Hole reaming from precision grade IT4!

In August 2023, we started a close cooperation with the University of West Bohemia (ZČU) and the Regional Technological Institute (RTI) in Pilsen on research and development of reamers with CBN cutting edges.

Introduction News Hole reaming from precision grade IT4!

Development project

The aim of the project is to achieve a stable production process for reaming high-precision holes from precision IT4 in the production of ductile and grey cast iron components.

An example from practice

In the production of many components, honing technology, i.e. the cross grinding of holes on special honing machines, is currently used in the finishing of high-precision holes. This means that production operations on a single component must be carried out on several machines. The aim of the project is to enable the production of a component to be carried out on a single universal fully automated CNC machine, thereby significantly increasing production productivity at significantly lower production costs.
