PRODUCT FAQ

What is the 3M™ Trizact™ Cloth Belt 337DC made of?

This belt is made up of a flexible cloth material that offers consistent finishing results.
Can this belt be used on any kind of metal surface?

Yes, it can easily work with various kinds of metal surfaces. It provides excellent finishing performance, especially on tough-to-grind materials like titanium and nickel alloys.
How long does this belt last?

The Trizact technology on the cloth decreases the heat generated while performing grinding tasks which results in reduced dullness of abrasive particles over time leading to its longer life compared to normal belts
. How would I know if my grinding application needs A45 grit size or some other?

As per industrial standards and earlier experiences , A45 grit size works well for medium finish preparation as well as few applications requiring extra force when blending or grinding .
. Where else can I use these set of belts outside industrial operations ?

. Apart from industry you may also find these useful doing DIY projects involving wood , paints/polishing restoration etc .

Long Life, Sustained Cut, Consistent Performance

The 3M™ Trizact™ Cloth Belt 337DC is a durable and high-performing abrasive belt that owes its consistent sustained cut rate to its uniquely engineered "bricks and channels" macroreplicated abrasive structure. The uniform abrasive "bricks" keep fresh cutting mineral constantly at the working surface, while the "channels" sweep debris away to discourage loading and keep the substrate clean.

The "bricks" consist of layers of mineral and grinding aid, up to 4 times as much as conventional aluminum oxide belts of the same grade. These dense layers of abrasive mineral lead to extra-long life and extremely consistent performance. The grinding aid protects heat-sensitive alloys from damage and reduces rework. Trizact belts start sharp and stay sharp, delivering a consistent cut that can often consolidate or eliminate process steps. In many cases, Trizact™ 337DC has the capacity to grind and finish in one step.

Microreplication: Engineering Surface Geometry

Building upon the principles of microreplication, 3M scientists developed larger, more diverse abrasive structures —cubes, spheres, ridges — identical in shape and optimized for a variety of applications. Microreplication allows 3M to design abrasives with varying shapes and formulations, to control the level of breakdown, cut, finish, and life.

These abrasive structures are arrayed precisely and uniformly across a film or cloth backing in a pattern calculated to deliver sustained cut rate and eliminate belt-to-belt variation.

Made to Tackle Difficult Metals

Trizact was developed especially for finishing more difficult processing materials like titanium, cobalt, stainless steel, as well as all exotic alloys in the aerospace, aviation, and medical industries. It is also effective for finishing applications on carbon steel, copper, bronze, aluminum, composite materials, and synthetics.

Recommended Applications

Use for dry intermediate finishing, blending, scratch refinement, or final dimensioning on robotic, semi-automated, automated, off-hand equipment, and portable file belt tools. Use Trizact™ Cloth 337DC belts with:

Medium hardness contact wheels (50-70 Shore A)
Rubber contact wheels
Smooth face to gentle serrated contact wheel

To prepare drawn carbon steel truck exhausts from rough to pre-plate finishes in as few steps as possible, we used a grade sequence of A100, A65, A30. Trizact™ 337DC outlasted a competitor by 2:1. For blending, final dimensioning, and finishing of turbine engine components, the grade A45 Trizact 337DC belt outlasted a competitor's belt by 4:1 times and produced a finer finish.

Creating More Perfect Surfaces

Microreplication is only one of 3M's platform of core technologies. Its perfectly calibrated arrays are designed to give materials new physical, chemical, or optical properties. The science that makes 3M's structured abrasives wear more evenly, last longer, and provide more pristine finishes on delicate components like medical implants is also the science that makes traffic signs brighter, and exterior building illumination capture and reflect light more brilliantly.
