Product description

The EZ-9570 air-bearing spindle is designed for high- precision grinding applications and reaches speeds of up to 20,000 rpm. Due to the sealing air exiting via a labyrinth, it is also suitable for wet/lubricated production environments. The synchronous motor is available in two versions: with a speed of max. 20,000 rpm at a torque of 2.6 Nm and with a speed of 12,000 rpm at a maximum torque of 3.2 Nm. Housing and rotor are water-cooled. The standard version of the spindle is supplied either with flange mounting and centering collar or with an HSK 50-C clamping system. Other flange shapes and clamping systems are available on request.

Applications: Precision and fine machining, turning of optical glasses and technical optics, glass milling, grinding/polishing of optical lenses and displays for cell phones and tablets, micro-machining of optical and medical products.
In general: For applications with high demands on dynamics and precision.
