Grinding Angle Adjustment Techniques for Dual Grinders

Double-end grinding machines play an important role in mechanical processing. They can effectively reduce positioning errors and processing errors, ensuring high flatness of the workpiece and parallelism of the two planes. Adjusting the grinding angle is a key link in the operation of a double end grinder. Mastering proper adjustment skills can not only improve processing accuracy, but also improve work efficiency.

The double-end grinder is mainly composed of a bed, a workbench, a grinding wheel frame, a grinding wheel dresser, a workpiece clamping device and an angle adjustment mechanism. Among them, the angle adjustment mechanism is the key part to realize the angle adjustment of the workpiece. When making angle adjustments, the basic principles of accuracy, safety and convenience must be followed.

To adjust the grinding angle of the dual grinder, first make sure the machine tool is turned off and check whether all components are intact. According to the processing needs, select the appropriate grinding wheel and workpiece clamping method. When roughly adjusting the angle, adjust the angle adjustment mechanism manually or electrically to bring the workpiece to the approximate required angle, and use angle measuring tools for auxiliary inspection to ensure accuracy of the setting.

Based on the coarse adjustment, make fine adjustments. Use a wheel dresser to finely dress the wheel to ensure optimal contact between the wheel and the workpiece surface. Grinding wheel dressing involves using dressing tools to shape the grinding wheel or remove the dull surface layer to restore grinding performance and correct work surface geometry. This step is crucial to ensure grinding quality and extend the life of the grinding wheel.

After the adjustment is completed, perform a trial grinding operation and check the machining accuracy of the workpiece using measuring tools. If necessary, adjustments can be made until the requirements are met. During the adjustment process, you may encounter problems such as angle deviation or uneven wheel wear. For angle deviations, check whether the locking device of the angle adjustment mechanism is firm and reliable, and tighten it in time. At the same time, angle measuring tools are regularly calibrated to ensure their accuracy. In case of uneven wear of the grinding wheel, the grinding wheel should be trimmed and replaced regularly to maintain the good condition of the grinding wheel, and attention should be paid to adjusting the contact pressure between the grinding wheel and the workpiece surface to avoid uneven wear caused by being too big or too small.

In addition, some dual grinders are equipped with innovative grinding head angle adjustment mechanisms, such as products from Yuhuan CNC Machine Tool Co., Ltd., which provide precise head angle adjustment grinding by adjusting the screw and a universal spherical adjustment. structure, reducing the difficulty of adjustment, improving work efficiency.

In summary, adjusting the grinding angle of a double grinder is a technical activity that requires the operator to have strong professional knowledge and rich practical experience. By following the principles of precision, safety and convenience and mastering the appropriate adjustment steps and techniques, you can ensure high-quality processing of parts and improve overall work efficiency.
