Principle of XINTECH MasterFinish blasting method

In order to achieve specific and defined surface, there are various ways which can be applied. One of them is so-called "blasting method". Generally, the physical interrelation of kinetic energy is used in this method. Mass x speed squared equals energy. Different blasting material in form and size lead to different results. This specifically applicable differences are used as basic technique in the XINTECH blasting machines.

Choice of blasting material

diverse Strahlmittel The blasting materials may consist of different substances, thus they have difference specific weight. This fact can be also applied to various results on the surface. A mixture of blasting materials, which show generally different specific weight of the each component, can achieve several requirements on the surface in single working step by using different impact energies. The choice of blasting material and possible mixture depends primarily on the requirements of surface and its intended use.

Stepwise treatment of surface

The applied blasting material varies generally in two groups; the non-abrasive and the abrasive. In the most of cases, both types show different topography (sharp of round).

1st step:

For the preparation of surface, so-called the first step, a sharp and abrasive blasting material is used mostly. Machined surfaces are contaminated in different ways, so that they are not suitable or unusable for the further process or the intended purpose. The contamination or particles which are not properly bounded with the substance should be removed exactly out of the non-uniform surface, without changing the preset geometry.

2nd step:

After homogeneous surface has been achieved by the first step, it can be now optimized. By removing of contamination and loose inclusion, originated from various working methods, numerous pits and points arise inescapably. In the second step, the pits are smoothed specifically, so that the new surface is uniformed.

3rd step:

In order to achieve special attribute for any surface, a third step can be applied with coated, non-abrasive granulate or granulate which is embedded with substances to get intended contamination. This intended contamination can provide e.g. better sliding effect or longer lifetime of the parts.

Wide-range experience over many years of our application engineers are always at your disposal. We will be also pleased to carry out trial and surface analysis in our own laboratory. Surface treatment of an issue of trust and requires wide knowledgt.
