A manufacturer of wind mills discovered HEULE's GH/E tool for applying counterbores to a wind mill blade hub, saving over 12 hours per part to produce.

An aerospace manufacturer was machining 30 back spot facings in a component made of Inconel 718 for some years. To do this, the part needed to be set up several times because of the poor accessability of the bores. Countersinks were carried out by a box column drill. For the other counterbores, he used a counterbore tool with a plug-in head for the back bore machining. The process time amounted to approx. 6 hours for one component. His goal was to simply speed up this process. Due to the very demanding material and the difficulty of accessing the machining spots, the customer was very skeptical with regard to new solutions.

A manufacturer of motorsport engines was looking for a cost-effective solution for the application of counterbores.
