BT50/BP
The JIS BT MAS 403 is very similar to the SK connection, both in shape and usage. Its origin is Japanese and it had great diffusion before the HSK introduction. For this reason it is easy to find BT cones equipped on CNC work centers coming from Asia. BT usage is comonly limited to operations under 12.000 RPM, unless provided with a special extra balancing process. The connection with the electrospindle is made through a pull stud screwed on the top of the cone.
The BP configuration is a further development of the original BT connection. It is studied to fill one of the topical issues within the BT system: in fact, BP ensure the HSK “face-to-face” contact, improving the concentricity, reducing vibrations and extending the spindle components lifespan.
