By configuring the ratio to be 5/1, escape of chips can be significantly improved. In this case, if the surface area ratio is less than 171, the effect will not be sufficient, and if it exceeds 5/1, the surface area of the abrasive neck (11) will become too small, which may result in poor cutting quality.
