Maximum performance in machine tools
Siemens offers the perfect portfolio of motor spindles that deliver maximum productivity and precision and ensure optimum performance and product quality. Mechanically built-in-motor solutions are extremely compact and achieve maximum rigidity, a requirement for achieving maximum speeds and exact concentricity.
Looking for motor spindles for use on milling machines and machining centers? Your first choice should be Siemens’ compact water-cooled 2SP1 motor spindles. In contrast with externally driven motor spindles, we offer a high degree of compactness, precision and productivity. Our compact "all inclusive" spindle solution will provide you with additional benefits, too. For example, the built-in motor means fewer parts compared to a belt drive solution. And the sensor technology for indexing and monitoring is built in. In short, the 2SP1 is the economical standard for your motor spindle requirements.
