Characteristics of Fine Grinding: The abrasives used for Fine Grinding arefixed or bonded, eitherglued onto a paper or mixed with resinor are added onto a rigid grinding surface. The goal of Fine Grinding is to reduce damage and surface roughness of samples to a degree that is suitable for polishing.
Grinding is the first step of mechanical material removal. Proper grinding removes damaged ordeformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.
Jan 22, 2014· Highly magnified schematic view of a cross section through a sample during the grinding process. Grinding servestwo purposes,first to remove micro-shattering caused by cutting (1 and 2),second to prepare the surface for polishing (3 and 4). With consecutive smaller grits you have to remove the scratches left by the previous grit.

Sep 01, 2014· Let’s explore propersample grindingand positioning for OES metal analysis in Spark Mode using high purity argon gas. Samples must be ground to a flat, evensurfaceusing a stationary belt sander and an aluminum oxide belt. The lines should be evenly spaced and moving in a parallel direction.
Normally, the first work step on the sample is surface grinding. This ensures that a flat surface is created on which all components of the surface are, if possible, on one level. For this step it is preferable to use fixed grinding particles with a large grain in order to achieve a high, consistent removal rate, short working times and maximum flatness.

8.5 As with the last wheel, keep thesampleon the same location on the wheel throughout this process. 8.6 Stay on this wheel until all of the new scratches are running in the same direction. 8.7 Repeat rinsing, drying, and turning of thesample1/4 turn throughout all of thegrindingwheels.
The purpose of the grinding step is to remove damage from cutting, planarize the specimen(s), and to remove material approaching the area of interest. It is important to note that it is possible to create more damage in grinding than in sectioning.
