Trizact™ microreplication

Microreplication is the repeated forming of microscopic, perfectly calibrated three-dimensional structures. This technique
guarantees perfectly preformed and calibrated abrasive grains in a pyramid shape. These pyramidal abrasive grains are identical in height. This ensures a limited penetration of the abrasive grains in the work piece, eliminating the danger of uneven edges or deep scratches.

Trizact™ macroreplication
These are three-dimensional structures uniformly distributed over the entire surface. These are made from compressed Trizact™ grains that guarantee consistent and predictable material removal and finishing.

Area of application
Trizact™ has been specially developed for finishing more difficult processing materials such as titanium, cobalt, stainless steel,
as well as for all exotic alloys in aerospace, aviation and medical industry. We also have very successful applications for
finishing, copper, bronze, aluminium, composite materials and synthetics.

Please note: Trizact™ has been developed for finishing work; it is not a deburring product.
The 237AA and 217EA (microreplication) are characterised by their capacity to perfectly finish materials with fewer steps, little working pressure and a constant and replicable finish.
The 337DC and 953FA have the capacity to grind and finish in one operation.
The 217EA, 237AA and 337DC have been developed for dry use. The 953FA has a waterproof support and has been developed for use with coolants.



Properties

- abrasive grains with equal height
- always the same number of abrasive
- grains available
- always the same shape and depth of
- abrasion
- equal wear of the abrasive grains always
- new, identical abrasive grains available
- higher stock removal at lower pressure

Benefits

Application recommendations
The belt speed, transit speed, working pressure and hardness of the contact wheel are crucial parameters for a good result. Moreover, a change in one parameter also affects the working of the other 3 other parameters and consequently, the result of the finishing and the performance. When in doubt, consult your Cibo application-expert.

  Belt speed

10 - 15 m/s
20 - 25 m/s

Working pressure
It is best to keep the working pressure low. Ideally, this should be between 0.6 and 1.5 kg/cm², without however, going above 2 kg/cm². A higher working pressure will negatively influence the lifetime of the belt but increase the removal speed.

Contact wheel
Abrasion and structuring: 40 to 65° Shore without or with small grooves. Finishing or polishing: 20 to 40° Shore with a full or, ideally, a layered wheel. A softer contact wheel produces a better Ra-value.

Transit speed
It is best to keep the movement of the operator with the machine or the working piece as regular as possible. The more regular it is, the more uniform the finish. For an automatic transit, Cibo recommends a speed of approximately 4 metres per minute.

 

237GR - Trizact™ grip discs
The perfect positioned pyramid structure of Trizact™ removes TIG welds with ease.
The 237GR also leaves behind a very fine scratch structure, which is perfectly suited for further processing into a brushed structure and high
gloss finish. The high quality of the pre-polish saves you time and costs.
