Common problems and solutions when using a non-heart grinding wheel

Common problems and solutions when using centerless grinding wheels

  1. Causes and solutions for barrel-shaped workpieces:

       The guide plate is tilted to one side of the guide wheel: The guide plate needs to be adjusted

       The surface of the guide wheel is not well trimmed: The trimmer needs to be adjusted to the appropriate angle to trim the guide wheel

  2. Causes and solutions for workpiece surface burns:

       The centerless grinding wheel is too hard: Choose a softer grinding wheel; Increase the speed of the workpiece; Reduce the speed of the grinding wheel

       Insufficient coolant flow: Increase the coolant flow and direct the coolant into the grinding area

       The diamond dresser is not sharp enough: Rotate the dresser angle or replace it

       The cutting speed of the diamond dresser is too slow: Increase the cutting speed of the dresser

  3. Causes and solutions for workpiece surface vibration lines:

       The workpiece is too high from the center line: Adjust the height of the guide plate

       The centerless grinding wheel is unbalanced: Balance and dress the grinding wheel

       The guide angle is too steep: Use the standard 30 ° guide

       The guide plate is too thin or bent: Please use a wide and straight guide plate

       The spindle is worn and the motor vibrates severely: Check the machine parts and replace them effectively

  4. Causes and solutions for workpiece surface scratches:

       The coolant is dirty: Strengthen the filter or replace the coolant

       The centerless grinding wheel is too soft and the grain shedding is too fast: Replace it with harder sand

       The grinding wheel size is too large: Use a finer grit grinding wheel

  5. Causes and solutions for excessive workpiece roundness tolerance:

       The workpiece is set too low: Adjust the workpiece to a position above the center line of the grinding wheel

       The diamond dresser is not sharp enough: Rotate the dresser angle or replace it

       The hardness of the centerless grinding wheel is too soft: Please use a harder grinding wheel

       The guide wheel is loose: Re-tighten the guide wheel screws

       The speed of the guide wheel is too slow: Increase the speed of the guide wheel
