• Use as a benchmark for future tests.
  Where applicable

Productivity is equipped to help you with all of your FANUC robot maintenance and service needs. A Productivity Preventive Maintenance program gives you peace of mind that your robot is operating in top condition. Productivity manages your tailored service plan so that you don’t have to ­— by providing dedicated personnel, easy scheduling and annual service reminders.

A Productivity robotic preventive maintenance is performed annually, or at 2000 robot hours, whichever comes first.

You can expect an expert technician to perform the following checks:

• Check the mechanical unit cables to make sure that they are free from severe kinks, that there are no cuts or tears in the wire insulation and that all terminations are secure.
• Tighten the external main mounting bolts.
  Clean all chips and debris from the mechanical unit.
• Check the mounting bolts/ screws on the end effector/ end of arm tool and tighten, if necessary.
• Check the robot connection cables to make sure that they are free from severe kinks, that there are no cuts or tears in the wire insulation and that all terminations are secure.
• Grease the balancer housing, if applicable for your robot.
• Inspect and where necessary clean the controller cabinet of dust and dirt.
• Replace the mechanical unit batteries – do NOT let them die. Failure to replace the batteries before they die may result in you having to re-master the robot.

Productivity Quality, Inc. will provide a half day of evaluations on your CNC machine tool.

• The telescoping ballbar from Renishaw, Inc. provides a simple, rapid check of your CNC machine tool’s positioning performance to recognized international standards (e.g. ISO, ASME etc) allowing you to benchmark and track the performance of your machines and to quickly diagnose problems.
• The Spindle Error Analyzer measures the motions of your machine tool spindle at operating speeds. It then analyzes and reports error motions that decrease part quality. These measurements aid in troubleshooting, prevent unnecessary spindle rebuilds, and result in increased part quality and decreased scrap.

Things you can do between Preventive Maintenance visits to help extend the life of your machine and keep it in smooth running condition:

• Perform a visual check of the entire machine.
• Get to know your machine by referring to the maintenance section of your operator’s manual.
• Check the hydraulic unit and lubrication tank daily to see that the pressure and fluid levels are correct.
• Check the air regulator and make sure the air pressure is correct and that there is no moisture in the lines.
• Clean chips out of the machine daily, and check for areas where chips may collect and compact.
• Check coolant daily and maintain the correct coolant level. Proper coolant mixture and cleanliness improve the machining operation; clean chips from the coolant tank regularly.
• Periodically check the hoses, belts, tool changer and way covers for signs of wear or malfunction.

By performing periodic maintenance procedures, you can identify potential failures before the result in unexpected downtime – maximizing your robot uptime. For specific details, refer to your robot’s mechanical and electrical manuals.

Daily Maintenance

Before daily operation (with robot OFF and NOT in motion):

• Check air pressure using gauges provided by your integrator.
• Clean all sensors and optics, and visually inspect components for damage.
• Check the mechanical unit for grease/oil leakage.
• Check the robot controller cooling fans.

While the robot is in operational mode:

• Check for unusual or strange sounds as it goes through its first cycle – this may indicate an internal problem. If that is the case, contact Productivity Service.
