Recent Developments in Desktop-Sized Machine Tools

Abstract

The miniaturization of components and the functionalization via micro structures demands for flexible and economic manufacturing processes. Micro machining, i.e. micro milling and micro grinding can meet these requirements. In this paper, desktop-sized machine tools and their components that were developed at our institute are presented. With those machine tools, micro tools can be machined and used in one clamping, allowing for increased machining quality. Grooves milled with such machine tools achieve a bottom surface roughness below 10 nanometer.

Is dropwise condensation feasible? A review on surface modifications for continuous dropwise condensation and a profitability analysis

“…Other top down approaches include micromilling and microgrinding [60] , [61] , abrasive blasting [62] , and femtosecond laser macromachining [63] , [64] . The latter is also known to produce hierarchical self-organized laser-induced periodic surface structures (LIPSS; [65] , [66] ) or cone like protrusions (CLP; [67] ), which are known to be hydrophobic.…”

Tribological Properties of Alkyldiphenylethers in Boundary Lubrication

“…As machines have been increasingly downsized in recent years, demand for smaller, lighter, higher-speed, and maintenance-free moving mechanical components has grown [1][2][3]. Lubricants used in such components generally serve under severe conditions, such as high temperature, high speed, and high load.…”
