Ceramic Horizontal Arm - HC90 The HC90 range of horizontal arm CMMs provide unequalled performance in speed, accuracy and repeatability, continuing LK’s highly innovative approach to CMM design. The outstanding performance owes much to the ceramic guide ways and air bearings used in the construction. Stability at high velocity and acceleration cannot be maintained using outdated materials such as steel or aluminum with mechanical bearings. Offered in rail or table-mounted configurations, the options of single or multiple columns are available with sizes starting as small as 1000mm x 600mm x 400mm and ranging up to and above 20m x 1.6m x 3m. Repeatability values as low as 1.9 microns are achieved with vector velocities of up to 50 meters per minute. The HC90 configuration provides unique access to the measuring envelope and can be supplied as sub-floor or floor level installations, or as part of a fully-automated FMS cell with automated component loading and environmental enclosures. Combined with our own 3D measuring software CAMIO, the HC90 provides the complete inspection solution.
