Zhongrui is one of China's best press brake manufacturers, having professional information on CNC sheet metal brakes. This article mainly introduces the operation of the E21 CNC system of the press brake bending machine, which is used to guide the user's operation. Everyone can read through this article and master the essentials when purchasing or before using it. 

 

The E21 system provides complete software control, but there is no mechanical safety protection device for the operator or the machine tool. Therefore, when the system fails, the machine tool must be able to provide the operator and the external protection device of the machine tool.

 

1. Product introduction
