Position Reference Mark: Diameter 5-50 mm

Component Specifications

Definition

A Position Reference Mark is a calibrated physical feature or indicator on a rotary base that serves as a precise datum point for establishing angular position, alignment verification, and repeatable positioning during machine setup, operation, and maintenance. It ensures consistent reference across rotational cycles.

Working Principle

The mark provides a fixed, known reference point on the rotating element. By aligning sensors, tools, or visual indicators with this mark, the system can determine absolute angular position, synchronize operations, and maintain positional accuracy through mechanical indexing or electronic detection.

Materials

Typically made from durable materials: hardened steel (AISI 4140/4340), stainless steel (304/316), anodized aluminum, or ceramic coatings for wear resistance. Surface often includes laser-etched or engraved markings.
