Product description

The robust air-bearing spindle EZ-0227 has proven to be particularly reliable for precision and fine machining. Due to the sealing air exiting via a labyrinth, it is also suitable for wet/lubricated production environments. The friction-free air bearing enables excellent axial and radial concentricity. The integrated Tonic FS measuring head from Renishaw is certified for functional reliability and allows a maximum speed of 3,600 rpm. The spindle is driven by a powerful water-cooled synchronous motor with 3 Nm torque. With radial and axial load capacities of 425 N and 700 N, respectively, the spindle is ideal for high-precision turning, drilling and grinding processes. In the standard version, the spindle is equipped with a Schaublin W20 collet chuck or a Schaublin SRS W20 runout control system; other flange shapes and clamping systems are available on request. Two integrated rotary feedthroughs for compressed air/vacuum can be used to operate the pneumatic release unit and to blow off chips.

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.
