This integrated two-axis rotary gimbal assembly provides high-speed machining capabilities for complex 3-D part geometries. This precision-aligned system allows accurate positioning on a hemispherical surface. Multiple frame sizes with direct or gear-driven options provide a range of load carrying capability. This gimbal has gear-driven tilt axis configurations to meet the performance requirements of specific applications, and stepper motor or servomotor versions provide the operating speed and accuracy. The tilt axis can be equipped with a brake to hold axis position when power is removed. For large-load applications, the gear-drive units provide higher continuous torque output, while the drive mechanism limits motion in the power-off state.
