3 These axial forces preload the contact surface between the flange faces of the coupled components with high axial pressure for ample support against lateral loads. It can also dampen TOOL ORIENTATIONThe locating pin guarantees repeat positioning between components at all arbors, extensions and reducers are shipped complete with coupling SCREWCOUPLING SCREWBORING HEADARBORP inzbohr BORING system features a wide range of rough and finish BORING heads covering diameters from 6 mm up to 500 are three types of BORING heads:All these BORING heads are radially adjustable to machine different arbor designs are available mating the most popular spindles.

4 Extensions and reducers compliment the MODULAR system to offer a complete flexibility across the system features a wide range of ISO standard insert pocket choices and indexable taper screw design allows tools to be changed without removing from the spindle. Main components are manufactured from Nickel-Chrome alloy steel, heat treated to 58-60 ground slides ensure accuracy of adjustment throughout the heads working BORING heads (two inserts) with synchronized BORING heads (one insert) with graduated precision dial adjustable BORING heads (for small diameters) fitting indexable BORING bars with also graduated precision dial )2)3) TO THE INDEXADVANTAGESP ractical MODULAR system: different types of BORING heads with arbors, extensions, reducers allow price reduction when tooling up the range of diameters.

6 Heads do have a read out precision of mm .For diameters from 24 mm up to 220 mm, finish BORING heads are available in two choices of angle approach: 75 & 90 . And feature various insert pocket geometries to BORING heads with two cutting edges do have synchronized adjustment. This advantage means not to waste time in presetting the two cutting edges for a balanced cut (diameter adjustment can be set in the machine directly with a caliper).For diameters from 24 mm up to 220 mm, rough BORING heads are available in two choices of angle approach: 75 & 90 .

MICRO BORING heads fit the standard PINZBOHR arbors size 27, 32 and 42 (recommended in extra short execution).Graduated dial and readout precision of mm.
