Long Service Life Sasib Cigarette Pocket Mould For Packing Machine
Pocket is a moulding part of cigarette packing machine that helps shape a cigarette packet.
1. Consumables
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.
Grinding wheels are consumables, although the life span can vary widely depending on the use case, from less than a day to many years.
2. Material Hardness
The abrasive aggregate is selected according to the hardness of the material being cut.
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.
Aluminum oxide (A)
Silicon carbide (S)
Ceramic (C)
3. Grain Size
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).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.
