Surface finishing Internal diamond burnishing for surface finish below Ra 0.3 µm
Reaching a good surface finish has always been challenging, especially when it comes to internal machining. It’s even more difficult when the holes are deep and narrow which calls for a tool with a long overhang. To master also those processes MAQ is introducing its diamond burnishing line.
With its new product line, MAQ’s internal diamond burnishing solution can effectively reach a surface finish at Ra 0.3 µm, even with tools at 15xD setup, see the above example of 25 mm product series.
The diamond burnishing process is known for its capacity of creating a shiny surface finish with reduced friction, combined with the advantage of a hardened surface layer for wear resistance and a dense surface topology for its chemical resistance. Mounted on a MAQ STMD turning tool holder, the burnishing tool will bring all these advantages to a turning machine, even for the internal turning operation, without even changing the setup of the workpiece clamping.
