The three axles provided with ultra-high rigid roller rails can bear equal loads in four directions. The roller retainer provided may prevent deviation and realize balanced and stable movement, ensuring the accuracy and stability of the machine tool after long-term operation.
The contrast test of damping automatic vibration response has proven that mineral castings have strong vibration absorption, which is 10 times that of cast iron. Under large dynamic load, the stability of machine tool accuracy is ensured, and the machining quality of workpiece surface is improved by 20%.
The thermal conductivity is 1/20 of that of cast iron, and the specific heat capacity is 2.1 times of that of cast iron. In the process of parts machining by the machine tool, the thermal influence is the main factor causing the machining dimension deviation. Excellent thermal stability and thermal inertia may effectively control the deformation of the machine tool caused by temperature changes and ensure the stable machining accuracy of the machine tool.
The moving parts are welded by high-strength low-alloy steel. The elastic modulus of moving parts is about 1.4 times that of cast iron, and the overall rigidity of the structure is improved by more than 30%.
On the premise of the same rigidity, the weight of steel weldments is reduced by about 20%~30% compared with iron castings, which effectively reduces the inertia of moving parts and improves the dynamic response by 10%~20%.
Compared with the cast iron material with the same structure, the natural frequency of steel weldments is significantly improved, the possibility of resonance during cutting is reduced, and the cutting stability and machining accuracy are improved.
