Casting components on the Tongtai's GT series are made of high quality cast iron which confer the machine a high grade of stability.
The Y-axis is driven by a single ball screw at the center of gravity to ensure the parallelism of slide moving. The gravity center of Y-axis moving components falls within the supporting range of sliding block, it decreases the decline of spindle and improves dynamic stability. Less overhung spindle provides excellent rigidity in heavy duty machining. All these characteristics made the GT-800E an incredible five axes machine for your most difficult pieces.
