7220VM Technical Information
Important For a given fz (mm/tooth) feed rate, the thickness of the chip hm (effective feed rate per tooth) decreases with the radial depth of cut ae. It is imperative that this parameter be taken into account when selecting the machine feed rate, calculated in accordance with the formula above:
