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.
Technical Parameters
  • Width 20-100 mm
  • Length 100-3000 mm
  • Flatness ≤ 0.005 mm
  • Thickness 10-50 mm
  • Surface Hardness 58-65 HRC
  • Straightness Tolerance ≤ 0.01 mm/m
Standards
ISO 1101, DIN 876

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
