Abrasives

The abrasive grain consists of a precisely arranged, three-dimensional

structure of tiny mineral particles In use new abrasive particle layers are

exposed continuously. Once the tape is half used, about 85 % of the

abrasive particles are still available.

This produces a smooth, reproducible surface. Trizact™ abrasives are

therefore intrinsically suited to finishing and have, compared to

conventional abrasives, a much longer life and are more economical.

Trizact™

On grinding small corners of the ceramic sintered grain break off. The

resulting micro-breaks in the grain make sharp edges. This process

repeats itself during the entire grinding operation.

This self-sharpening effect increases its life span considerably. Even

with high temperatures and usage the Cubitron™ microstructures retain

their hardness and cutting action. So it is ideal for grinding stainless

steel, titanium and heat-sensitive nickel alloys.

Cubitron™

The individual grains of ceramic Cubitron™ II abrasives are precisely-shaped, uniform in size and arranged at

right angles in the form of small triangles. Naturally Cubitron™ II has the self-sharpening effect of Cubitron™.

Cubitron™ II-grit

Different in size and shape as well

as unevenly distributed. The result

is the abrasive's shorter life span

as well as stress fractures and

discolouration of the material:

Precision-shaped, uniform grin-

ding grains, evenly distributed and

symmetrically aligned. The result is

maximum removal rate, a perfect

surface finish, a quicker, cooler

grind, as well as less material

distortion:

The higher deburring of Cubitron™ II-abrasives benefit all metal-working operations, for example: steel construction, container construction,

welding companies, foundries and forges, that use angle grinders and belt sanders for more removal.

Typical applications are:

• Weld preparation/deburring, cast machining

Quicker deburring and finishing that often needs no further

machining and shortens processing time.

• Chamfering before welding

Quicker grinding processes compared to conventional grinding

products and a longer life span.

• General removal work

Universal on steel, tool steel and non-ferrous metals:

All removal work is faster, lighter and gives a smoother finish.

Benefits:

• Higher, smoother removal

• Up to 40 % time saving potential

• 2 to 7 times longer life (depending on the application process)

• Shorter tooling time due to savings on disc changes

• Less pressure means greater comfort for the user

• Less dust and heat development
