PDK Design and Grinding was founded on innovative design of pelletizer rotors and knives. Precision multiple axis grinding is vital to the performance of our service center activity. Whether it’s a first time preparation of a new product or re-qualification of a serviced item, PDK offers a superior skill level to assess your application, offer a solution and execute the configuration best suited for your requirements.

State-of-the-art 6 axis CNC ultra-precision machine tools capable of simultaneous multiple axis grinding, allow generation of the actual tooth profile during re-sharpening as well as during manufacture of pelletizer rotors. Profile generation of the cutter teeth provides optimum performance of a cutter to your specific application and promotes longer rotor life through minimal stock removal.
