Two jaws oil-hydraulic self-centering vice

Oil-hydraulic self centering OSV vices are widely used on working machines to clamp the work piece.

The thrust for 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 inclined planes.

The realisation of the joinds between the particulars (drive hub – jaw) are characteristic of Tecnomors vices. The construction of the inclined plane seat in pit up the jaw allowed the height length guide.

The drive hub has an extra guide in the gib to assure an added precision and affidability.

The parts are joind to assure the movement open/close. They are entirely grilling with millesimal tolerance. Entirely constructed in UNI 18 NiCrMo5 hardened steel.
The final centering adjustments are made after assembly, with vice feeding with working pressure through special equipment (see “Reference Diagram” into “Technical Date”).



All the pieces are made with extreme precision to assure centesimal allowances in construction.
On all our vices the flat jaw guides have inserted gib for graeter precision and finishing of the sliding surfaces and so as to regain slack resulting from wear.

The vices OSV of tecnomors are equipped with effective protection against the infiltration of production waste and with inputs for pressurization (see “Protection against the infiltration of production in “Technical Date”).

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 laterely on the body of the vice.
On request tecnomors can supply as optional a supplementary oil-hydraulic connection.
