There are three major issues to think about when considering the proper toolholder for a high-precision application: (1) rigidity (2) accuracy (3) balance.
Much has been said in the industry today about the issue of balance, but it is important to consider the combination of all three of these issues when providing the best solution. This involves both of user and machine maker to set-up and maintain a proper quality of the machine, that the work result's quality might be satisfactory

When first designing a machine, it's ability must be defined carefully, so that every components are designed, or chosen according to the final requirements. Every machining purpose had its own characteristic, which will affect the whole machine design. The other certain thing is that spindles, related very close to the toolholders, which will hold significant part determining the quality of machining works
A machining job generally divided into two major direction : high-speed machining, or high force machining. Older machines are usually high-forced, given tough characteristic, bulky, stiff, highly capable of high metal removal rates, but usually slower. The newer machines lately grown toward high-speed, compensating low metal removal rates with a very fast feeding, so that the machining time would not differs much. High speed machines are generally more precise, since it is mostly used for contouring, that needed smooth surface as the result.
