The robust air-bearing spindle EZ-0227 has proven to be particularly reliable for precision and fine machining. Thanks to its labyrinth-sealed exhaust, it is also suitable for wet or lubricated environments. The friction-free air bearing ensures excellent axial and radial concentricity. The integrated Renishaw Tonic FS measuring head is certified for functional reliability. The spindle is powered by a high-performance, water-cooled synchronous motor providing 3 Nm of 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. The spindle can be equipped with a Schaublin W20 collet chuck or a Schaublin SRS W20 concentricity control system, as well as the corresponding clamping cartridges. Other flange configurations are also 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.
