Custom Designed Robotic Cell for Shot Blasting

A local client approached MJ Engineering to design and install a custom robot cell for the purpose of automatically handling small parts for the purpose of shot blasting one surface in a blast cabinet. The cell incorporates a circular pallet conveyor and a blast cabinet. The shot material and shot process can be modified to allow for different part finish specifications.

The robot uses a custom designed magnetic EOAT (End of Arm Tool) to pick multiple parts from a pallet and present them into a blast cabinet for finishing. The operator loads one of 12 pallets with a tray of unfinished parts then selects the specific processing program from the touch screen operator panel.

The pallets automatically index into and out of the cell as they are processed by the robot and the blast cabinets.

Project Description

This custom designed robotic cell is used for shot blasting a surface finish on very small parts.

Capabilities Applied/Processes

Cell Design

  • Conception of cell that meets unique production requirements.
  • Create SolidWorks© 3D models of cell concept

Tooling Design

  • End Of Arm Tooling (EOAT) Design Integrated w/ a custom designed magnet lifting mechanism.

Operator and Maintenance Training


Utilizes FANUC© M10iB robot with R30iA controller.
Parts are delivered into the cell via the circular pallet conveyor.
Ability to control all blast variables:

  • Duration
  • Presentation (angle and distance)

Provides a fully automatic processing cell that requires minimal operator involvement.
Ability to pick variable part sizes for presentation to the blast.
The operator has easy access to the process control via the custom programmed touch screen operator interface panel.
