micro grinding development

Apr 20, 2013· Apr 20, 2013· Micro-grinding is a suitable machining process for producing small, chemically stable, and resistant workpieces made of brittle materials such as glass or ceramic. By using small-scaled spindles, micro-grinding is an adequate machining process to be used in small machine tools due to the weight-optimized construction [5, 6]. Currently such ...

Moreover, the development tendency of micro-grinding technology needing to be noted was further pointed out, which includes the ability of machining more engineering materials, compound process ...

May 08, 2018· May 08, 2018· Precision grinding is one of the micro mechanical machining technologies for a wide range of hard non-ferrous materials to fabricate micro structures array. In this paper, a three-axis computer numerical control (CNC) grinding machine tool is designed for the grinding of micro V-grooves array on hard and brittle materials.

Aug 09, 2013· In this case, the effect of micro structure of work material on a removal mechanism involved in the micro grinding process and the pragmatic technologies for making aspherical micro moulds are discussed in detail. The chapter focuses on the development of truing and dressing technologies for micro grinding wheels.

Nov 09, 2016· This paper presents the development process of a new coating method for micro pencil grinding tools (MPGTs). MPGTs, applied for microgrinding, consist of a base body, abrasives, and a metallic bond. The manufacturing process of these microtools presents two challenges.

In addition to reaming of micro-holes, grinding of micro-slots and machining of V-grooves with fabricated PCD tool have been reported [59]. Figure 10.16a shows an …

Jun 01, 2009· The developed micro-tool is utilized to machine hard and brittle materials, such as optical glass, fine ceramics, and tungsten carbide, and for micro-cutting or nano-grinding (Gatzen and Maetzig, 1997). To increase the strength of the proposed micro-grinding tool, the tool shaft is made of tungsten carbide in ultra-fine particles.
