Siemens has put together a scalable package of coordinated automation and drive components specifically for tapping centers. It consists of the Sinumerik 828D compact CNC with new panel processing units PPU2xx.3 of various performance classes as control hardware and the new variant of the Sinamics S120 Combi drive with triple overload capability. The package is completed with the new Simotics M-1PH8 Premium Performance main motor, which can achieve high speeds.
The productivity of tapping centers can be increased considerably due to the specially coordinated components, the powerful control system hardware, the converter with enhanced overload resilience and the high-speed main motor from Siemens. For example, the spindle can be started up from 0 to 24,000 revolutions per minute in less than one second. This saves considerable time, particularly with tapping center applications featuring frequent tool changes.
The Siemens range is also especially suitable for the increasing number of applications with freeform surfaces and high surface quality, for example cell phone components, which are manufactured with small high-speed cutting (HSC) tools and have short machining times. The tapping center's maximum machine dynamics can be utilized to the fullest extent with the scalable performance spectrum, for example the different control hardware variants PPU 260.3 or 280.3 for the Sinumerik 828D compact CNC.
