FANUC ROBODRILL SPINDLE REPAIR
With over 40 years of spindle rebuilding experience, the team at Northland Tool & Electronics can rebuild a wide range of spindles with the precision required to do the job right.
Fanuc Robodrill is one of the brands we see most frequently here at Northland Tool. In some cases, our customers require their Fanuc Robodrill to perform beyond its standard operating capabilities. We are able to make customizations on most spindles to optimize performance, and we are frequently asked to modify the bearing complement on Fanuc Robodrill models to better suit the process. Doing so will lead to longer bearing life and an overall more reliable repair.
In addition to repairs and customizations, we are able to finish balance with the balance ring and drawbar, which ensures a better part finish and longer spindle life. We have seen instances where the Robodrill is installed and balanced on the machine, which can cause premature failure and other issues.
Common Fanuc Robodrill Issues
From coolant contamination to bearing failure to crashes, Northland knows that there are a variety of issues that can affect the performance of your spindle, and we’re prepared to handle them all. Some common issues that Fanuc Robodrill spindles encounter include:
- Bad O-rings

- Our technicians carefully break down the spindle into its component parts, note their general condition as well as specific damage and perform a full dimensional inspection to identify excessive wear.
- Our production manager performs a second evaluation, during which he/she will identify the mode of failure, consult with the head of our grinding and machining department and determine recommendations for future preventative measures.
- Our purchasing department sources all replacement part costs, determines lead times and generates a quote.
- Our team gives the quote a final check and communicates it to the customer for approval.
- Following customer approval, we schedule production and order the parts needed.
- Once we receive the parts, we carefully clean them and complete any necessary grinding or machining operations.
- Our highly trained technicians assemble all spindle components and perform a rigorous break-in process. This may include dynamic balancing and thermal and vibration analysis.
- After our inspectors perform a final quality control check, our shipping department carefully boxes the spindle and returns it to the customer.
