    CSL-B Impact Specimen Notch Electro-Hydraulic Broaching Machine

    The CSL-B Impact Specimen Notch Electro-Hydraulic Broaching Machine is a specialized equipment designed for processing V-shaped and U-shaped notches on impact test specimens. It ensures reliable and consistent machining quality through a one-pass broaching process. Utilizing hydraulic transmission and electric control (solenoid valve-driven broach movement), the machine enables adjustable cutting speeds and automatic lubrication for blade cooling. The processed specimens fully comply with GB/T 229-2020​ (Charpy Pendulum Impact Test Method for Metallic Materials). With structural modifications and key component replacements, the machine can also meet international standards such as ASTM E23-02a, EN 10045, and ISO 148.
