PINZBOHR / FINISH BORING HEADS

finish boring head adjusting accuracy

Precision boring head allowing fine finish boring operations.

12 different boring head sizes cover a boring range that goes from diameter 24 mm up to 500 mm.

High precision adjustment through a graduated dial featuring 0.002 mm readout accuracy on diameter.

Pre-load device between boring head’s body and slide block to prevent movement when tightening the locking screw for working. This pre-load device also maintains the displacement perpendicularity with the rotation axis.

Robust integral insert pocket design for boring heads sizes 22, 27, 32, 42 and 54.

Robust interchangeable insert cartridges design for boring heads sizes 68, 85, 100, 200, 300, 400 and 500.

Boring heads and cartridges available in 75º, 90º and other cutting approach angles.

Boring heads and cartridges available in different insert geometries (CC.., CN.., TC.., TP.., WC.., etc.).

All cartridges also have their own radial adjusting screw for individual setting of them over the boring head's slide block.

Change to different insert style or cutting approach angle by simply exchanging the cartridge.

Boring heads maintain a solid design from small diameter boring heads up to the large diameter ones. Other designs increase in diameter based on extended bridges that do not provide the same rigidness.
