched back on after 1 second with a low rpm, until the drilling table is back in
its original position.
If the drill bit is not released after this procedure, continue as follows:
⇒ Disconnect from the power supply
⇒ Press spindle lock (7, Fig. 1) and turn base plate until the spindle lock clicks into place.
⇒ Continue to press the spindle lock.
⇒ Turn the drill bit slightly backwards and then slightly forwards to release from the base plate.
