Mineral casting (polymer concrete composite) is a material that can be used n the most diverse fields of application. Historically, the greatest use is in the machine tool industry, where its share of the market is constantly rising. Developing markets in which SCHNEEBERGER mineral casting technology is active are the optical sector, the packaging industry, medical technology, solar technology, the printed circuit board industry, inspection machinery and Pick and Place machines.

A single cast.

Mineral casting from Schneeberger offers unbeatable advantages, which come to the fore in the optical industry.

Anyone who works with optical components and surfaces, such as industrial lenses or glass for spectacles, cannot afford to cut corners when it comes to surface quality, precision and productivity. After all, their customers’ sight depends on it, as does the ability of machine manufacturers to compete in the optical industry.
Powerful machines can manufacture well over 100 spectacle lenses per hour, with consistently reproducible levels of quality. In order to realise the high engineering dynamics and required product geometry while maintaining the utmost precision, machine constructors require a machine bed that has exemplary vibration dampening and thermal stability, such as can only be achieved by mineral casting.
This means we are an indispensible partner for manufacturers of production equipment, not only for high quality industrial optics but also for fine spectacle lenses.
Schneeberger produces its mineral casting in a cold casting process using minerals and epoxy resin. Thanks to the especially perfected production methods, we can achieve exceptionally flat and parallel reference surfaces, whether for guideways or other precision components such as measuring scales or linear motors.
As Schneeberger manufactures both mineral cast constructions and linear bearings, we are able to adjust the bearing support surfaces so that they are an optimum match for each bearing type and for the specific application. This ensures the most linear, parallel and flat operation possible for linear movements, resulting in optimum technical and economic solutions.
