The CST-50 impact specimen notch projector is a specialized optical instrument designed and developed by us based on the actual needs of domestic users and the requirements of GB/T229-94 "Metallic Charpy notch impact test method" for impact specimen notches. It is used to inspect the machining quality of Charpy V-notch and U-shaped impact specimen notches. The instrument uses optical projection method to enlarge and project the contour of the tested impact specimen V or U-shaped notch onto the projection screen, and compares it with the standard template of the impact specimen V and U-shaped notch on the projection screen to determine whether the notch machining of the tested impact specimen is qualified. Its advantages are easy operation, intuitive inspection comparison, and high efficiency.
