The new RFID tags are designed to be mounted in the end of a tool holder retention knob. This retention knob is then screwed into the top of the tool holder to provide not only a handling point for automatic tool changing, but also a reliable and repeatable place for reading a Tool ID tag in existing Mazak machining centers. These tags include a center hole compatible with the cooling and sealing apparatus that allow cooling fluid to pass through the center of the tag and retention knob used by Mazak machines. These tags are made to withstand the higer pressures and centrifugal forces present in this mounting position. T.J. Davies’ retention knobs are the highest quality retention knobs on the market. For over 50 years, we have been second to none. The retention knob or pull stud is a critical component to the tool holder’s performance and cutting tool life. We utilize 8620 and 9310 alloy steel for its high tensile strength to withstand strong centrifugal force, high load force, high feed rate, and difficult-to-machine material in the era of current CNC machining environment. As the forces exponentially increase, precision and strength in machining and tooling requires a higher quality of the retention knob or pull stud connecting the spindle to the tool holder. To maintain the tight tolerance of critical dimensions on a retention knob, we inspect our parts throughout the manufacturing process. We utilize batch production so that each retention knob has written inspection data and traceability to each batch. Additionally, the threads on our retention knobs are cut, which provides higher strength and excellent thread quality. Each retention knob is carburized to 58-62 RC. The finish on our retention knobs is 32 micro or better with a black oxide finish.
