Development and construction of a special apparatus for compacting metal surfaces
The device I developed was used for high-frequency forging of injection moulds and more.
The device, which I call a micro forging device, compacts metal surfaces - even those of already hardened steels - with an impact rate of up to 1000 impacts per second.
In addition to compacting and hardening the surfaces, the surface roughness is drastically reduced.
This effect was used specifically for the finishing and surface refinement of large-format injection moulds. The equipment has a tool holder so that it can be used in any suitable 3D CNC milling machine, for example.
The results surpass polishing of any kind.
