Reference Edge: Width 20-100 mm, Length 100-3000 mm

Component Specifications

Definition

A Reference Edge is a critical component in industrial moving platforms, typically a hardened and ground straight edge or rail that serves as a primary datum for positioning, guiding, or aligning moving elements. It ensures repeatable linear motion with minimal deviation, often integrated with sensors or measurement systems to provide feedback for closed-loop control in automated machinery.

Working Principle

The Reference Edge operates by providing a highly accurate, stable linear surface against which moving parts align or slide. It establishes a geometric reference plane, enabling precise control of motion along one or more axes through mechanical contact or non-contact sensing (e.g., optical or inductive sensors detecting the edge's position).

Materials

Typically made from hardened tool steel (e.g., AISI 52100, D2), stainless steel (e.g., 440C), or carbide-coated alloys for wear resistance. Surface hardness ranges from 58-65 HRC, with roughness (Ra) of 0.4 μm or better.

Frequently Asked Questions

What is the primary function of a Reference Edge in a moving platform?

It provides a precise linear reference for positioning and guiding moving parts, ensuring accurate and repeatable motion alignment in automated systems.

How is a Reference Edge different from a standard guide rail?

A Reference Edge is specifically machined to higher tolerances (e.g., straightness, flatness) and often serves as a master datum for measurement or calibration, whereas guide rails primarily provide structural support and motion guidance.
