Basic Research for the UV Fixed Abrasive Lapping Plate

Applied Mechanics and Materials, 2013
The traditional lapping procedure is based on a slurry process. This paper describes the development of a novel fixed abrasive lapping plate (UV-plate) and investigates the basic property of ultraviolet-cured resins. The primary lapping experiments are carried out. Experimental results show that the lapping process performed with UV-plate significantly

Lapping and Polishing of Sapphire Wafer with Fixed Abrasive Pad

Advanced Materials Research, 2014
The processing technology of sapphire with a high material removal rate a good surface quality is critical for its applications. The experiment of sapphire lapping and polishing was carried out by using three different fixed abrasive pad (FAP). Their material removal rate (MRR) and surface roughness (Ra) were measured and analyzed.

Fixed Abrasive Lapping and Polishing of Hard Brittle Materials

Key Engineering Materials, 2010
Fixed abrasive lapping and polishing (FALP) is a new machining technology and was adopted to manufacture hard brittle materials and obtain the high productivity because of fixed abrasive. The preparation process of fixed abrasive pad (FAP) was described. FALP of K9 glass, mobile panel glass and Si were investigated with fixed 5-10 µm diamond abrasives.

Research on Subsurface Damage of Lapping Sapphire with Diamond Fixed Abrasive

Key Engineering Materials, 2020
The depth of surface/subsurface damage layer is the key index of surface quality of sapphire. In this paper, that depth model of the surface/subsurface damage lay characterized by the crack length was established according to the mechanical theory of indentation fracture.

Subsurface damage of fused silica lapped by fixed-abrasive diamond pellets

Applied Optics, 2014
Minimizing subsurface damage (SSD) is in high demand for optics during grinding, lapping, and polishing. A fixed-abrasive diamond pellet (FADP) has been validated as a potential tool in fast lapping and polishing of hard optical materials. This study inspects and measures the SSD of fused silica developed in lapping and microlapping by FADPs tool ...

Manufacturing of a Sintered Cast Iron Lapping Plate with Fixed Abrasives and its Lapping Abilities

CIRP Annals, 1981
This research work aims to provide a new lapping plate with fixed abrasives by powder metallurgy. The abrasives having excellent lapping ability like diamond and cubic boron nitride are premixed with the matrix cast iron powder. A lapping plate including abrasives in its surface layer is compacted and sintered at 1413 k in the ammonia cracking gas ...
