Biuged BGD 535 Automatic Cross Hatch Tester

The Biuged BGD 535 Automatic Cross Hatch Tester is a motor‑driven, fully automated instrument designed to evaluate coating adhesion using the cross‑cut method. It was developed in accordance with the latest ISO 2409‑2019 and ASTM 3359 standards, which now recommend automatic cross‑hatch testers to ensure uniform cutting speed, consistent load, and repeatable results. The tester determines the adhesion of a coating by cutting a precise grid pattern into the film using a controlled blade under constant load and speed. After one cutting direction is completed, the platform automatically rotates 90°, ensuring perfectly perpendicular cross‑cuts without operator influence. The resulting lattice is then evaluated for coating detachment according to ISO or ASTM classification scales.

Key Features

Standards‑Compliant Automatic Operation

Designed according to ISO 2409‑2019 and ASTM 3359, ensuring uniform, repeatable cross‑cut adhesion testing. The motor‑driven system eliminates variability caused by manual cutting.

7‑Inch Industrial Touch Screen

A full‑color touch interface allows users to set and view all cutting parameters clearly, including speed, load, intervals, and number of cuts.

Programmable Cutting Parameters

Users can set:

• Cutting speed

• Cutting load

• Cutting intervals

• Number of cuts (landscape & portrait)

This ensures precise control for different coating types and thicknesses.

Automatic Load Compensation

The system automatically adjusts load during cutting to maintain a constant force, ensuring consistent cutting depth across the entire test.

Automatic Sample Clamping & Platform Rotation

The instrument clamps the test panel automatically, and after completing one direction, the platform rotates 90° with high accuracy to guarantee perfect cross‑cut alignment.
