(Note1) Matching-hole machining: Dowel hole machining without using NC is performed by installing the retainer with punch mounted onto the upper die, aligning the punch and die edges, then using a drill to create a hole while the retainer is attached. A reamer is then used to simultaneously machine the retainer and upper die.
(Note 2) Correct use of end retainers and square retainers
With a square retainer, the punch is inserted at the center of the shape. As a result, this type provides superior balance. However there are many cases in which the holes that will actually be machined in the product are close together and a square retainer cannot be used due to space problems. End retainers are used in such cases when there is insufficient mounting space.
