Only by changing the electrodediameter, spherical_top wheel of different diameters can be dressed.
只要改变工具电极直径，即可对不同直径的球头砂轮进行修整。

The contact electric resistance of the power supply electrode is in direct proportion to earth electric resistance rate, and in relation to the diameter of the electrode and the depth of the earth.
供电电极的接触电阻与大地的电阻率成正比，与电极的粗细及入土深度有关。
