Bed: The overall box-type slant bed is used to achieve excellent stability and high rigidity. The bed uses finite element analysis (FEM) to optimize the design of the ribs inside the integrated bed. The strength of the bed is 30% higher than the traditional design, and the heat flow balance design can meet the long-term processing requirements. The bed is cast from high-strength cast iron and resin to provide sufficient rigidity, strength and stability for the bed. The guide rails are all rectangular hard rail structure, with large bearing capacity, good anti-vibration performance, improved machine tool characteristics, improved machine tool accuracy and precision stability, and improved machine tool life.
Spindle box: The spindle box incorporates the latest Japanese design technology. It adopts high-precision, high-speed, high-rigidity and independent single-spindle structure to match high-speed and high-torque spindle motors, which greatly improves production efficiency and achieves excellent machining results. The spindle bearing adopts imported bearings (NSK, etc.) and grease lubrication technology, which makes the spindle have high precision, high speed, high load and low temperature rise. It can not only withstand large power and high torque cutting, but also has high spindle precision and life.
