Surface grinding technique: roughing corner/finishing corner. A few years ago, when I got my first surface grinder, Buck suggested a technique that I now use a lot. Case in point: I cut a 50 x 400mm strip of 1.2842 (90MnCrV8 or AISI O2 tool steel) from a 10 x 150 x 400mm plate. The plate was ground parallel both sides (Blanchard) but after I ...
Surface Roughness & Finish Surface roughness - a measurable characteristic based on roughness deviations Surface finish – a subjective term Arithmetic Average (AA) Ra = arithmetic mean value of roughness y= the vertical deviation from nominal surface L m=the specified distance Root-mean-square (RMS) – the square root of the mean of the squared deviation over the
The main uses of grinding and abrasive machining: 1. To improve the surface finish of a part manufactured by other processes Examples: (a) A steel injection molding die is machined by milling; the surface finish must be improved for better plastic flow, either by manual grinding using shaped grinding tools, or by electro-grinding.

What is Surface Finish? Before we go into the surface finish chart, let's understand what surface finish entails. Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay.
