Instruction method for machining
Indicate the tapped hole diameter and the dowel hole (or prepared hole) diameter with the XYcoordinates.
To indicate the coordinates
・The origin is positioned at the upper left corner of the mount face. (However, machining
uses our machining datum as the reference.)
・Indication symbol〈Example of Die Mounted Cam Unit〉

54■ Tapped Hole and Dowel Hole (Prepared Hole, Finish) Machining for Retainer Mounting

Machining standard
・Tapped holes and dowel prepared holes are machined to general tolerances.
・The hole depth is 2.5 times the diameter for both tapped holes and dowel holes. The dowel
pilot hole is processed for 2 times the diameter.
・The dowel hole spacing is machined to the tolerance of a0.02.The hole tolerance is H7.
