Hexagon Launches New Rotary Tables for Optiv Performance Multi-Sensor CMMs

Hexagon Manufacturing Intelligence has extended the accessory range for its Optiv Performance and series of coordinate measuring machines (CMMs) by adding two new CNC rotary tables and the Optiv Dual Rotary CNC stacked rotary tables as options, substantially widening the application potential of the multi-sensor machines.

The use of the fully-integrated CNC rotary axis increases the overall inspection performance, especially when measuring rotationally symmetrical parts. Such work-pieces can be completely measured in a single setup as features distributed around the circumference of the part can be precisely rotated into a position which is optimal for the multi-sensor measurement. The PC-DMIS measuring software takes the rotation of the workpiece coordinate system relative to the machine coordinate system into account. The Optiv Dual Rotary option allows the entire rotary axis to swivel on an additional axis so the sensors can reach geometries that are inclined to the longitudinal axis of the work-piece.

The tactile measurement of prismatic workpieces on a rotary table or the stacked rotary tables also offers improved efficiency through the rotating and swivelling movement, which makes complex geometries easily accessible with only a few simple styli configurations. This reduces the necessary probe changes as well as the number of axis movements within the measuring volume.

The new mechanical bearing rotary tables for the Optiv Performance machines provide high-precision rotational accuracy. Two sizes are available, offering different maximum torques (2 Nm or 10 Nm) and normal centered load capacities (900 N or 1800 N). Depending on the version, self-centering three-jaw precision chucks for diameters between 2 mm and 125 mm are optionally available. With the Optiv Dual Rotary option, two rotary tables are combined to enable two-axis rotations.

“We have extended the range of applications for the Optiv Performance with the automatic work-piece rotation within one measurement routine,” says Wolfram Fröhlich, Business Unit Director for the Vision Unit at Hexagon Manufacturing Intelligence. “With up to two additional rotary axes, our customers can make optimum use of the available measuring volume of the machine and perform complete multi-sensor measurements of complex components without re-clamping.”
