It can not be used on old machines due to backlash between the feed screw of the table and the nut.
The chips are disposed off easily and do not interfere with the cutting.
The surface milled appears to be slightly wavy.
The coolant can be poured directly at the cutting zone where the cutting force is maximum.
The work is reciprocated as the wheel feeds to produce cylinders longer than the width of wheel face
The work rotates in a fixed position as the wheel feeds to produce cylinders equal to or shorter than the width of wheel face

Rake angle
Cutting angle
Clearance angle
Lip angle
The larger side rake angle produces chipping.
The smaller rake angle produces excessive wear and deformation in tool.
The side cutting edge angle (less than 15°) increases tool life.
The increase in nose radius decreases tool life.
