Compact design that can be integrated into mass production jigs!
The jack double screw support (DN support) prevents vibrations during work processing and can be easily locked at the position where it contacts the workpiece. Conventional screw lock-type supports adjust by tightening the lock nut against the tip of the screw that contacts the underside of the workpiece, but tightening the nut causes the support shaft to rise, lifting the workpiece. The DN support utilizes the pitch difference of the double screws to prevent lifting and provide accurate support by tightening the nut.
