Flake graphite cast iron, the lowest tensile strength of which is 200MPa.
High carbon content, high compressive strength and high hardness.
Strong shock absorption and wear resistance. Low thermal sensitivity and
bed gap sensitivity reduce the loss of equipment in using.
It ensures the accuracy of the machine working for a long time,
and it will not deform during its lifetime use.
Casting iron body has high stability .It is unmatched by other materials and structures.
The use of graphite cast iron as a raw material keeps the precision of the machine
tool for a long time and remains unchanged for 50 years. The rough, fine and super-fine
of the imported gantry machining center guarantee the machining accuracy requirements
of the machine body.
