Zero-Point Clamping System Provides a Fixed, Precise,
Rigid Solution That Can Also Be Changed in Seconds
The CapteX zero-point clamping system
from Hainbuch GmbH Spannende
Technik is impervious to both
the centrifugal forces involved in turning
and the extreme static transverse
Developed in Japan and marketed by
an associate of Kemet International
Ltd., primarily as an added feature of
its own specialist grinding and lapping
machines, the Eco filtration system is
available to anyone wishing to have
coolant and cutting oils cleaned down
to the 0.01-μm level.
An additional benefit of the Eco system
is the lack of filter cartridges and
paper bands. The system also is capable
of filtering every type of material
from the fluid, including wood, plastic,
and nonmetallic materials, as well
as the more familiar steels and grinding
wheel compounds. Better workpiece
surface finishes and a lower level
of machine maintenance result from
implementation of the patented filtration
system.

forces normally associated with milling.
Thanks to an ingenious ring mechanism
with sliding wedges, this
machine interface can be fixed in
place with a very high degree of stability.
Its resistance to deflection is practically
indistinguishable from a conventional
clamping setup that employs
multiple screw joints.
However, not only does the CapteX
provide rigid and
stable clamping; it
can be changed
quickly, too. The
user can loosen
and clamp the
entire interface
—including the
clamping device’s
draw mechanism—with
a single
screw, which is
easily accessible.
Like most of Hainbuch’s
clamping devices,
CapteX utilizes the
pioneering Centrex tech-
nology; precision steel balls vulcanized
into a rubber ring ensure that the system
positions with better than 0.003mm
repeatability. Extremely insensitive
to contamination, since only the
steel balls have point contact, CapteX
can be joined and separated easily. The
system is equipped with a positive-fit
bayonet so that it can also be used
safely on a rotating spindle.
Hainbuch’s zero-point clamping
system is configured for use on all conceivable
machines. The interface enables
all the machines in a production
facility to be standardized in one
stroke, and allows all the clamping
devices in the facility to be swapped
from machine to machine in seconds.
Currently, CapteX is available for
stationary use on dividing attachments,
turntables, and slow-rotating
spindles (those running no faster than
1,800 rpm). A version for fast-rotating
spindles is in development.

Patented Filtration System for Grinding and Lapping Machine
Coolant and Cutting Oils Can Be Built into a Machine Cycle
Two filters, each
containing a coil
around a second
coil that, at the correct
flow rate, generates
static, attract
and hold small particles.
When they
are saturated, a simple
sliding mechanism
and change of
flow direction move the sludge into a
container; then the filters move back
into operation. This entire process
takes no more than 20 seconds. Filter
discharge can be either accomplished
manually or built into a machine cycle
as an automatic process.
The Eco filtration system has been

and is moving into the medical technology
field. Users are finding that
grinding wheels require less in-cycle
dressing and that components are not
susceptible to particle-caused damage.
Two-month free trials are available.
