Abstract

A FIRST MODE OF THE PRESENT INVENTION RELATES TO A CIRCULAR SUBSTRATE MACHINING METHOD COMPRISING A PROCESS OF, AFTER PICKING UP AND HOLDING A CIRCULAR SUBSTRATE (1) FOR A PRESCRIBED PERIOD OF TIME, GIVING TRIMMING TO AT LEAST AN OUTER EDGE OF THE CIRCULAR SUBSTRATE. A SECOND MODE OF THE PRESENT INVENTION RELATES TO A CIRCULAR SUBSTRATE MACHINING APPARATUS COMPRISING A PICKUP MEANS (3) OF HOLDING THE CIRCULAR SUBSTRATE (1) AND A TRIMMING MEANS (4) INCLUDING A TRIMMING GUIDE (40) WITH WHICH AT LEAST THE OUTER EDGE OF THE CIRCULAR SUBSTRATE HELD BY THE PICKUP MEANS IS ALLOWED TO MAKE ROLLING CONTACT. WITH THE ABOVE CONFIGURATION, THE PRESENT INVENTION IS APPLICABLE TO ELIMINATE ANY POSSIBILITY THAT BURR SCRAPS ETC. FALLING OFF FROM THE SUBSTRATE AFFECT PRODUCTS IN PROCESSES LATER THAN STAMPING.
