As a core tool in grinding, the selection of the grinding wheel directly affects the processing quality, efficiency, and cost.
I. Introduction
As a core tool in grinding, the selection of grinding wheels directly affects processing quality, efficiency, and cost. Therefore, when selecting grinding wheels, multiple factors need to be comprehensively considered, including the characteristics of the workpiece, the performance of the grinding wheel, and other important factors. This article will elaborate on these factors to help readers make more reasonable and accurate grinding wheel selection decisions.
II. Workpiece
Material and Hardness
Workpieces of different materials have different requirements for grinding wheels, such as steel, non-ferrous metals, and non-metals.
The hardness of the material directly affects the wear rate and grinding efficiency of the grinding wheel. Therefore, it is necessary to select appropriate grinding wheel formulas and types according to the hardness and other characteristics of the material.
Processing Part and Shape
Consider the processing part of the workpiece, such as plane, outer circle, inner circle, curved surface, etc.
The shape of the workpiece determines the adaptability and grinding method of the grinding wheel. For conventional shapes such as inner holes, outer circles, and planes, sintered or plated grinding wheels can be selected. For workpieces with complex shapes, plated grinding wheels are usually preferred because they can better adapt to complex shapes.
Grinding Allowance
The size of the grinding allowance determines the degree of wear and grinding time of the grinding wheel.
Select the appropriate type and grit of the grinding wheel according to the grinding allowance. When the grinding allowance is large, a coarse-grit grinding wheel should be selected to improve grinding efficiency.
Processing Precision and Surface Finish Requirements
Workpieces with high processing precision requirements require high-precision grinding wheels.
Surface finish requirements affect the choice of grinding wheels. Coarse-grit grinding wheels are suitable for workpieces with large grinding allowances, but may not meet high surface finish requirements. In this case, finer-grit grinding wheels need to be used in multiple grinding processes to achieve the required surface finish.
