The semi-automatic tensile specimen edge grinding machine strictly follows the requirements of GB/T228.1-2010 "Metallic Materials Tensile Testing Room Temperature Test Method", and is a device that removes work hardening caused by shearing or stamping of tensile specimens. The equipment is set according to the LC length of the tensile specimen, with a grinding length and transition arc radius that perfectly matches the shape of the specimen to be ground, and is better used in conjunction with a punch press.

2、 Product Features：

1. The hardened area generated during the punching process of the tensile specimen of the ground plate;

2. The grinding platform matches the shape of the sample to ensure that the tolerance of the parallel and circular arc parts of the sample meets the standard;

3. Accurately adjustable feed, with a feed accuracy of 0.05mm;

4. The shape tolerance of the sample after grinding shall not exceed 0.06mm;

5. The roughness Ra of the sample grinding surface is ≤ 0.8.
