can be used alone, or multiple units can be used together
angle solid semi-spherical ball can be generated under the lock of the force to eliminate the tiger's mouth floating and workpiece tilt
strong and powerful material ~ vise body using high tensile tensile graphite cast iron (FCD60 ~ 60kgs / mm). (80,000psi) strong tensile strength, high wear resistance, easy to deformation
vise sliding surface are hardening heat treatment HRC45 degrees or more, and by precision grinding, can maintain long wear resistance and accuracy.
