The CK8450 CNC roller grinding machine bed features a whole 4+1 guideway structure, with four rectangular guideways horizontally arranged on the bed to provide movement and positioning for the saddle and tailstock, and an auxiliary guideway set on the vertical front surface of the bed for additional support of the saddle. This design ensures better rigidity for the saddle and tool holder, enabling them to bear greater cutting torque.

The bed base guide rail is treated with overall ultra-audio quenching, complemented by imported guide rail soft strips, ensuring minimal wear on feeding components for long-term high precision and stability. The design features a certain height difference between the saddle guide rail and the tailstock guide rail to prevent chips and coolant from entering the saddle guide rail.
