Workpiece surface Internal Grinding is generally clamped on the table, or by electromagnetic suction fixed in the electromagnetic work bench , and then use the wheel perimeter or face grinding workpiece surface grinder ; centerless grinding usually centerless cylindrical grinding , that do not work top or the centering chuck and support , while the outer surface of the workpiece to be ground for locating surface of the workpiece is located between the grinding wheel and guide wheel , supported by the pallet , this grinding machines, high efficiency, easy to automate , multi-purpose in mass production . Tool grinder is designed for tool manufacturing and tool sharpening grinder, a universal tool grinder , drill grinding machines , pull the blade grinders, tool grinders and other curves , multi- tool factory and machinery factory for the tool shop . Abrasive belt grinding machine is fast moving belt as abrasive, workpiece supported by the conveyor belt , efficiency several times higher than other grinders , power consumption is only a fraction of other grinders , mainly used for processing large-size panels , heat difficult materials and mass production of flat parts. Specialized grinder is specifically a certain type of grinding parts such as crankshafts, camshafts, splined shafts , rails, blades, bearings and gears and threaded raceway other grinder. In addition to these categories , there are honing machines, grinding machines, jig grinders and grinding machines and other types of billets .
1Internal Grinding Mainly in the cylindrical grinder for grinding outer cylindrical shaft workpiece end face of the outer cone and shaft shoulder . When grinding , the workpiece speed rotation , if the workpiece while longitudinally reciprocating longitudinal movement in every single post- stroke or two- stroke relative to the workpiece for grinding wheel infeed , called vertical grinding method. If the length is greater than the width of the grinding wheel surface , the workpiece during grinding without longitudinal movement , but the wheel relative to the workpiece continuous infeed called plunge grinding method. General plunge grinding method is more efficient than vertical grinding method. If Dresser into forming surface , cut into the outer surface of the grinding method can be processed forming. Grinding 2 . Internal grinding Mainly used for the inner grinder, universal cylindrical grinder and jig grinder grinding the workpiece on a cylindrical bore , tapered bore holes and the end face . Generally use the vertical grinding method. When forming the inner surface grinding , can be cut into the grinding method. When the jig grinder grinding bore, workpiece fixed on the table , except for the high-speed rotating grinding wheel , but also around the centerline of the grinding holes for planetary motion . When internal grinding , due to the small diameter grinding wheel , grinding speed is often less than 30 m / sec. 3 . Surface grinding Mainly used for grinding flat , groove on the surface grinder , etc. . Surface grinding in two ways: with the outer surface of the grinding wheel called peripheral grinding , the general use of horizontal shaft surface grinder , as it can be processed by forming various shaped grinding wheel surface ; using face grinding wheel is called the end mill cut , the general use of vertical shaft surface grinder .
