Our process…precision

Vibration Analysis

This essential first step determines the most common malfunctions – or lack thereof – quickly. It’s not uncommon for us to receive a perfectly functioning spindle that was just pulled prematurely from its machine. Through computerized, state of the art vibration analytics we can help you arrive at a solution to those problems that originated on your machine floor.

Spindle Disassembly, Cleaning and Inspection

Your spindle is disassembled and thoroughly cleaned. While broken down, the spindle’s every component is inspected for issues like; misalignment, lack of preload-to-bearings, crash damage, contamination and other typical causes of failure. Our technicians are trained to recognize signs of dysfunction on almost every spindle and bearing manufactured worldwide.

Failure Analysis and Hard Repair Quote

Once the cause of failure is diagnosed we give our repair recommendations containing a detailed scope of the work and a hard price guarantee, something that truly sets us apart from the competition. We do this expeditiously, as customers often put another spindle into use too soon, unaware if our diagnostics found issues entirely unrelated to the spindle – like operator or machine error – to be the cause of the breakdown. We don’t want you compromising a second spindle!

“I just wanted to take a moment to let you know that we are impressed thus far with the performance and services that GTI provides. The attention to detail has been a breath of fresh air.” — Customer in New York.

Balancing, Fine Tuning, Reassembly

Before reassembly, every spindle is fine-tuned and balanced to higher-than OEM specifications. OEM’s balance standards are typically .05 inches per second, while we always balance to below .04 IPS, and typically ship spindles under .03, providing smoother operation, longer operational life and better performance.

Our reassembly includes the grinding and machining of all repaired parts. Where damage was too extensive, all new parts are manufactured at our on-site machine shop. Having this capability means we don’t have to rely on OEM, saving us time and saving you money.

Final Quality Control Audit and Return

The repair process comes to a conclusion with a thorough, independent quality control audit from a separate technician who again checks the spindle’s every element. Your spindle is painted and packed in non-corrosive packing material and encased in foam. You’ll be amazed at both how it looks and performs.

Our spindle repair covers all major brands and a wide variety of spindle models, both foreign and domestic.


For your convenience we staff on-call customer service representatives 24 hours a day. And while the standard turnaround time for regular repairs is 10-20 business days, we know some jobs are just too important. For an additional charge, we offer a premium QTA (quick-time turnaround) of two-to-five business days.


We offer a one-year warranty on all repairs. This guarantee starts on the date the spindle is installed back on your machine, not the day of shipment – even if that re-installation occurs months later. Our warranty is yet another courtesy our competitors can’t match.
