Emergency Spindle Repair Service 

Our services include on-site spindle repairs as well as repairs performed in our facility. Whether you ship your spindle to us or have us come to you, we’ll get your spindle back on the floor as soon as possible!

Our emergency spindle repair service ensures that your spindle gets back on the floor as soon as possible. We have a staff of technicians ready to give you a quick turn around so that your machine spends a minimum amount of time off the floor. We can also come on-site and do most of our repairs at your facility. There might be a variety of reasons why you need to get your spindle repaired as soon as possible. Contact us today and we can work on a way to get you the results you need.

If you have an urgent need to get your spindle machine up and running, here’s what you can expect from our staff of technicians:

Step 1: Contacting Us

You can contact us anytime. We have someone (yes, a person) taking customer calls 24 hours a day, 7 days a week. Together we can determine whether shipping your spindle to us or having us come out to do the work on site is a better way of handling the repair.

Step 2: Receiving

When your spindle arrives at our facility, we log it in and create a work order. This way we can track its progress throughout the repair process. Then comes a visual inspection, as we look for any obvious signs of damage or other factors that often lead to spindle failure. Our trained technicians have been repairing spindles for years and know how to look for the most common indications of malfunction. We also do a preliminary vibration analysis so that we can make an initial diagnosis before disassembly.

Step 3: Disassembly

The inspection process continues as we disassemble the spindle, carefully looking for signs of contamination, lack of lubrication, support equipment failure, misuse, or anything unusual.

Step 4: Cleaning

Next, we start cleaning the disassembled parts and check for other signs of why the spindle failed or issues that could lead to premature failure.

Step 5: Inspection

We do a number of tests to see how the spindle compares to the OEM specs. We check the run out, alignment, optimal tolerance levels for housing bores, as well as shaft journals and parallelism. We want to get at the origin of the failure so that we can get it fixed right and give you guidance on how to circumvent future spindle issues. All of this information is written up in detail to help you take steps to avoid future spindle failures that can lead to down time and loss of productivity. Bearing contamination is a common cause for spindle failure. We inspect the bearings for preload, contamination, overloading, fretting, and overheating. We’ll make a recommendation for replacing your bearings so that you can extend spindle life and get better performance from it.

Step 6: Machining

If we need to manufacture new spindle components to replace one that is broken or damaged beyond repair, then we can do that in our on-site machine shop. Having in-house machining capability means we can manufacture replacement spindle parts without having to rely on the OEM. This saves valuable time and saves you money.

Step 7: Grinding

We also do our own in-house grinding and have a climate controlled area where we can grind to precision run outs. We hold tolerances of 0.0001” or better.

Step 8: Balancing

The next step is to get the balance right. We use our state-of-the-art balancing technology, developed by GTI Predictive Technology, to 2 stage balance all spindles that we rebuild. We will component balance and then perform final trim balance at maximum RPM to achieve the lowest unbalance and vibration levels possible.

Step 9: Reassembling

We put it all back together with new bearings, seals, o-rings, spacers, belleville washers, and any other reworked components. To prevent contamination, we do all of this in our clean room.

Step 10: Testing

Now that it’s put back together we test, test, test it. We test it for runout, temperature, and vibration. We do this work in increments, increasing RPM from 0 to the maximum RPM to ensure the spindle is properly broken in. We will then continue to test run at maximum RPM until we feel confident that your spindle is performing optimally—which is often better than when it was new. Final vibration test will read at .0395 over all velocity and the displacement specs will meet the recommended ISO grade scale.

Step 11: Final QC

Every spindle that we rebuild is then put through a redundant final QC process by an independent QC audit technician to ensure that all of our rebuild processes and specifications have been achieved or exceeded.

Step 12: Return Shipping

We paint and pack your newly repaired spindle in non-corrosive packing material and encase it in foam. It gets shipped to you either in a heavy-duty shipping box or, if it’s a large spindle, we custom build a wooden crate with custom support brackets to ensure its safe return to your facility. When you unpack your spindle you’ll not only be pleased with how it looks but you’ll be amazed at how well it performs.

Satisfaction Guaranteed

Your spindle will come with a complete service report with valuable information; including what repair services we performed and what parts we replaced. Also included is a complete vibration analysis report. We keep this information in our database for future reference.

Our emergency spindle repair service comes with a one-year warranty. This warranty starts from the day of installation on the machine, not the day of shipment like many of our competitors. Call us to arrange your repair and to get your spindle back into production. Toll free: 888-473-9675 GTI Spindle Technology
