Machining Process (1) Finish the internal face first. (2) Next, finish the internal diameter. (Note) f shall be 0.05mm/rev or less at internal facing.

3. Caution

ø16 Spherical Machining

When machining past the center of the workpiece, R8 insert may break. R7.6 (Corner-R(RE)=0.4mm)

Fix the insert edge at the center of the workpiece. Adjust the machining program to radius minus the value of corner-R(RE). For internal profiling, ap should be the value of Corner-R(RE) and less.

This type of machining is possible, but the chips might scratch the surface.

Poor finish

Corner-R(RE) and less

[Burrs may occur, if ap is Corner-R(RE) and more]
