GD 121 AF Low Honing Alloy Grinding Wheel MK8 Cigarette Machine components

GD 121 AF Low honing Alloy Grinding Wheel

Alloy Grinding Wheel is a component of cigarette making machines to sharpen cutting knives.

Specs

1. Consumables

Grinding wheels are consumables, although the life span can vary widely depending on the use case, from less than a day to many years. As the wheel cuts, it periodically releases individual grains of abrasive, typically because they grow dull and the increased drag pulls them out of the bond. Fresh grains are exposed in this wear process, which begin the next cycle. The rate of wear in this process is usually very predictable for a given application, and is necessary for good performance.

2. Material Hardness

The abrasive aggregate is selected according to the hardness of the material being cut.

Aluminum oxide (A)

Silicon carbide (S)

Ceramic (C)

Diamond (D, MD, SD)

Cubic boron nitride (CBN)

Grinding wheels with diamond or CBN grains are called superabrasives. Grinding wheels with aluminum oxide (corundum), silicon carbide, or ceramic grains are called conventional abrasives.

3. Grain Size

From 10 (coarsest) to 600 (finest), determines the average physical size of the abrasive grains in the wheel. A larger grain will cut freely, allowing fast cutting but poor surface finish. Ultra-fine grain sizes are for precision finish work. generally grain size of grinding wheel are 10-24(coarse),30-60(medium),80-200(fine) and 220-600(very fine).
