CNC Indexing Turntable Shot Peening Machine

Automated machines for repetitive, high volume applications that demand quick and accurate processing of multiple parts at a time.


Reduced Setup Times

Motion control reduces costly nozzle setup time, and time cycles.


Precise Control

CNC motion allows a nozzle to follow the contour of a part for consistent and true intensity and coverage throughout the part.



Rotary table machines offer customers repeatable and stable systems for a wide variety of parts.

Highly automated for high production.

Our CNC Indexing Turntable abrasive blasting machines offer customers a high-production rate for similarly sized parts.

The operator loads a fixture while a part is processed inside the cabinet, and the parts rotate in front of a series of nozzles that can be mounted on a combination of axis motions. After the cycle time is over, the doors open and the main table indexes exposing the finished parts to an operator for unloading/loading.

Variable Speed Direct Drive

Our CNC Indexing Shot Peening machines incorporate a variable speed direct drive system that monitors speed and rotation. This direct drive rotation eliminates the need for bearings and pulleys in the peening/blasting strike zones, thus cutting down on wear.

Flexible Media Delivery

The media delivery system can be either gravity assisted suction, direct pressure or continuous direct pressure.

The shot recovery system includes a cyclone reclaim, rigid urethane shot recovery duct, screen classifier and an automatic reverse pulse cartridge dust collection with steel ducting and fan silencer for clean, quiet operation.

Nozzle motion can be either stationary, vertical, or multi-axis, including nozzle tilt and yaw. Motion programs are controlled by CNC processor.

CIMCAP Process Monitoring Software

IPS also offers our CIMCAP process monitoring software designed for peening and blasting operations. Process parameters such as airflow, air pressure, recovery system and machine interlocks are constantly being monitored. If any of the process parameters fall outside the acceptable limits, the machine will automatically interrupt the peening process and alert the machine operator and process engineer.

Robotic Arm Shot Peening

Articulating arm robotics can be added to the interior or exterior of all IPS machines. Normally this type of robotic motion is specific to an application, such as plastic media blasting, or a specific motion that a CNC-gantry robot cannot provide. Articulating arm robots are historically cheaper than CNC-gantry robots, but can be more expensive to repair should wear occur inside the enclosure. Articulating arm robots also require larger enclosure sizes to accommodate the robot motion. The main benefit of an articulating arm robot motion is speed and reach. Systems can also be integrated with other loading robots and multi systems tasking.

Robotic articulating arm machines offer users a fast nozzle motion for larger parts that need quick cycle timers. Customers may choose the robot of choice. Another benefit to some customers is the familiarity of robot programming. Machine enclosures are custom built to allow the robotic arm to fully move to peen or blast the users part.

    Frequently Asked Questions


    Why should I shot peen parts?

    Shot peening enhances parts by replacing tensile stress. Tensile stress can cause parts to fail, with compressive residual stress, which are strong and part of a design and reside in a part. Well know examples of residual stress designs are the Colosseum in Rome and the Hoover Dam.

    Will extra peening make a part even stronger?

    No, you can actually damage the fatigue life of a part by overpeening and the best way to control the peening to specification is through CNC control.


    How can a single robotic nozzle be better than a batch or multi- nozzle machine?

    A single nozzle robotic machine is better and faster than batch and multiple nozzle machines since they will cover the entire designated area to precisely 100% coverage. Batch and multi-nozzle machines can strike the same place to 300% or 400% coverage in order to get all areas to 100%, ultimately weakening the part AND increasing production time.
