DYNAMIC PROPERTIES OF DEVICE BODIES MANUFACTURED OF POLYMER CONCRETE
Jürgen LANG
Abstract: The paper shows the dynamic properties of device bodies manufactured of polymer concrete in order to show the advantages of this material in comparison with grey cast iron. Polymer concrete has many interesting material characteristics for workshop facilities, two of which are the good vibration absorption and the relatively low specific weight. On the basis of these properties, device base plates manufactured from grey cast iron may be replaced with base plates manufactured of polymer concrete. Overhanging device bodies may be constructed with an extended wall thickness at a weight comparable to grey cast iron device bodies. The second part of the paper is concerned with the application of the polymer concrete device bodies in milling machining. The behavior of the polymer concrete device bodies was tested with respect to surface quality, specifically the surface roughness of machined work pieces. Different settings were investigated to identify the influence of cutting speed and feed rate.
Key words: polymer concrete, vibration damping, workshop facilities, grey cast iron.
