Centobohr precision rotary inserts
Koyemann Centobohr precision finishing tools are stable, adjustable tool for bore finishing, which can be fitted to any boring bar with a square tool mount. They are fitted with interchangeable tool holders for indexable inserts. The Centobohr tool holders are available both in a variant for through bores, in which the indexable insert is positioned axially behind the front of the boring bar, and in angled shapes, with the insert positioned axially ahead of the boring bar, so the bores can be machined up to shoulders or right to the end of the blind holes.
The Koyemann Centobohr is used
for close-fit bores in diameters from 32 mm to 700 mm
for push and pull operation
for through holes
for shoulder and blind bores
on machining centres, boring mills and and milling machines
The principal features of the Centobohr are
simple adjustment of the Centobohr precision finishing tool by turning the scaled spindle
high precision with stable positioning of the Centobohr bit by 0.01 mm per gradation
particularly large range by moving the whole Centobohr cartridge in the boring bar
low tool costs, as the Centobohr precision finishing tool can be used in any normal tool holder in boring bars and heads
