  • Dry cutting (or air blow) at a depth of cut up ae to 0.3 mm (allowable max. Z-feed milling
0.5 mm) and a pick feed pf from 0.5pTraverse feed milling
to 1.0 mm is recommended.fa

TZF11 type cutters are not designed e J

to adjust dynamic balance. Therefore, when the tool’s overhang ratio (cutter diameter-to-length) exceeds 6:1, special care should be taken with

the revolution speed. (At first, start

the machining at 50 % of the speed K

shown in the table of the standard

cutting conditions, and then gradually

increase the speed whilst confi rming

safety.)

  • To produce highly accurate surface finish, use the cutter on a machine with suffi cient rigidity. L
