The company of v-tech s.r.o. is specialized in a design and manufacture of the clamps and clamping systems for CNC machining. All of the devices are designed in its own Design Centre and they are produced precisely on our machinery. We sell the experience that we have acquired in our own production plant. Owing to this, we are capable of implementing solutions so that they meet our requirements to the maximum extent. We make our clamps using the materials of the top quality and the perfect processing can be revealed by a naked eye. We produce all the clamp related components in the Czech Republic.

Quick-Change Clamping System - ZERO POINT

The pneumatic quick-change ZERO POINT clamp is a basic building block of the clamping system portfolio in v-tech. It features the compact dimensions and extraordinary high clamping force used for the clamping pin retraction. This solution is primarily intended for the application on the CNC machining centres where the strictest requirements are imposed for accuracy and safe clamping of a workpiece.

ZERO POINT Advantages

drastic reduction of the setting times needed for a change of the clamping device
high precision of clamping
very high clamping force
body of the heat treated refined steel
self-clamping mechanism - clamping force remains applied even after the pressure air has been disconnected
wide choice of various configurations
positioning slots for indexing by 90°
compact dimensions - pot height is 41 mm only
precise processing
unique structure of the clamping piston which attains the max. clamping force

The ZERO - POINT solution from v-tech s.r.o. will bring you a radical reduction of the time required for clamping and setting of the clamping device on your CNC machining centre. Cut down more than 90% of this time to enhance the productivity of your manufacturing process!

The high pulling force of the pot is possible due to the unique design of the clamping pneumatic piston the shape of which is optimized for even distribution of the contact voltage while the compact dimensions are maintained.

Clamping base 6x

Clamping base with 6 pots

The present centrepiece of our portfolio is the base with 6 clamping pots. The main advantage of the solution is the possibility to position more mechanical vices in several configurations. It can be also frequently used for the needs of series production where a clamp with workpiece is clamped in each pot. With the 90° pot indexing feature, this workpiece can be indexed in a simple manner. Application of the top quality heat treated tool steels and precision processing are the matter of course. Everything is controlled pneumatically.
