Fine Grinding of Silicon Wafers: Grinding Marks

2008-6-3 · This paper presents an investigation of grinding marks in fine grinding. The investigation covers (1) nature of grinding marks, (2) factors that have effects on grinding marks, and (3) approaches to reduce grinding marks. Varying chuck speed during grinding operation is shown to be a very effective approach to reduce grinding marks.

Quantifying the energy efficiency of fine grinding ...

In previous publications, we have described how the size specific energy (SSE) can be calculated to predict the energy required to generate new minus 75 µm material. However, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 µm, clearly we require a finer marker size. If we do this, we also need a way to compare results that

A Fine Grind | Cutting Tool Engineering

2011-9-1 · Grinding thin-wall tubing is an M&S specialty. The company recently ground 25-gauge stainless steel hypodermic tubing, 0.030" in diameter and 1" long, to a wall thickness of 0.0006". The tubes required a centerless infeed operation because the OD had a step; a small portion of the diameter remained at 0.030", but the rest was ground to 0.025".
