Lapping performance of mixed-size agglomerated diamond abrasives in fixed abrasives pads

Diamond and Related Materials, 2021
Abstract Ultra-fine diamond grains are used to prepare agglomerated diamond (AD) abrasives that are, in turn, applied to make fixed agglomerated diamond abrasive (FADA) pads. The as-prepared pads demonstrated very low removal efficiency along with a poor processing stability，which limits the applicability of ultra-fine diamond grains in fixed ...

Hybrid tool with both fixed-abrasive and loose-abrasive phases

CIRP Annals, 2015
Abstract The use of multiple pole tips in a Magnetic Abrasive Finishing (MAF) system allows for shorter processing times, but it can also exacerbate any difficulties encountered in abrasive insertion and distribution. This paper proposes a hybrid tool that initially works as fixed abrasive but works as loose abrasive once the abrasive binder ...

A semi-fixed abrasive machining technique

Journal of Micromechanics and Microengineering, 2009
This paper proposes the technique of semi-fixed abrasive machining to reduce or eliminate the surface defects caused by large abrasive grains and improve the efficiency of ultra-precision processing. The method of semi-fixed abrasive machining is described, and a semi-fixed abrasive plate (SFAP) is manufactured.

Aspheric surface finishing by fixed abrasives

The International Journal of Advanced Manufacturing Technology, 2006
This paper presents a method for the finishing of aspheric surfaces using fixed abrasives. The strategy is to remove a specified amount of material from the surface. The method assumes concentric tool paths perpendicular to the axis of the surface. The key parts of the method are: (1) efficient computation of the material removal profile for each tool ...

Effect of Abrasive Particle Size on Lapping of Sapphire Wafer by Fixed Abrasive Pad

Key Engineering Materials, 2018
The choice of abrasive particle size is crucial to improve the lapping efficiency and surface quality in lapping of sapphire wafer by fixed abrasive (FA) pad. A model for the penetration depth of a single abrasive is developed with fixed abrasive pad.

Research on Subsurface Damage After Abrasives and Fixed-Abrasive Lapping of K9 Glass

Key Engineering Materials, 2011
Fixed-abrasive lapping (FAL) is a new machining technology and is adopted to manufacture hard brittle materials to obtain the high surface quality. In the same machining condition, K9 glasses are lapped by abrasives and fixed-abrasive, respectively. Two grain sizes of diamond abrasives are adopted in every lapping means.

Manufacturing of Fixed-Abrasive Polyethylene Wire Saw

Applied Mechanics and Materials, 2011
Fixed-abrasive diamond wire saw is widely used for slicing semiconductor materials. In this paper, a novel manufacturing method is studied by using polyethylene wire to replace the traditional metallic core wire. A new coating device of ultraviolet-curing for rapidly making diamond wire saw is developed.
