A comparative examination of in vivo measured revolutions proves that turbines with torque have a 100% wider usable revolution band than conventional ones. The resulting increased grinding capacity may seen at first sight as a positive effect, but is combined with a more than proportional increasing heat development. Literature, research and own considerations allow the statement, that revolutions used today and the possible pressures make a sufficient cooling of the grinded surface a problem. In order to reduce the recent distinct increase of preparation damages, a reduction of the possible exerted pressure as well as the current level of revolutions must be called for. In the same way as usual in the production industry the optimum rate of grinding capacity to heat development should be determined for each grinding instrument. In this respect not only the turbine is a step into a wrong direction.
对体内测量转速的比较研究表明，带扭矩的涡轮机的可用转速范围比传统涡轮机宽100%。由此产生的磨削能力提高乍一看可能是一个积极的效果，但同时伴随着热量产生的超比例增加。文献、研究和自身的思考表明，如今使用的转速以及可能的压力使得对磨削表面进行充分冷却成为一个问题。为了减少近期明显增加的预备损伤，必须要求降低可能施加的压力以及当前的转速水平。与生产行业通常的做法一样，应为每种磨削器械确定磨削能力与热量产生的最佳比率。在这方面，不仅涡轮机是朝着错误方向迈出的一步。
