Function summary:

       The automatic laser marking machine is an auxiliary tool for marking the distance before the test of steel bar tensile test。The marking distance before the test can be more convenient to determine the elongation of the test specimen after breaking, so as to achieve the purpose of tensile test more accurately。Meet GB/T 228.1-2010 "Metal materials tensile test Part I: Room temperature test method" requirements。

特点：

• A high-power laser transmitter combined with a polarizing lens is used to move the laser marking position.

• The sample is sent to the marking range of the laser head in the form of the sample plate moving;

• The sample tray can place 12 samples at a time, which basically meets the needs of a test;

• In the form of data import, a computer-controlled polarizing lens can be used to leave more text information on the specimen surface。
