Tool locating ring CP780 series

Overview
These Flex locator receivers are designed for use with CP157 tapered locator pins. They mount on base plates and fixture plates to provide accurate locating and repeatable positioning with a repeatability of 0.005 mm (5 µm). The Round type has a full tapered surface for full-surface reference; the Diamond type has two opposite tapered surfaces for rotational/directional positioning; the Spacer is used where locating is not required. Body material: 4140 steel, black oxide finish, quenched and tempered, precision ground.
