New
Unilock Model 176 Chuck Has Expanded Diameter
For High Torque, Rotary Table, Heavy Duty Applications |
| |
| ELK
GROVE VILLAGE, IL—A new, large Unilock Model 176 quick
change clamping chuck features an expanded diameter to provide
additional clamping
surface, making it very adaptable to user applications in custom
fixture designs and excellent for high torque, rotary table and
heavy duty applications, BIG Kaiser Precision Tooling announced. |
| |
| Model
176's large Z reference plane (176 mm or 6.93") accepts
standard SB 40 mm clamping knobs and easily integrates into
base plates and
custom fixtures. BIG Kaiser offers an optional turbo boost for
heavy duty applications and optional reference pin features for
mono applications. |
| |
| Model 176 is the
chuck of choice for use on tombstones, fixture plates and custom
work holding applications. The unique notch in the chuck allows
the customer a choice of a 25-mm pin or key to orient the fixture. |
| |
| “The Model
176 achieves maximum clamping force when the chuck is closed
with the assistance of air pressure. It has the high clamping
force necessary to outperform pneumatic/hydraulic systems,” says
Gerard Vacio, BIG Kaiser’s Product Manager, Workholding
Systems. |
| |
| The system standard
Unilock 40 mm clamping knob can be attached directly to work
pieces or fixtures with up to a 16-mm thread. The easily mounted
clamping knob provides affordable accuracy and rigidity. The
spring-based mechanical clamping system of the Model 176 supports
an air boost system to increase clamping force by up to 30% over
spring retention alone. This boost in clamping force allows for
an increase in the retention thread size. |
| |
| 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 center line, 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. |
