Flake graphite cast iron with a minimum tensile strength of 200 MPa. High carbon content, compressive strength and hardness. High shock absorption and wear resistance. Good casting performance and cutting performance. Keep the accuracy of the machine tool for a long time, unchanged for 50 years.
1.Easy processing and low cost (the most cost-effective machine bed is cast iron)
2.Not easy to deform (high strength cast iron material strength and stiffness, small plastic deformation, and not easy to deform)
3.Ball milled cast iron with high wear resistance
4.Easy to scrape, easy to form oil film
5.Shock absorption (the high speed after the machine is turned on is very easy to generate vibration, and the heavy cast iron material and its high content of graphite can play the role of shock absorption)
