MAV Self-centering vice with mechanic working
FEATURES:
Mechanical self-centering “MAV” vices are widely used on working machine to clamp the work pieces.
The thrust to obtein the clamping force on the piece is determinate through a torque on the lead screw.
They are suitable to be apply with milling machine or tool machine with a pneumatic or oil-hydraulic feeding’s availability.
The characteristic, that make easy to apply these vices are:
- high sliding run of grippers;
- self-centering sistem.
The thrust is dirctly from lead screw to gripper.
The load screw is made with an acme thread to blocking work pieces also in open side.
Screw is supported by a bearing into an a central “box”.
The final centering adjustments are made after assembly, with vice feeding with a torque on the lead screw (see “Reference diagram” into “Technical Date”) using special equipments.
All the pieces are made with extreme precision to assure centesimal allwance in construction.
On all our vices the flat jaw guides have inserted gib for the sliding surfaces and so as to regain slack resulting from wear.
The vices “MAV” of tecnomors are equipped with effective protection against the infiltration of production waste and with a inputs for pressurization (see “Protection against infiltration of production).
In the serial construction the predisposition for pressurization is not included, because the mechanic closing sistem has usually a pneumatic feeding.
