★5 Key Features
This product serves as a primary accessory for milling and drilling machines, particularly suited for precision component machining.
Parallelism between jaws and perpendicularity of jaws to guide surface ≤0.025MM/100MM.
When the movable jaw moves horizontally, the semi-spherical ball on its surface applies downward pressure, preventing the workpiece from floating upward during clamping.
The flat-jaw vise can be used individually or in multiple units arranged side by side.
The body and fixed jaw form an integrated structure, minimizing backward tilt of the fixed jaw when clamping workpieces.
