The development of novel micro parts for several applications has grown rapidly over the last years. In most cases, it is possible to manufacture micro parts by means of micro machining. However, mechanical material removal processes make use of large-scale machine tools with dimensions that exceed the small-sized parts (usually up to 10 mm) by a factor of more than 1,000. This paper shows advances in the combination of micro and ultra-precision machining processes in order to meet the strict micro parts’ requirements and a novel concept for a micro grinding module, which can be integrated into small-scaled machine tools.

The microstructuring of embossing rollers offers an economic and productive production tool for molding of large-area plastic films with functional and optical properties. Due to ultraprecision diamond machining processes a wide spectrum of microstructures in combination with a high manufacturing flexibility can be produced for optical, fluidic and mechanical applications. Both, the microstructuring of embossing rollers by ultraprecision diamond machining as well as the following molding process of plastic films exhibit a high potential for innovative applications in industrial and consumer products.

In modern industry optical technologies stand for a leading innovative power influencing all sectors of economy and, thus, representing important factors within economic competition of coming markets. Regarding the manufacture of complex consumer optics the development of reasonable and flexible mass production processes is one of the dominant priority actions and ultra-precision machining technologies play a key role within this challenging task.
