In the field of mechanics, "flat circular cutter runout value" usually refers to the radial or axial runout amplitude generated by the flat circular cutter when it rotates, which is an important indicator for measuring tool accuracy.
• Meaning:
When the tool rotates, the maximum deviation of the blade or the cutter body from the ideal rotation axis, generally expressed in microns (μm). For example, radial runout refers to the swing of the blade along the radial direction when it rotates, and axial runout refers to the movement along the axis direction.
• Impact:
◦ Too large a runout value will lead to reduced cutting accuracy (such as uneven cuts, dimensional deviations), increased tool wear, and even equipment vibration or noise.
◦ For precision machining (such as cutting processes in printing, packaging, textiles and other industries), the runout value must be strictly controlled (usually required to be within a few microns to tens of microns).
• Inspection and adjustment:
It can be detected by tools such as dial indicators or laser vibrometers. If the runout value is out of tolerance, it is necessary to check whether the tool is installed in place, whether the tool handle or spindle is worn, and re-clamp or replace the tool if necessary.
