MANUFACTURE OF OPTICAL CIRCUIT COMPONENT AND OPTICAL FIBER COMPONENT

摘要

PROBLEM TO BE SOLVED: To process obliquely a connection end surface of an optical circuit component or an optical fiber component by sharply reducing a grinding process or without the grinding process. SOLUTION: By using a cutter 10 supporting a spindle 11 fitting a rotary grindstone 13 to a main shaft 12 so that the main shaft 12a of the spindle 11 is arranged obliquely for the direction 14a parallel to a horizontal surface of a work hold table 14 for the work hold table 14, a PLC substrate 20 held on the work hold table 14 so that the longitudinal direction of its waveguide becomes parallel to the horizontal surface of the work hold table 14 is cut off.
