There are three main grinding methods for centerless cylindrical grinders; Through type, cut in type, and cut in one through type. Through type centerless grinding. The workpiece is fed along the axis direction of the grinding wheel for grinding. Adjust the small inclination angle of the guide wheel axis to achieve axial feed of the workpiece. There are three main grinding methods for centerless cylindrical grinders; Through type, cut in type, and cut in one through type, through type centerless grinding. The workpiece is fed along the axis direction of the grinding wheel for grinding. Adjust the small inclination angle of the guide wheel axis to achieve axial feed of the workpiece. Suitable for grinding slender cylindrical workpieces. Short shafts and sleeve type workpieces without central holes. Cut in centerless grinding. There is an axial positioning fulcrum on the pallet, and the workpiece is supported at a certain position on the pallet for grinding with a grinding wheel or guide wheel. Used for grinding workpieces with shaft shoulders or platforms, as well as circular, spherical, or other rotating workpieces, centerless grinding, also known as centerless grinding, is a type of grinding process that has two grinding wheels: a guide wheel and a grinding wheel. The guide wheel drives the circular injection shaped workpiece to rotate on the shim, while the grinding wheel plays a role in grinding the workpiece. Centerless Grinding machines belongs to the weekly grinding method. Principle of Centerless Grinding machines Method It consists of a grinding wheel, an adjusting wheel, and a workpiece support! The bracket consists of three mechanisms, among which the grinding wheel actually performs the grinding work, adjusts the wheel to control the rotation of the workpiece, and causes the workpiece to have a feed speed. As for the workpiece support, it supports the workpiece during grinding. There are several ways to cooperate with these three mechanisms, but the principle is the same except for stopping grinding. Centerless Grinding machines Centerless Grinding machines wheel is a type of grinding wheel installed on a centerless grinding machine. It interacts with a guide wheel and a support plate to form a grinding method. The workpiece being processed is supported by the support plate and driven to rotate by the guide wheel in the direction of the support plate. When grinding the workpiece, the surface quality is high and the accuracy is relatively high. In grinding, the selection of grinding wheel particle size is also quite important. Coarse grained centerless grinding wheels are often used for rough grinding processing. Centerless Grinding machines can only process workpieces with relatively low requirements. Generally, in order to accelerate the grinding speed, this method is used for the first processing of workpieces with large processing volume. This is because of its fast processing speed, but the smoothness of the workpiece is low. The quality accuracy of workpieces processed by fine-grained centerless grinding wheels is the opposite, Its processing speed is slightly slower, but the workpiece being processed has a high degree of smoothness. If the particle size is selected, it can achieve a mirror effect. Therefore, the choice of centerless grinding wheel should be based on the specific technical requirements of the workpiece. This also includes the selection of hardness, tissue density, and particle size of the grinding wheel. Grinding different workpieces requires different cutting fluids. For ordinary iron, we only need ordinary cutting fluid, while for grinding aluminum soft parts, kerosene is needed for cold cutting. Centerless Grinding machines method: Fixed type centerless cylindrical grinder with grinding wheel frame. The grinding wheel frame of this type of centerless grinder is fixed on the bed, and the guide wheel and bracket can be adjusted and moved relative to each other. During through grinding or cut in grinding, the guide wheel, bracket, and workpiece perform feed and compensation movements together. The movable centerless cylindrical grinder with grinding wheel frame has the bracket fixed on the bed, and the grinding wheel frame and guide wheel frame can be adjusted relative to the bracket. In special circumstances, feed motion can be performed. The grinding wheel and guide wheel spindle of this type of centerless grinder mostly adopt a double support structure. Tilted centerless cylindrical grinder, the centerline of the grinding wheel guide wheel of this type of centerless grinder is inclined at an angle of α to the horizontal plane. The cutting frame is fixed on the bed, and the grinding wheel and guide wheel spindle are a double support structure. The guide wheel frame can be adjusted relative to the bracket, and the grinding wheel frame can be used for feed adjustment. It can be infinitely adjustable, making it easy to select the ideal dressing speed to achieve outstanding surface quality of the guide wheel; The vertical feed system adopts a combination of manual and synchronous motor feed methods; The horizontal feed component is located inside the bed and is driven by a servo motor to move the ball screw to move the guide wheel seat. It is the primary feed for general production operations and has the characteristics of sensitive movement, high micro feed accuracy, and long service life. The manual feed component is located inside the guide wheel frame. When needed, the spacing between the guide wheel and the pallet can be changed to meet the requirements of processing parts of different diameters, including grinding shadow 1, guide wheel 6, and bed 9. Grinding wheel 1 and guide wheel 6 are respectively installed on bed 9 by grinding wheel frame 2 and guide wheel frame 7, and guide wheel frame linear guide rail 8 is installed under guide wheel 6. Its feature is that a grinding wheel frame guide rail 3 perpendicular to guide wheel frame linear guide rail 8 is set between grinding wheel 1 and bed 9, and grinding wheel frame 2 and guide wheel frame 6 are respectively installed on bed 9. Install guide wheel dresser 4 and grinding wheel dresser 5 on one side of guide wheel frame 7, respectively, Two mutually perpendicular guide rail CNC systems can be used to adjust grinding wheel 1 and guide wheel 6 respectively. After adjustment, the straight guide rail 8 of the guide wheel frame under guide wheel 6 is controlled by the CNC system to adjust the size of the workpiece. Due to the use of two adjusters to adjust the grinding wheel and guide wheel respectively, the guide wheel trimmer is installed on the grinding wheel frame and driven by the movement of the guide wheel frame guide rail, and the grinding wheel trimmer is installed on the guide wheel frame and driven by the movement of the guide wheel frame straight guide rail. The entire system only designs one pair of mutually perpendicular guide rails to complete the movement of the workpiece and the adjustment of the grinding wheel and guide wheel. The large system simplifies the structure and reduces the guide error caused by multiple guide rails.
