Product Introduction
The machine tool bed, column, and saddle are all made of high-quality cast iron from Yunnan. The column features an integral box-type structure, providing excellent thermal symmetry and structural stability.
The machine tool’s X- and Y-axis guards are implemented as integral, insert-type protective shields, ensuring smooth and rapid axis movement. The entire machine is equipped with a double-layer, splash-proof, fully enclosed guard structure, enhancing its aesthetic appeal, maintaining a cleaner working environment, and improving operational safety.
High-precision linear roller guideways are employed, enabling the machine tool to achieve rapid traverse and precise positioning while eliminating stick-slip at low speeds.
The mounting surfaces of linear roller guideways can be finished using precision scraping and lapping, ensuring high, stable, and long-lasting geometric accuracy of the machine tool.
