になるわけである。In the case shown in Figure 1, the ferrule IC has been roughly polished (in this case, the ferrule IA has been finished polished).
The state is shown below, but next is the ferrule I that has been polished.
After removing A, turn the handle 11 to remove the sliding base 8.
can be moved a predetermined distance to the right in FIG. The ferrule IC is thus placed on the medium polishing area 52 and the ferrule I
B moves onto the final polishing area 53, and as the slider 4 moves back and forth, it comes into contact with each polishing area and is polished by reciprocating.
取付アーム２の一方側が終了したら、セットねじ２１を
