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

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
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 calliper 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 adjustment screw.
Setscrew in the valve is used for setting the length of time the
3
hold-down clamps remain in position for after drilling (drilling
hole lines only).
Setscrew adjusts drilling penetration rate. This setting 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
Check the setting by making a test drilling.
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
valves . Check the setting by making a test drilling.
