Compatible with a minimum diameter of 100 microns. Achieves high precision and high efficiency in microchannel processing.

With the spread of fuel cells and water electrolysis devices, the demand for high precision and mass production of bipolar plates (separators) is increasing. In particular, the press molds used for manufacturing metal bipolar plates require high-precision processing of fine flow channels, high surface quality, and long lifespan. Hufschmied's Bumble-Bi series is an ultra-precision micro tool specifically developed for the processing of press molds for these bipolar plates. With specially designed high-feed end mills, ball end mills, and torus end mills, it achieves both reduced processing time and high-precision machining.
