It is a means of altering material surfaces through processes involving adding, removing, or reshaping the metal surface. Three (3) major characteristics can define the surface finish. They are surface roughness, waviness, and lay. The measure of the total space irregularities on the surface metal is known as Surface Roughness.

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. The surface roughness is the measure of the total spaced irregularities on the surface.
In general terms, the abrasive grit size range for grinding wheels runs between 12 grit for rough grinding operations, such as those found in steel mills, and 220 grit for very fine/precision grinding operations. Again, there is no industry standard, but in general terms: Coarse grits run 12 to 24. Medium grits run 30 to 70.
When grinding the sealing surfaces of cast iron, copper, and austenitic stainless steel materials, the grinding pressure is 0.1MPa~0.3MPa; the sealing surfaces of hardened steel and cemented carbide are 0.15MPa~0.4MPa. The larger value is used for rough grinding, and the smaller value is used for fine grinding. 5. Grinding allowance

Standard Resistor Values. Resistors and Capacitors are types of passive electronic components. The basic unit of resistance is the ohm (Ω) and capacitance is Farad. Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 2%, 5%, 10%), along with typically available resistance ranges.

The amount of abrasive bond in the grinding wheel determines its grade or hardness. Hardness is dependent on the grit type, the material being ground, the amount of stock removed, and a number of other factors. Hardness is rated from A-Z, with "A" being the weakest bond and "Z" being the strongest. Harder or stronger bonds in grinding ...
