The angle-fixed semi-spherical clamping mechanism generates downward locking force to prevent workpiece floating and misalignment.

The vise body employs robust and durable spherical graphite cast iron FCD-60 with high tensile strength, resistant to deformation.

All sliding surfaces undergo high-frequency induction hardening heat treatment to enhance wear resistance and precision.

Workpiece clamping maintains a tolerance within 0.01mm of the vise center position.
