PINZBOHR Modular Boring System is composed of a great variety of boring heads, boring kits and all its arbors and accessories. The whole of this system allows boring holes in a range that goes from 6 mm up to 1020 mm.
Rough boring head: fitting two cutting inserts.
Finish boring head: fitting one cutting insert.
Micro boring head: fitting indexable boring bars with one cutting insert (for small diameters).
All of these boring heads are radially adjustable to produce different bore diameters. Rough boring heads are twin radially adjustable by means of a single spindle that moves synchronized and simultaneously the two slide blocks having the insert pockets. Finish and Micro boring heads provide a high precision adjustment through a graduated dial featuring 0.002 mm readout accuracy on diameter.
PINZBOHR arbors are where the boring heads are mounted. These arbors are available in several executions to suit all type of machine spindles: MAS BT 403, DIN 69871, DIN 2080, DIN 69893 (HSK), DIN 228 and DIN 1806 (Morse), DIN 1835 (Weldon), etc. As modular system, PINZBOHR also features reducers, extensions and coolant-feeding extensions.
Each same arbor and extension is available in various lengths, giving to the user the required boring depth with a single arbor configuration.
As accessories PINZBOHR produces adaptors to match PINZBOHR arbors with standard face milling cutter holders, Weldon, Morse and drill chucks (DIN 238).
Chamfering heads with 45º approach angle can be fitted on PINZBOHR arbors and accessories and are axially positioned at the best convenience.
Indexable cartridges are mounted on boring heads and offer several choices of insert geometries and different approach angles (75º, 90º and others).
PINZBOHR features the widest variety of boring kits. Several hole solutions are offered just using one boring head and all its components included in the Bohrstar 54 kit.
One boring kit covers a range that goes from 6 mm up to 210 mm. Various boring kits with partial boring ranges and different insert pocket geometries are available in order to meet with the needs of each user.
The boring head features a high precision adjustment through a graduated dial with 0.002 mm readout accuracy on diameter.
Macrobohr is a lightweight tools line for large diameter boring designed for heavy roughing and precision finishing as well as reverse boring and outside diameter turning.
This Modular Boring System features a boring range that goes from 220 mm up to 1020 mm using different sizes of high strength aluminium plates to reduce the weight of the tool.
Everything is modular! Arbors, boring heads and counterweight are fully interchangeable on all aluminium plates.
