In wet stirred milling of Al-doped TiO2, sodium hexametaphosphate (SHMP) is used as a small molecule dispersant to improve performance. both acidic and basic conditions, SHMP interacts strongly with TiO2 remains stable during milling. Considering the apparent true particle breakage performance, at pH 10.3, optimal dosing concentration was 0.16 wt% (0.33?, sub-monolayer coverage), which consiste...

Abrasive machining is a widely employed finishing process for different materials such as metals, ceramics, glass, rocks, etc to achieve close tolerances and good dimensional accuracy and surface integrity. High efficiency abrasive machining is one of the important techniques of advanced manufacture. Combined with raw and finishing machining, it can attain high material removal rate like turnin...

The actual grinding result of ceramics has not been well predicted by the present mechanical models. No allowance is made for direct effects of materials microstructure and almost all the mechanical models were obtained based on crystalline ceramics. In order to improve the mechanical models of ceramics, surface grinding experiments on crystalline ceramics and non-crystalline ceramics were cond...

The surface of zirconia may be damaged during grinding, influencing the mechanical properties of the material. The purpose of this study was to compare the flexural strength of zirconia after different grinding procedures. Twenty bar-type zirconia specimens (21 x 5 x 2 mm) were divided into 4 groups and ground using a high-speed handpiece or a low-speed straight handpiece until the bars were re...

This work presents a system of measuring grinding forces in precision applications. Several experiments demonstrate the performance in monitoring diamond wheel dressing, detecting workpiece contact, and process monitoring. The system appears promising for monitoring precision wafer grinding since this approach provides excellent sensitivity, high signal resolution, and good bandwidth. INTRODUCT...

Surface roughness is a significant parameter which determines the efficiency of optical components. Surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. It is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. In this study, a cup diamond wheel (D64) is used in grinding pr...
