The example illustrated in the figure refers to a connecting rod with the following holes drilled into it: one ∅ 25 H7 hole and two ∅ 10 H7 holes.
Also in this case, a 8.02 keyway was executed directly on the machining centre.
This operation avoids having to move the workpiece, executing keyway broaching timed exactly with the two ∅ 10 H7 holes.
Also, machining time is considerably shorter.
