Cost savings up to 40%. Having the right abrasive is not enough. All components involved in the grinding process have to be perfectly adjusted as well. Cost savings of up to 40% have proven to be realistic. They can be achieved by reducing the amount of rejects, reducing cycle times and the amount of machine down-times.
Small wheels of 25mm diameter cost up to 10$ for conventional abrasive and for diamond up to 200$.; Large wheel of 500mm diameter and 250mm width, the cost is about 8000$ to 20000$.; Life of Grinding Wheel. When a grinding wheel is applied to the workpiece, the sharp edges of the abrasive grains which are cutting, will, in the end, lose their cutting effect and become dull.
Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. A wide variety of machines are used for grinding: Hand-cranked knife-sharpening stones Handheld power tools such as angle grinders and die grinders Various kinds of expensive industrial machine tools called grinding machines Bench grinders Milling practice is a large and diverse area of manufacturing and
