Longkou pentahedron machining center

As is known to all, the parallelism, horizontality, and coaxiality between the two shafts and four ends of a double-horizontal shaft forced mixer are directly related to whether the seal of the mixer is tight. In 2002, Zhengzhou Changli interest rate first used mixer-specific combined machine tools in the industry to ensure concentric accuracy. In 2005, an imported gantry-type pentahedron machining center was added to the original foundation, and the accuracy level of the concentricity of the mixer was raised to a new level in the industry, which effectively guaranteed the quality of Changli mixer.
