Application Case with No Existing Hole Finishing ap=0.5mm ap=0.5mm Boring (Corner-R(rε)=0.4mm) (Corner-R(rε)=0.4mm) Spherical Machining Spherical Internal Machining Facing (Note) f shall be under 0.05mm/rev at internal facing. Case with Drilled Hole Internal Facing Spherical Machining (1) (2) Internal Drilled Hole Facing Machining Process  (1) Finish the internal face first. (Note) f shall be under 0.05mm/rev at internal facing.  (2) Next, finish the internal diameter. 3. Caution φ16 Spherical Machining When machining past R8 the center of the workpiece, R7.6 insert may break. (Corner-R(rε)=0.4mm) Fix the insert edge at the center of the workpiece. Adjust the machining program to radius minus the value of Corner-R(rε). For internal profiling, ap should be less than the value of Corner-R(rε). ap This type of machining is possible, but the Less than Corner-R(rε) chips might scratch the surface. [Burrs may occur, if ap is bigger than Corner-R(rε)] Poor finish F53
