Today we'll look at a type of joining those of us working with
rivets, adhesives, and bolts might not normally consider. I'm talking
about joining two components to transfer motion or power between them
with the highest possible efficiency. This could happen when you're configuring a drive, setting up a water-jet unit for precision surface prep, or
getting the most out of a machining rig.
Don't forget to scroll down for new products and
upcoming events along with other industry news. We welcome your

A very versatile machining center
The Tricept 9000 made by Loxin in Spain and sold in the U.S. by Hartwig, St. Louis,
can mill, drill, route, deburr and finish, install fasteners and rivets,
and even friction-stir weld with the right tool, according to the
manufacturer. It can also handle optical inspections and touch probing.
The machine uses a two-axis head, three precision actuators, and a pair
of gear drives to get five axes of motion.The design consists of a
central tube and three linear actuators connected to a gimbal support on
one end. At the other end, the tripod struts and tube come together in a
stable triangle around the two-axis rotary head. Independently extending
and retracting the struts moves the head in the X, Y, and Z axes, while
the head rotates 360° horizontally and from 5 to –150° vertically.
High-speed servodrives for the struts give the machine 3,500-ipm rapid
traverse and 2-g accelerations and decelerations. Each of the three
struts has a 39-in. stroke.

The basics of configuring drives
It can be difficult to specify drive components that transform power
from a motor into a form that is useful for the load. The overall design
may dictate use of basic drive mechanisms such as spindles, gearing, or
belts. But the motor or motor/gearing combination determines the
parameters that are optimum.These parameters can include spindle
pitch, gear reduction ratios, and other factors. Drive-system
components, in turn, influence the dynamic response, control quality,
and positioning accuracy.

FLOATING ACCESS HARDWARE
 A captive screw
assembly for permanent installation into panels of any hardness with the
capability to compensate for up to .060"/1.52mm mating hole
misalignment. Their patented MAThread® anti cross-threading screw
technology adds value by correcting off-angle installations, reliably
aligning components, and easily sliding through potentially clogged
internal threads. Type PF11MW (knurled cap) meets "operator access area"
requirements similar to UL 508 and Type PF12MW (smooth cap) meets
"service access area" requirements similar to UL 1950. Universal
slot/Phillips recess is standard. They ideally suit close
centerline-to-edge applications and can be installed on painted surfaces
without marring.

Water jet motion tied to precision
coupling
A machine built for precise, repeatable motion is only as good as
its components. That idea was clear to Jet Edge Inc., St. Michael, Minn., when it designed
a high-rail gantry water-jet.
The machine cuts, prepares surfaces, and removes coatings from metals,
stone, composites, glass, rubber, and plastic up to 20-in. thick.
Servomotors and ball-screw actuators in the cross and side beams control
simultaneous motion in the X, Y, and Z axes, letting the nozzle trace
cutting paths with bidirectional repeatability of 0.001 in. at speeds up
to 1,000 ipm.

Leakproof fluoropolymer fittings
Pureloc compression fittings, for mating fluoropolymer tubing, come
in a dozen styles. The fittings are made from virgin-grade, chemically
inert PFA fluoropolymer and offer unrestricted flow, as well as lock and
sealability. Each fitting consists of a nut, gripper, ferrule, and
body.Purelocs can be disassembled and reused. Available styles
include elbows, straight connectors, tees, adapters, and reducing and
bulkhead types. Sizes range from 1/8 to ¾ in.

Machine replaces chemical priming for
hard-to-treat surfaces
The Enercon Plasma3 VCP surface-treating machine provides
atmospheric plasmas for difficult-to-treat surfaces on wire, cable, and
tubing. The machine eliminates expensive priming and batching as well as
hazardous chemical surface preparations.The machine cleans, etches,
and prepares a wide range of material surfaces that would otherwise be
unresponsive to adhesives and inks. The machine treats conductive and
non-conductive surfaces.

Visible-light and UV-curing
adhesives
Dymax 3000 series adhesives bond polycarbonate, PVC, phenolic,
acrylic, metal, glass, and ceramic. They have low dispensing viscosity,
are VOC-free, and absorb little moisture. The adhesives work with
dissimilar substrates.
The material cures under UV and visible light systems including the
company’s BlueWave LED high-intensity spot-curing device. Here, an
array of cool, surface-mount LEDs in an 8-mm-dia lightguide emit over
2,500 mW/cm2 in a narrow band centered at a 410-nm wavelength. Users can
adjust intensity output from 0% to 100%.
