Small, fine and in excellent Baublies quality: these are the burnishing tools which we have developed for filigree applications. We have optimized our many years of know-how in diamond burnishing for the machining of small precision parts and thin-walled workpieces in a compact form. Diamond burnishing tools from the COLIBRI series are always optimally suitable when the peak-to-valley height of filigree workpieces is to be minimized and at the same time the strength is to be increased.
