Grinding machining is a method where the workpiece is processed using a grinding wheel rotating at high speed. The grinding wheel is composed of three elements (abrasive grains, bonding material, and pores), with the abrasive grains acting like cutting blades to machine hard materials that are difficult or impossible to process by other methods, and also to enhance surface finish.
This method is commonly applied for machining high-precision parts, used in stamping dies, forming, and critical parts of mechanical components. The machines used in grinding operations include surface grinders, cylindrical grinders, NC surface grinders, and NC cylindrical grinders. Additionally, there are centerless grinders for mass production of cylindrical pins, profile grinders for machining complex shapes, and jig grinders for high-precision hole machining.
