ABRS series rotary air flotation using air bearings is by introducing air under pressure in the bearing cavity, since the relief layer of film so as to form a very small gap between the spindle bearing cavity and to ensure that the spindle suspended in the air and stable high-precision rotated. Turntable speed of this structure, high precision, no noise, no friction, no wear, no oil, have excellent speed control performance, anti-collision safety protection features. Because flotation turntable has so many advantages, more and more high-precision air bearing applications to replace conventional mechanical bearings. Sophisticated detection squareness and parallelism and beating and other precision parts for the shaft and disc-type, as well as detection of axis precision manual finishing, or precision machining. Turntable divided into manual and automatic operating mode, Face tilting pans with four degrees of freedom, to achieve precision micro adjustment Face turntable, and can be locked. ABRS series flotation rotating turntable with ultra-high precision, uniform stability, minimal axial and radial runout, and high rigidity characteristics. ABRS series rotary air flotation R & D team by virtue of materials, structures, simulation analysis, technical expertise, constantly optimize the whole turntable result, non-contact air bearing structure to achieve frictionless rotation, so ABRS series rotary air flotation reach corner micron level precision.
