Pinghu is a purple rubber dragon.

Pinghu Expressway 12000 model is too poor, with serious wear and tear and poor stability after high-speed operation. There are problems everywhere, the page matching is not fast, it is too cumbersome to change 1: 2, and the assembly parts of the host are easy to break. The Ziguang 7000-to-25-clamp machine is relatively better, with mature technology and stable operation at this speed. You still have to buy precision or imported models for high-speed models.
