Drill ① Holes for the positioning pins
through the mounting surface of the
machine.
Mount the ② Rotating shaft so that
it protrudes out from the mounting
surface as shown in the diagram.
・ Provide one of the two positioning pin
holes with a slot shape (long hole) as
shown in the figure. If machining a slot
shape is difficult, drill out a Φ6 (0.236)
or larger round hole.
・ Be sure to maintain the amount
of protrusion of the rotating shaft
mounted to the unit output shaft at
34 mm (1.339 in.) or more.
