COSTS REDUCTION

With the new Zeropoint Quickclamping systems we offer you significant reduction of machining and
investment costs.

In a workstation if you have to change the fixtures 4 times per day like in the chart above with an average
period of 30 minutes for executing this duty, the investment cost of 3580 € will be amortized after a period
of around 22 workdays.

CUSTOMER BENEFITS

This clamping and positioning system is permanently in a clamping situation and opens/releases only
when external pressure is introduced.This method avoids parts and fixtures from moving when there is no
external pressure.

– Reduce The Time Of Fixture Change
– Reduce The Manufacturing Process Time
– Minimize The Manufacturing Costs
– Increase The Precision
– Assure A Precision Of Repeatability Up To 2 Microns
– Increase The Quality Of The Workpieces
– Facilitate The Use Of Production Machines
– Make Easier The Machining Of 6 Sides
– Facilitate The Positioning
– Increase The Lifetime Of The Production Machines
– Secure The Production Machines And Manufacturing Processes

Horizontal Zeropoint Quickclamping cylinder

With our new Zeropoint Quickclamping
cylinder with piston-catching, we make the palletizing…
easier and quicker
No search of holes
No damage of zero point
hole and nipples
No risk of injury

ADVANTAGES:

– With and without blow out.
– Completely in Stainless steel.
– Applicable in all positions without fit-up aids.
– W hen the mechanism is out of service, the pis-

ton-catching stay out, it can be locked, thus the
discs spring are not forced.

Can be integrated in:

– Clamping towers
– Clamping angles
– Automatized handling devices
– General mechanical

Left figure:
During a handling duty with
the crane, handling devices
or robots, we can offer you
thanks to the horizontal ni-
pple the greatest possible
protection and comfort.

Right figure:
Just after the pallet are
hung up by the horizontal
nipples, then it can be easy
to release or taking out
with hand. On request we
can automatize the transla-
tion movement.
