Self-centering vise with lever mechanism and pneumatic drive, machine table embedded – 2 jaws


Self-centering PSV vises are widely used on working machines to clamp the workpieces.
The thrust for the clamping force on the piece is determinate through the pressure with a double-acting piston incorporated into the vice.
The cylinder, that handle the piston into the vice, can be embed inside the machine table.
The transmission of the thrust, from hub to grippers, happen through two strong levers.


• The parts are joind to assure the movement open/close. They are entirely grilling with millesimal tolerance.
• The final centering adjustments are made after assembly, with vice feeding with working pressure.
• The flat jaw guides have inserted gib for greater precision and finishing of the sliding surface and so as to regain slack resulting from wear.

• Are equipped with effective protection against the infiltration of production waste and with inputs for pressurization.
• Vices are made with predisposition for a forced pressurization and with a strong “Degree of Protection” (IEC 144).
• Feeding connections are located at the cylinder’s bottom and lateraly on the body of the vice.
