Cutting off, Grooving, Forming
Rotary sawing is not limited to cutting off.



It can also be used for grooving and forming applications with the same technical advantages. When grooving and forming with a circular saw, the profile of the saw must match the profile of the resultant part.

As an example, deep grooving is a great application for using a saw rather than a single point tool. Due to the low chip load, grooves stay square to the part and thin walls between multiple grooves do not deflect. Coolant delivery is improved when sawing deep grooves because the chips are immediately ejected allowing coolant to easily flow into the grooves.

Grooving and cutting off can often be done at the same time by mounting multiple saws onto the same arbor. The saws must be spaced appropriately by using spacers ground to the needed thickness. Usually, the set up is such that the first part is being cutoff while the next part is being grooved. If a part has multiple grooves, additional saws can often be mounted onto the same arbor.
