providing increased precision when setting the stroke control. This feature is especially helpful when aligning and positioning tools and while performing regular machine maintenance.
New Scotchman snap-ring-removal tools for #20 punches simplify an otherwise tedious task, according to company offi- cials. The tools are sold separately or can be included with the purchase of a #20 punch and die package.

Small Internal-Mix Spray Nozzles Coat, Cool, Treat and Paint
New 1/8 NPT small internal-mix spray nozzles from Exair atomize fluids at speeds to 42 gal./hr., with small atomizing nozzles mixing liquid and air inside the cap to produce the fine atomization. Internal- mix nozzles can be used on liquids with viscosities to 300 centipoise.
The nozzles are available in narrow- angle round pattern, wide-angle round pattern and flat fan pattern, and can be used to coat parts in containers, cool lam- inates, or apply paint and lubricant. Stain- less steel construction adds to the nozzles’ durability and corrosion resistance.
Exair atomizing nozzles also are avail- able in 1⁄4 and 1⁄2 NPT, and in a variety of flow patterns and liquid rates. Also avail- able: external-mix and siphon-fed atomizing nozzles, as well as patented no-drip ver- sions of every atomizing nozzle.

Punch Press Tooling Ideal
for Adding Strengthening Ribs
Mate Precision Tooling’s Rollerball punch press tool allows users to quickly and simply create stiffening ribs and decorative beads in sheet metal without secondary operations. The tool forms a rib by pinching the metal between two omnidirectional ball bearings in the upper tool assembly and a single ball bearing in the lower assembly. The shape of the rib is created via the punch press programming system and can be placed anywhere on the part surface.
“When material is deformed to create the ribs, the material thickness increases, strengthening the material,” explains John Ripka, Mate Precision Tooling application specialist. “The tool allows part designers to reduce sheet metal thickness without compromising the strength and rigidity of the final product. These ribs are essential when using minimum material thickness to control costs. Also, these applications allow fabricators to eliminate secondary operations, resulting in material and labor cost savings with reduced production time.”
Use the Rollerball tool in machines that can hold down the ram while simultaneously moving sheet around the X and or Y axis. When used in machines with accurate stroke control, a simple adjustment to the machines’ stroke length creates a deeper or shorter form. In other thick-turret machines, using the Mate Rollerball in a Mate Ultraform holder offers simplified adjustability by changing the length of the holder with a few clicks of the tool.
Using the Rollerball tool offers a better option than using a standard forming tool to make strengthening ribs, according to company officials, noting that standard forming tools may require tens to hundreds of hits and several minutes to produce strengthening ribs over the length of a sheet. The Rollerball can reduce machine time to a few seconds. Mate Precision Tooling: www.mate.com
Handheld Air-Plasma Cutter Pierces 5⁄8-in.-Thick Metal
Thermal Dynamics, an Esab brand, has debuted the Cutmaster 58 handheld air- plasma cutting system, a reintroduction of the Cutmaster 52 that has been upgraded to include the SL60 QD (quick-
disconnect) 1Torch as standard.
The power-to-weight ratio of this
60-A, 43-lb. unit is ideal for fab-
ricators, general and mobile
contractors, farmers, mainte-
nance and repair personnel,
and truck/autobody shops,
according to company officials.
It can pierce 5⁄8-in.-thick mild
