XYZ positioning (dual surface positioning)● Tapered surface of locate ring is expanded and deformed in radial direction by the locate base to firmly position
X axis and Y axis.
Pallet is attached to seating surface of base plate and positions Z axis. The positioning of X, Y and Z axes by tapered
surface and seating surface completes the XYZ positioning (dual surface positioning).

ManualRealizing high-accuracy positioning● In the case of ordinary positioning pin, it is common knowledge that the clearance is provided between the pin
and the hole to allow the dimensional tolerance between the two pins, and to facilitate the positioning operation, however there is a risk of impairing the positioning repeatability depending on the volume of clearance sothat the positioning re-adjustment must be done when re-setting the objects.
Pal fix can exert 3μm of repeatability and requires no re-adjustment after setting the objects.
