Which of the following statement is wrong as regard to down milling?

The surface milled appears to be slightly wavy.

The chips are disposed off easily and do not interfere with the cutting.

It can not be used on old machines due to backlash between the feed screw of the table and the nut.

The coolant can be poured directly at the cutting zone where the cutting force is maximum.
