Machining handpieces help eliminate extraneous rust
Suhner has developed a series of INOX handpieces designed to end the problem of
extraneous rust in machining operations.
Specifically developed for INOX materials processing, the series comprises four
basic models, plus international variants, manufactured almost completely of stainless steel. Identical in structure and function to the company’s other handpieces and
available in 18.5-, 25-, and 32-mm external diameters, the new series fits existing
The handpieces have an elastic bearing that protects the ball bearing and dampens vibrations. The handle sleeves are uncoupled from the working spindle. They
have a cylindrical shape for safe clamping in chucks. An additional mounting aid
facilitates quick, easy change. Air chambers in the bearing promote heat-insulation.
During vibration measurements with carbide cutters, a 50 percent reduction was
measured in comparison with previous handpieces, the company reports.

Burnishing compound designed for mass finishing
Madison Chemical has introduced Tumble Brite EP- 13, a mild burnishing compound
for mass finishing operations. It decreases burnishing time while cleaning oils and
removing oxide and scale, producing a smooth surface with a bright appearance and
luster, the manufacturer reports.
The compound provides excellent lubricity and controlled foam, and it reduces
excessive media-to-media wear, making it suitable for vibratory or barrel operations,
states the company.
With a pH of 3.0 to 3. 5 and a specific gravity of 1.08, the compound does not
contain nitrite, phosphorus, or silicate. It can be used on stainless steel, ferrous, aluminum, zinc, copper, and brass alloys, as well as for deburring operations. When not
rinsed, it provides short-term rust protection for normal operations of steel media.

Abrasive discs’ blended fiber dissipates workpiece debris
Saint-Gobain Abrasives has introduced Norton Rapid Prep™ XHD
coarse and medium discs for aggressive stock removal and blending.
The extra-heavy-duty, nonwoven discs remove weld lines, splatter,
and discoloration and blend surfaces in a single step.
The coarse disc is suitable for aggressive weld removal and surface
blending on steels, while the medium disc is designed for softer metals and alloys. They combine a conformable fiber matrix and premium ceramic grain for improved cut control and surface blending. The
blended fiber dissipates workpiece debris to help increase product
life and maximize shape integrity, the company reports. In addition,
the Clean Bond® resin system prevents smearing and produces a controlled wear rate.
According to the manufacturer, comparison tests have shown a 26 percent higher cut rate with less shedding and two times
more life over a competitive product.
The discs come in 12 sizes offered in three nonwoven types: quick-change discs from 2 to 4 in. TR attachment, hook and loop
discs in 7/8-in. hole and no hole from 41⁄ 2 to 7 in. dia., and speed-change discs from 41⁄2-in. by 5/8-11 fastener to 7- by 7/8-in.
