Self-centering vise with wedge-hook mechanism and pneumatic or hydraulic drive – jaws


Self-centering MAE vices are widely used on working machine to clamp the workpiece. These vices have an expecially relation between price and quality.
The thrust to obtain the clamping force on the piece is determinate through the pressure with a double-acting incorporated into the vice. The cylinder, that handle the pistons into the vice, can be embed inside the machine table.
The transmission of the thrust, from hub to grippers, happen through inclinated plane to assure maximal rigidity and precision.
The realisation of the joinds between the particular (drive hub-jaw) are characteristic of Tecnomors‘ vices. The construction of the inclined plane seat inpit 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 joined to assure moviments open/close with grinding of centesimal tolerance. The final centering adjustments are made after assembly, with vice feeding with working pressure through special equipment. 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 greater precision and finishing of the sliding surfaces and so as to regain slack resulting from wear.
MAE are equipped with effective protection against the infiltration of production waste and with inputs for pressurization.
Vices are made with predisposition for a forced pressurisation and with a strong “Degree of Protection” (IEC 144).
Feeding connections are located at the cylinder’s bottom and laterely the body of the vice.
