BAHMÜLLER employs a concept in which we replace previously used ceramic grinding tools for match grinding of jet needles for diesel injection with CBN.
The following convincing arguments were ultimately decisive in the optimizations that were achieved:
The challenges BAHMÜLLER faced were successfully mastered: the effect in production was extremely drastic, and BAHMÜLLER could change over the existing "old machines" to the new technology with
The deflection compensation during grinding, by means of the piezo "driven" tailstock, is now
used for nearly all slender "long parts" for cycle time reduction and quality increases.
The process has since been further optimized so that the conical shape of the guide bore is modified during match grinding of the ground guide part, which allows for entirely new gap dimension reductions.
