What is a Pull-Down Vice?
Like conventional vices, you can use pull-down vices to hold workpieces securely in place during machining. This can be either during machining on a drill press or a CNC portal milling machine.
A precision pull-down vice has two jaws between which the workpiece can be clamped. One of the two jaws is permanently mounted. At the same time, the second one forms the movable unit and is moved with a crank, rod or hexagon key.
If it is foreseeable before the start of machining that high forces will act on the material to be machined, the pull-down vice is the first and best choice as a clamping aid on machine tools.
Two further essential advantages are precision and high clamping strength. Due to the pull-down guide of the mobile clamping jaw, neither the workpiece nor the jaw can tilt during clamping.
Pull-Down Vice prevents the material from lifting off
A challenge in horizontal clamping can be the lifting of the material, which does not allow safe and precise working.
In conclusion, the result of milling or engraving may not be as even and clean as desired. Small and large pull-down vices, on the other hand, with their ground clamping jaws, offer the possibility of giving the workpiece a secure hold.
Guide carriages below the clamping jaws allow smooth and precise movement forwards and downwards so that possible inaccuracies and jamming during fixing belong to the past.
