A wide belt sanding machine from one cast. The construction of a machine in the high end sector had to involve a material which is superior to the steel previously used and which offers fundamental advantages in various points. The material which fulfils the decisive criteria is the mineral cast (concrete polymer). This material developed in the USA in the 1950’s and which has been used in machine con­struction with great success since the end of the 1970’s is now also revolution­izing the characteristics of the wide belt sanding machines from Steinemann Tech­nology. The introduction of the mineral casting technology is opening up a new chapter in the construction of low vibration and temperature-stable machine components. The m ­ in­eral cast is produced from compact vibrated siliceous limestone and a small share of epoxy binder. This siliceous limestone, a natural product from the Swiss Alps is cast in particle sizes of 0 – 16 mm. The advantages compared with steel are clear to see: vibration absorbing (compared with cast iron better by the factor 10) temperature-stable resistant against chemicals favourable noise transmission characteristics solid body non-conductive Vibration excitation by impulse using corrosion resistant Vibration measurement hammer knock. The recordings show the difference between the fading curves. Following a vibration duration of 100 ms the amplitude intensity From a weight point of view the material consists mainly of mineral filling materials with steel is still 38%, with mineral cast (weight share > 90%) and a completely hardened chemically neutral epoxy binder. Sure knowledge is available on the suitability with regard to various stress forms (mecha- Steinemann Technology ASIA nical, chemical, thermal etc.).
