BTA deep hole drilling is required for a variety of drilling applications with high length-to-diameter-ratios and high qualities. It is one of the latest machining operation in the production chain. Due to the high components value, high process stability and product quality is necessary. One of the most important quality features is the bore´s straightness deviation. In order to compensate this straightness deviation during the drilling process, a compensation unit has been developed. In addition, the influence of the compensation unit on the straightness deviation has been investigated in FEM simulations.
