A 10-step process is used for failure analysis and best solution determination. It begins with
the creation of a database for your equipment. This will be used to track and document your
spindle throughout the remanufacturing process.

Thorough bench testing of spindles and motors includes extensive vibration diagnostics and
spindle temperature analysis. Runout readings will be taken on all exterior surfaces with
precision test equipment. Each integral part of the spindle or motor will be meticulously
cleaned and analyzed for any deviation from our lab tolerances and specifications. Optimal
tolerance levels for housing bores and shaft bearings will be determined.

After complete spindle analysis, you will be notified about our recommendations for spindle
repair or upgrade.  Then after your approval the process will continue.  Only when all optimal
tolerances are achieved, your equipment will be reassembled in a temperature-controlled clean
room.

Final balancing, performance testing and inspection will conclude the process, and all
documentation will be included in your database files.


Step 1:     -Spindle is received
-All paperwork is logged into our system
-Digital photographs are taken of the spindle before disassembly

If the until can be test run without harming the spindle any further it will go directly onto one
of our test benches for vibration readings.  Should the spindle prove to be within OEM specs
the customer will be notified & no repair will be conducted.  

Step 2:  -  Tear Down
Step 3:  -  Inspection of All components
Step 4:  -  Detailed write up & Quotation
Step 5:  -  AFTER approval the repair process begins
Step 6:  -  Requalify all components as necessary
Step 7:  -  Dynamic Balance
Step 8:  -  Assemble (New Precisoin Brgs, Seals, & Etc. as required)
Step 9:  -  Test Run (Run up to Max RPM, Leak Test, Drawbar Test)
Step 10:  -  Final Inspection
