3M offers a variety of solutions designed to reduce abrasive process steps
and increase the number of parts produced per belt. The products featured
here are used for removing scale, gate witness blending and removing
surface imperfections, including light and heavy burrs. Their high
efficiency and long life not only can help reduce the cost of labor and
consumables, but can also speed delivery time.

Abrasives
Derived from patented 3M
microreplication technology, Trizact
abrasives consist of very small,
precisely-shaped three-dimensional
structures distributed uniformly over
the substrate. Unlike conventional
abrasives, which are constructed
from randomly spaced and irregular-
shaped minerals, the uniform
configuration of Trizact abrasives
helps deliver more consistent
finishes with higher cut rates, and
cooler grinding and finishing
temperatures.
The fast, fine, consistent finishes
made possible with Trizact abrasives
help reduce reject rates and improve
worker productivity. In addition,
Trizact abrasive belts can last up to five
times longer than conventional belts.
Conventional abrasives start out sharp, but
dull quickly.
The three-dimensional structures of 3M
™
Trizact
™
Abrasives contain multiple layers
of mineral. As these pyramid-like
structures wear, fresh, sharp mineral is
constantly exposed to the workpiece,
resulting in faster, more consistent cutting
throughout the life of the belt.
