ASM 90 Quick Change Clamping Chuck
Now Offered with Unilock Workholding System |
| |
| ELK
GROVE VILLAGE, IL - A new ASM 90 Quick Change Clamping Chuck that
combines all of the popular features of the Unilock clamping
system in a new compact design is now available from BIG Kaiser
Precision Tooling Inc. While only 90 mm in diameter, the ASM 90
accepts the same clamping knob as chucks twice its size. It is the
ideal solution for smaller machines with limited travel range. |
| |
| Compatibility
and rigidity are achieved by utilizing the same clamping knob and
ram system as larger Unilock chucks. The system standard Unilock
40 mm clamping knob can be attached directly to work pieces or fixtures
with up to a 12 mm thread. The easily mounted clamping knob provides
affordable accuracy and rigidity. |
|
|
| "The
availability of the large retention thread relative to the chuck's
small size is useful for high torque applications. The chuck is
extremely well suited for quick and accurate changeover in limited
space environments. The ASM 90 is also well suited in a setup where
each chuck positions or stabilizes a portion of a large part,"
says Gerard Vacio, BIG Kaiser's Product Manager, Workholding Systems.
In multiple chuck applications, the spacing and total number of
chucks determines the rigidity of the quick change clamping system. |
|
| The
spring-based mechanical clamping system of the ASM 90 supports an
air boost system to increase clamping force by up to 30% over spring
retention alone. This increased clamping force remains even after
the air source is disconnected. |
|
| A
low-cost workholding system that eliminates costly fixturing setup
time, the Unilock combines a chuck with a pallet that holds
the workpiece. Unilock chucks deliver .0002" repeatable
positioning accuracy. Retention forces with M10 retention threads
start at 7,868 ft lbs. per chuck. |
|
| The
Unilock workholding system provides a solution for two of the
manufacturing industry's toughest setup problems: repeatability
of location from one workpiece blank to another and transfer of
work from one machine tool to another. It enhances accuracy and
provides greater quality by eliminating inconsistency of workpiece
loading and unloading. |
|
|
| A
workpiece reference location need only be established once. Alignments
for the chuck are established from its centerline, and that data
can be captured electronically and kept in the machine's CNC program.
Work can then be moved from a turning center to a grinder or from
a machining center to a CMM without having to relocate the reference
point. By becoming the new standard in workholding, Unilock
is cutting machine setup time and increasing productivity. |
|
|
| "The
Unilock uses palletization to help manufacturers standardize
the workholding process. It achieves interchangeability in workpiece
fixturing the same as standard tool tapers and spindles have done
in toolholding," says Vacio. |
|
| The
modularity of the Unilock system adapts to workpieces of virtually
any shape or size. Zero point clamping chucks are available in different
configurations for indexing, precision locator bores, custom fixturing,
grid plate fixturing, manual activation, peripheral clearance and
machine table mounting. Standard pallets are offered in steel and
aluminum. |
|
|
| Key
to gaining efficiency from the system is to incorporate the quick
changeover features afforded by knowing the relative location of
the receiver chuck and simply mating the preloaded pallet to it.
Once the location is established, it will repeat for any subsequent
process step that a workpiece will encounter. More process-intense
workpieces reap the maximum throughput gains. |
|
| Palletization
is often the first step in an automation program designed for maximizing
flexible manufacturing potential. It is an integrated part of the
standardization process for automating any shop. However, it also
provides a way for any job shop or manufacturer to develop a systematic
approach to workpiece loading and unloading. |
