Contrast with normal compression screw, the fixed plane of broach is bevel; Using Ball-end thrust screw, the steel ball can adjust its angle and surface-to-surface compress the work piece plane tightly, avoid damage.
Contrast with normal compression screw, the fixed plane of broach is bevel; Using Ball-end thrust screw, the steel ball can adjust its angle and surface-to-surface compress the work piece plane tightly, avoid damage. Using the normal compression screw can only make compression node-to-surface, easy to damage the compression plane.
