Technical features:
Each drilling unit has a suction pipe for chip extraction, in addition, there is a recess in the clamping table for the chip fall, a collection container with a connection diameter of 120 mm for the suction hose is screwed to the recess on the underside of the table, feed movement of the drilling spindles pneumatically controlled – feed speed and feed pressure or the clamping pressure of the hold-down punches can be adjusted by handwheels – the feed path of each drilling spindle is individually mechanically adjustable.
Optionally, each drilling unit can be equipped with a multi-spindle drill head with up to three drilling spindles (this means 24 holes in one work cycle). Reading of the set pneumatic pressures on analog pressure gauges. Pneumatic workpiece clamping electronically monitored, drilling cycle triggered by foot pedal and two-hand release
