Abstract

The high speed machining (HSM) is now considered as one of the key manufacturing technologies for higher throughput and productivity. HSM used higher rotational speed of the spindle (40,000 min-1 and higher). With increasing high speed spindle rotations raises a number of dynamic forces. Even a small mass unbalance in the spindle and tooling generates tool vibration. Tool vibration shortens tool life and lowers the quality of the machined surface. It is necessary to minimize this vibration by balancing tool and tool holder. The balancing process improves the mass distribution of a cutting tool and its holder, allowing the combination of the two to rotate with the minimum amount of unbalanced centrifugal forces. Machining with balanced tool will provide better surface quality, accuracy and less tool and machine wear. In this study is focused on unbalance cutting tools, definitions, balancing techniques, sources, effects, processes and machineries. The aim of this article was to examine the relationship between unbalance and tool holders used in high speed metalworking machine tools
