ELKA Elastic

The call for complex and integrated technical processes is continuously increasing.

Modern grinding technology is no longer limited to the use of conventional grinding wheels with common bond types. Today, elastic abrasives have also become indispensable as production tolerances become tighter, process times briefer and the demand for technically and optically perfect surfaces greater.

ELKA is continually developing new processes in the laboratory that can be brought to the serial production lines of our customers. This results in product solutions tailored to the individual grinding and polishing applications of our customers. We provide solutions for metal finishing with ELKA-Elastic, glass Ffnishing with ELKA-Vitro and everyday problems with ELKA-Sparkle.


ELKA Vitro

Elka Vitro glass polishing wheels have matured into leading edge products.

The E300 series scored particularly well in Italy, the home of glass polishing.

Comprehensive tests resulted in the best practice wheel combinations shown in the table (coming soon).

These recommendations were tested largely at machine dealers and thus represent a sound basis.

We make a distinction in practice between single- and double-sided polishing machines.

Single sided:

In single-sided polishing, the glass, which is usually in a vertical position, is held between 2 rubber chains and transported across the polishing wheels. These wheels come into contact on one side with the glass pane. The process is carried out with water cooling.

Depending on the machine, there are 1 to 4 polishing stations which are equipped with different tools (see Table (Table coming soon)).


Double-sided grinding machines are mostly arranged in one angle combination and are used for larger volumes, e.g. in the furniture industry, in façade construction and for solar technology, etc.

The grinding pressure can be minimised using this machine type in contrast to single-sided machines. However, even in single-sided machines, the pressure required by ELKA polishing wheels can also be reduced compared to competing tools on the market. In general, 80% of ELKA Vitro applications require around 50-60% of the pressure of that used by competitive tools.
