Weight reductions and enhancement of rigidity
are achieved by the design decreasing stressconcentrations based on CAE and durability test by
our servo press machine. Consequently,
rapid stamping can be expected.

Instruction method for machining
Indicate the tapped hole diameter and the dowel hole (or prepared hole) diameter with the XY
coordinates.
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―M…Tapped hole, ―N…Dowel prepared hole, ―K…Dowel finish hole

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.

■ Panel Machining Position Reproducibility for V Guide (Bottom Guide) TypeThe clearance between the Cam Holder and the Cam Slider absorbs the error in the Cam Holder
and Cam Driver installation machining. The Cam Slider main unit operates with its position
secured by the Driver and Cam Slider V guide structure. Therefore, the Piercing punch (Retainer)
position can always be replicated.
