The sea urchin tooth is a remarkable grinding tool. Even though the tooth is composed almost entirely of calcite, it is used to grind holes into a rocky substrate itself often composed of calcite. Here, we use 3 complementary high-resolution tools to probe aspects of the structure of the grinding tip: X-ray photoelectron emission spectromicroscopy (X-PEEM), X-ray microdiffraction, and NanoSIMS....

In this paper, an attempt has been made to characterize the surface texture generated, during Magnetic Field Assisted Abrasive Finishing (MFAAF) of SS316L material. The changes in surface texture generated are studied by using surface roughness profiler, Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). The deep cutting marks left by grinding process have been removed and re...

The profile of a 10 mm wide and 3μm deep grinding imprint is as unique as a human fingerprint. To utilize this for fingerprinting mechanical components, a robust and strong characterization has to be used. We propose a feature-based approach, in which features of a 1D profile are detected and described in its 2D space-frequency representation. We show that the approach is robust on depth maps a...

The grinding process consists of an abrasive contact between a moving workpiece and a wheel in rotation [1]. Because of the grinding power converted into heat at the interface, high temperatures can appear that can lead to thermal, mechanical or metallurgical consequences. Each of these effects has been fully related in literature by authors. Guo presents a good review of surface layers (dark, ...

This article discusses the recent developments in grinding of advanced materials. Eighty-four journal papers published recently are briefly introduced. The topics are advances in grinding of brittle materials, grinding of silicon, dressing/truing of grinding wheels, grinding fluids, grinding of mirrors and vibration-assisted grinding, measuring/ monitoring of grinding, optimization of grinding,...

Ceramic grinding, which in this paper is defined as a method of using ceramic materials grinding media, favored by many processing plants an emerging high-efficiency and energy-saving method. This investigates the effect slurry mass concentration on characteristics magnetite taking feed secondary ball mill for research object. The study results show that significantly affects magnetite, especia...
