Precision Cutting of Structured Ceramic Molds with Micro PCD Milling Tool
نویسندگان
چکیده
In order to machine micro structured dies and molds made of ceramics, micro milling tools made of poly-crystalline diamond (PCD) are developed. Many cutting edges are ground with diamond wheels. Tool wears of the PCD milling tool are evaluated by cutting spherical molds made of binder-less tungsten carbide and structured surfaces are machined for trial. From the experiments, it is clarified that the tool life of the PCD milling tool is more than 10 times compared with a resinoid diamond grinding wheel and the form accuracy obtained was 0.1 0.3 μm P-V and the surface roughness was 10 nm Rz.

The purpose of this research is to investigate the mechanical and electrical properties of nano structured cordierite. Nano grain size powders were synthesized through mechanical activation by high-energy ball milling of the starting powders containing 34.86 wt% Al2O3, 51.36 wt% SiO2, and 13.78 wt% MgO. Samples were prepared by conventional and microwave sintering at 1390°C. SEM observations il...
متن کاملExperimental Study on Milling CFRP with Staggered PCD Cutter
Carbon fiber reinforced plastics (CFRP) have good physical properties, such as high specific strength and high specific modulus. However, cutting delamination, tearing and burr, etc. often occur in the machining process of CFRP, which results in the uncontrollability of machining surface quality and serious tool wear. In this paper, milling of CFRP with a staggered cutter was carried out, the c...

متن کاملDevelopment of an ultra-precision grinding technique for the production of structured micro-patches on ceramics and tool steel
Ultra-precision grinding using super abrasives such as diamond and Cubic Boron Nitride (CBN) is ideally suited to the production of artefacts in hard or brittle materials such as ceramics or hard metals. These materials are well suited to the production of moulds. Conventional ultra-precision machining techniques such as diamond turning or micro milling are of limited use in the production of t...
