Introducing SARA™

(Six Axis Robot Arm) Resurface System...



Saving through Technology & Safety

Unique Advantages of SARA™

• Designed specifically for ALL cabin windows to remove scratches and crazing
• SARA™ Resurfaces windows without removal from airplane
• Typical window can be resurfaced 80 to 340 times with the SARA™ System extending window life
• Save time and cost of window replacement
• Aircraft downtime to resurface all cabin windows is less than two days
• Resurfacing windows to equal or better than OEM quality

How SARA™ Works:

SARA™ works in-situ on the fuselage. It is not necessary to remove the window to resurface it. The combination of the six axis robotic arm, computer, proprietary end of the arm tooling, orbital motor and variety of kits: working in unison and perfect coordination enables SARA™ to resurface a window repeatedly while obtaining a predictable and consistent result. The window will always be resurfaced and polished to optical quality without distortion. The process can be repeated many times without exceeding minimum thickness allowed by the manufacturer.

​

The computer controlled robotic arm, proprietary  “end of arm” tooling, orbital motor are capable of”

1. X axis (move up and down)
2. Y axis (move left and right)
3. Z axis (move in and out)
4. Pitch axis (tilt forward and back)
5. Yaw axis (tilt side to side)
6. Roll axis (twisting motion)

SARA™ Robot Arm

SARA™’s unique ability to duplicate the movement of the human arm with precise repeatability (.0001 inches), allows its “end of arm tooling”and abrasives to follow the window’s contour and symmetry ensuring constant pressure against the window.  A load cell shuts down the system in the event of disruption or variation.

SARA™’s Computerization

The “touch screen” pendant or keyboard allows the operator to input the window type into the system, thus allowing SARA™ to recognize its radius and contour. A predetermined “work pattern”, consequence of extensive testing, is used to ensure a consistent and predictable outcome.

SARA™ Working “In-situ”

SARA™ adheres to the aircraft by utilizing a vacuum system and works “in-situ” or in place on the fuselage, thereby eliminating the need to remove the window. Performing the work “in-situ” will result in vast savings from the traditional methods of “removal and place or repair”.

​The labor saving will exceed the cost of the window.

When to have your aircraft windows serviced by the SARA™ System:

• At a predetermined Maintenance schedule
• During a scheduled interior or exterior paint and refurbishment
• During any major inspection or downtime
• When the operating environment has affected optical clarity
• When it is determined that SolGard™ coated windows require coating removal

Kit Surface Removal & Time on a Standard Commercial Window

• Light Refurbishment Kit

Up to .0005" (.0127mm)

8 Minutes

• Moderate Refurbishment Kit

Up to .0025" (.0635mm)

12 Minutes

• Heavy Refurbishment Kit

Up to .0035" (.0889mm)

15 Minutes
