Product Description
Advanced Optical Measuring System
Features:
Emphasizing Stability/Precision: The scale's moving component (slide carrier) utilizes five bearings and six springs to ensure exceptional stability and precision for the optical grating measurement system.
Describing Mechanism:For precise optical measurement, the scale's slide carriage incorporates a five-point bearing system supported by six springs.
More Concise: The optical grating scale features a slide carrier stabilized by five bearings and six springs
Explicit Benefit: An optional positive pressure air system can be connected to achieve high dust/water resistance (IP65 rating).
Describing Method & Result: IP65 waterproof protection is achievable by connecting an external positive pressure air purge system.
Action-Oriented: Connect a positive pressure system to enable IP65-rated dust and water protection.
Highlighting Benefit: The scale body features dual T-slots for straightforward installation and simplified alignment adjustment.
Describing Feature & Purpose: A double T-slot design on the scale body facilitates easy mounting and alignment correction. Concise: Double T-slots on the scale body enable quick installation and easy adjustment/correction.
Highlighting Flexibility: Three reference mounting surfaces provide versatile installation options to suit diverse machine tool configurations.
Emphasizing Compatibility: Featuring three mounting reference surfaces for flexible adaptation to a wide range of machine tools.
Benefit Focus: Three reference mounting surfaces ensure adaptable and secure fitting on various machine tool types
Aging Test
Aging tests identify potential flaws in process, design, materials, and other aspects. This enables prompt product design revisions, improving quality and extending lifespan
100% Laser calibration
All glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Accuracy report in QR code
Easson each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
