As the mold is moving in the direction of large-scale, tens of tons to tens of tons of mold is very common, so the machine tool table can withstand large weight, which requires the equipment must have a large load and high rigidity characteristics, but also must be large enough Table size and work trip to adapt. The other mold material strength and hardness are high, coupled with the use of large elongation is often a small diameter end mill processing mold cavity, so the process prone to flutter. In order to ensure the accuracy of parts and surface quality, mold manufacturing high-speed machine tools must have a high dynamic and static stiffness, in order to improve the positioning accuracy of the machine, tracking accuracy and anti-vibration ability.
