Graduation marks: Temperature range -20°C to +80°C

Component Specifications

Definition

Graduation marks are precisely engraved or printed markings on scale components that provide reference points for measurement, calibration, and alignment. These marks are essential for ensuring measurement accuracy, repeatability, and traceability in industrial processes. They typically consist of lines, numbers, or symbols arranged at regular intervals according to standardized measurement systems.

Working Principle

Graduation marks function by providing visual reference points that correspond to specific measurement values. When aligned with a pointer, indicator, or measurement device, they enable users to determine precise positions, dimensions, or quantities. The marks are designed based on geometric principles to ensure linear or angular accuracy, with spacing calculated according to the required measurement resolution and scale range.

Materials

Stainless steel (AISI 304/316), aluminum alloys (6061-T6), hardened tool steel, ceramic coatings, or engineered polymers with high wear resistance and dimensional stability. Surface treatments include anodizing, etching, laser engraving, or precision printing with durable inks.

Frequently Asked Questions

What is the difference between graduation marks and regular scale markings?

Graduation marks are precision-engineered with strict dimensional tolerances and standardized spacing for industrial applications, while regular scale markings may have looser tolerances for general-purpose use.

How are graduation marks applied to scale components?

They are typically applied through precision methods like laser engraving, chemical etching, diamond scribing, or photolithography to ensure accuracy and durability.

What factors affect the longevity of graduation marks?

Material selection, surface treatment, environmental conditions (humidity, chemicals), mechanical wear, and proper maintenance all impact mark durability and readability.
