Toprem tetter Pinion Whole Depth of Outer Cone Distance finish and better cutter life are obtained when climb-cutting provided the gears or pinions are rigidly supported during the cutting operation. r7 F Up to 0.275" This is true for both roughing and finishing. This I E 0.276" to 0.375" machine can be set-up to cut on either the up-roll C 0.376" to 0.500" or the down-roll but normally the cutting is done B 0.501" to 0.650" on the up-roll. Therefore, right-hand cutters will be A 0.651' to 0.800" most commonly used when generating roll is Z 0.801" ond Up employed.
