Setting Drilling Depth; Drilling Penetration Rate (End-Position Damping) - Hettich BlueMax Mini Modular Instructions De Service

Setting up

Setting drilling depth

The stop limits downward drilling-stroke movement.
The drilling stroke can be selected to suit any panel thickness.
To do this, undo locknut in stop
2
required direction.
Always re-tighten the locknut to avoid differences in drilling
depth.
Afterwards, carry out a trial drilling and check drilling depth
using a caliper gauge.

Drilling penetration rate (end-position damping)

The drill lowering rate can be limited so as to obtain good
drilling results.
The rate is reduced just before the drill bits reach the panel.
Lower end-position damping is adjusting using setscrew
the stroke cylinder at the rear of the machine.
Drilling penetration rate can be reduced or increased by
turning the setscrew.
Setscrew in the valve is used for setting the length of time
3
the hold-down clamps remain in position for after drilling
(drilling hole lines only).
Setscrew adjusts drilling penetration rate. This setting
7
needs to be made when changing over from pushbutton to
foot valve.
When operating the machine with the foot valve, drilling
penetration rate is adjusted at setscrew
Carry out a test drilling to check the setting.
Drill overrun
The drill overrun can be adjusted. This is factory-set. To
change the drill overrun, turn the screw on the throttle non-
return valve . Check the setting by making a test drilling.
