Title: Hartmut Rieger: Innovator in Metal Shaping Processes

Introduction

Hartmut Rieger is a notable inventor based in Boxberg, Germany. He has made significant contributions to the field of metal shaping processes, holding two patents that showcase his innovative approach to cooling lubricants.

Latest Patents

Rieger's latest patents include a metal shaping process that utilizes a novel two-phase cooling lubricant system. This process involves the application of a first cooling lubricant, which is an oil or a first emulsion with an oil content of at least 10 wt. %, to the workpiece at the tribo-zone. Simultaneously, a second cooling lubricant, which is oil-free or an oil-in-water emulsion with less than 10 wt. % oil content, is applied adjacent to the tribo-zone. The design allows for the use of a two-component nozzle to supply both cooling lubricants effectively. Additionally, he has developed a process for preparing a stable cooling lubricant emulsion, which involves emulsifying an oil component in water with the help of an emulsifier. This stable emulsion can be utilized in a wide range of metal cutting applications.
