The vertical Turning Center of the RQX Series of NILES-SIMMONS (Brand of the NSH Gruppe), equipped with one or two ram heads, have automatic tool changing capabilities and are primarily used to machine forged railway wheel blanks. The machines are normally integrated into auto­matic production lines and are loaded by using heavy gantry robots. With the new developement of the RQMC on basis of the RQQ vertical machine, we set on new paths in driving technology. The newly developed radial segment motor Simotics T-1FW68 from Siemens has been used for the first time in machine tool industry, providing a gearless main drive with torques of up to 33 kNm. A multifunctional vertical machining center has been created by integrating a 36 kW / 5000 rpm turn-milling spindle with an HSK100 tool holder which is equipped with a continuously variable swivelling and clampable B-axis with direct absolute measuring systems. The modular design of the RQ series combines a high cutting force with high precision machining that can be used for all types of railway wheels as well as ring-shaped, difficult-to-cut work pieces from aerospace and bearing industries. The automatic measurement of tools and work pieces, combined with various process monitoring systems, ensures successful unattended production. The control system Siemens Sinumerik and Integrate for Production provides software tools that network several units within the production system. NILES-SIMMONS integrates and complements the radial segment motor, delivered in components, by adding a special bearing support and high-resolution measuring system to create a complete faceplate drive with a torque of up to 33 kNm and maximum speeds of 400 rpm. An internal cooling circuit ensures temperature stability and high accuracy. Temperature and vibration sensors monitor the operating status of the entire faceplate drive.
