Tool assembly
Tools with
ABS®
connection
All existing ABS32 tools for precision machining applications
can be used in conjunction with the MicroKom®
hi.flex
precision drilling system.
ABS® tools are clamped by means of securing screw
6
.
“Fasten” securing screw

to prevent it from falling out.

Tools with parallel shank
Flexibility in projection length: boring bars B05 support vari-
able clamping lengths. Boring bars can be clamped with a
maximum projection of 9 mm (clamp using both securing
screws
6
and
7
). Boring bars with parallel shank: DIN
1835-B and E only suitable provided certain conditions are
met; DIN 1835-A possible.
During tool assembly, the indexable insert must be pointing
towards the cutting edge illustrated here.
Maximum permissible rotation speed = 17,500 rpm
Prerequisites – valid with slide centred and with boring bar
B05 20100.
Coolant:
The head features an internal coolant supply. With
the use of boring bars and the serrated body, the coolant
is supplied centrally through the body of the boring bar.
From a diameter of 63 upwards, the coolant-diverting stop-
per must be fitted. The stopper prevents the coolant from
escaping from the center and diverts the coolant internally.
Clamp the stopper separately using both securing screws
6
and
7
.
The use of the central coolant supply is mandatory. The
cooling lubricant helps to ensure optimum chip formation
and chip removal.
The coolant pressure should not fall below the minimum of
5 bar. Increasing the coolant pressure to 10-20 bar improves
the machining process and is therefore highly recommended
where possible.
