HC series The base, column, slide, and headstock of this machine tool are made of high-quality cast iron HT300. The design of dense bars in the large foundation section is adopted, and finite element analysis is adopted to ensure high bending and torsional rigidity, so that it has a high natural frequency and improved vibration resistance. The triaxial hard rail (quenching) meets the technical performance requirements. Large amount of knife and high precision requirements. After secondary aging treatment, internal stress is eliminated. It has the characteristics of good overall rigidity, good vibration absorption and seismic performance. It is widely used in the processing of box parts, shell parts, and disc-shaped parts in the military, automobile, mold, and machinery manufacturing industries. After a single clamping, the parts can be processed in multiple processes such as milling, boring, drilling, expanding, reaming, tapping, etc., with high precision, high automation, high reliability, high degree of mechanical and electrical integration, simple operation, beautiful overall appearance .
