Collet chucks
Command Tooling Systems, Ramsey, Minn.
|
A new line of DR (ER) 32 "Shorty" collet chucks is for tool
shank diameters from 0.079 to 0.787 in. The chucks have an extremely short
projection, so users can maximize workpiece size. According to the company,
tests have shown an increase in machining parameters (feeds and speeds)
of almost three times over conventional collet chucks. The "Shorty"
collet chucks are available in 40 V and 50 V models. The units feature a
nearly flush collet nut that virtually eliminates tool overhang, improving
accuracy while enhancing tool rigidity. Collet pockets are concentric to
the spindle taper to 0.0002 in., precisely placing the tool on the spindle
centerline. Taper tolerances are AT3 or better. These short collet chucks
are particularly suited to small vertical machining centers and multiplex
turning machines.

Machining
centers
Makino, Auburn Hills, Mich. |
The MCC-VG Series of horizontal machining
centers provides simultaneous three-axis machining and slanted hole machining,
accomplished by tilting the spindle at an optimum angle for outstanding
access to the machining point. The tilted spindle on the MCC-VG Series machines
allows for the use of shorter tools to achieve high-efficiency machining.
This prevents the spindle and the tool from colliding with the table. Deep
mold cavities and cooling holes can be machined in the same workpiece setup.
Slanted holes also can be machined continuously at various angles without
changing the setup. The VG comes with Makino's patented through coolant
spindle technology, which the company claims is unique in the marketplace
on an angled-head machine. This technology enhances the speed and accuracy
of drilling angled holes, as opposed to traditional fixed head machines,
due to the natural flushing out of the chips.

Strain sensors
PCB Piezotronics Inc., Depew, N.Y. |
New Series JM240 ICP ground isolated strain sensors use piezoelectric sensing
elements to indirectly measure dynamic and quasi-static stress forces on
resistance welding machinery structures. These strain sensors feature sensitivity
stability, repeatability, high resolution, and long life. A sensor mounted
on a C-frame or actuator with a single screw keeps it out of the current
flow. High electrical noise environments do not affect the ground-isolated
design. Weld quality is directly affected by electrode force and, in typical
applications, the sensor is used to verify that the clamping force has reached
a desired minimum value before the application of weld current. The strain
signal may also trigger weld current, which cuts cycle time by applying
weld current immediately upon reaching the desired force, and avoids electrode
damage due to premature current application. Sensor data may be used to
trend electrode tip wear, capture process deviations, and document the process
to ensure delivery of zero defect product components.

has an increased capacity to generate nitrogen from compressed air. The
manufacturer says the membrane can yield a 30 percent increase in capacity
for nitrogen generator modules, to produce more nitrogen using a fiber of
a given size. According to the company, the high permeability of the membrane
permits production of nitrogen at lower pressures so operators can use less
energy than before. Other claims are that it provides consistent nitrogen
output from 32°F to 90°F, and because its fibers are not affected
by particulate contamination, the membrane has a life of at least 10 years.

Roller bearings
SKF USA Inc., Kulpsville, Pa. |
Carb toroidal roller bearings are useful
in large electric motors (125 hp and above) with their capability to accommodate
very heavy radial loads and compensate for misalignment. Their suitability
for both coupled and belted loads provides users with a single bearing solution
for motors, regardless of mounting method, and can help reduce motor inventory
needs, according to the company. These self-aligning roller bearings combine
design features from several conventional bearing types to promote optimized
performance, reliability, and longer service life. Carb bearings can adjust
for axial expansion of the shaft internally (similar to a cylindrical roller
bearing) and can accommodate misalignment (similar to a spherical roller
bearing). Long self-guiding rollers (similar to needle roller bearings)
maximize load capacity.
