Versatile rotary table wet blast systems are available in a range of sizes for automated processing of many different types of components. Target surfaces are exposed to the blast from multiple wet blast guns as the fixtured component, or a group of components arranged on a tree or rack fixture, is rotated at controlled and adjustable speed. The guns are bracketed in position at the correct angles and distances for coverage, and they may be mounted on an adjustable-speed oscillator or a linear actuator. The rotary table wet blast system can also be built with a robotic gun manipulator.
