Abstract

Precision machine tools are expected to operate at higher machine speed to produce precise products. Hence, its structures must have high structural stiffness and high damping along with dimensional and geometrical stability. Granite is the material used for metrological and precision machine manufacturing applications. Granite is also used in some of the high accuracy machine tool manufacturing. Considering the natural properties and limitations of granite a new emerging material named Epoxy Granite is evolved. In this paper, Epoxy Granite properties using Indian Black granite are studied. In particular, the maximum load-bearing and density of epoxy granite are focussed. Also, the combination which is best suited for the applications can be easily dragged out. Density is compared with maximum load-bearing and their relation is also put forward to simplify the selection process of epoxy granite.

Highlights

  • Designing process of machine component involves manystages; it starts with defining functionality and performance requirement, to the testing of individual component and testing the complete machine

  • It can be concluded that 16% epoxy gives greater density than any other epoxy percentage in the mentioned combinations

  • Graph I is clearly indicating that density is directly proportional to the Max load

Summary

Introduction

Designing process of machine component involves manystages; it starts with defining functionality and performance requirement, to the testing of individual component and testing the complete machine. Epoxy granite is a low-density material, owing very good dynamic properties due to which it is the most preferred material in the machine tool industry. A recent study on epoxy granite is about finding the different material properties like its compressive strength, flexural strength, modulus of elasticity, coefficient of thermal expansion, damping capacity, required for machining.
