3D-Druck-Modul

The first series-produced additive manufactured tool in the world: the ACS module with triangular coolant hole ensures maximum cooling through to the edge.

A grooving module with triangular coolant hole – it sounds futuristic but it has already been successfully produced in series – using 3D printing: for the first time, ARNO Werkzeuge and Rosswag Engineering have transformed the possibilities of additive  manufacturing into a standard tool in the grooving sector. This process even allows narrow tools to have two coolant holes with nozzle-shaped geometries and optimised flow characteristics. The bottom hole also ends in a triangular shape to feed coolant through to the edge of the tool flank. This results in longer tool life and shorter chips and it breaks down chips to reduce tool
flank wear. We have already conducted tests with additional side coolant holes. With this tool you are now ready to face future challenges.

Additive manufacturing – ideal for narrow shapes and maximum cooling options with ACS
3D-Druck-Modul mit zwei Kühlkanälen

The 3D printing process allows us to produce coolant holes with flow-optimised hole-geometries where there is actually no space to do so.

Cool all the way down the line – triangular coolant hole
3D-Druck-Modul - Kühlkanal mit Dreiecksform

The coolant hole cooling the tool flank from the bottom ends in a triangular shape. This supplies coolant across the full width of the insert through to the edge and minimises wear.

Cool flanks – ACS4 with side coolant holes already under test

Besides cooling the cutting edges and tool flanks, the insert sides can also be cooled. Prototypes with four coolant holes are  already undergoing trials at the ARNO Test Centre.
