“I had two spindles rebuilt by GTI and I dealt exclusively with Lisa. This was for a major aerospace manufacturer’s facility in Singapore. It was, as you would assume, a rush project and GTI responded accordingly. I had the spindle shipped to Singapore and the maintenance manager had his techs install it and my feedback a month or so later from him and the operator was it was the best spindle in their shop. I was in contact with Lisa and there was never any doubt as where they were in the process.” – Fred

“THANK YOU SO MUCH to everyone at GTI for expediting the assembly, testing, inspection and sign off of the spindle.
I just took receipt of it at 4:15 PM today and will coordinate with Eric to have it installed tomorrow. Please ensure that GTI issues the invoice to any of the three of us, so that we can receive and remit for payment right away.”

“I was assigned to the Grinding department to improve the efficiency and costs of our operation. Spindle repair was a large portion of our expenses in this area and we were currently sending spindles to all the major spindle rebuilders Setco, Northland tool, GSM, Precision Spindle to name a few.

After approaching all the major spindle rebuilders, with a need for a Spindle Management Program for our facility. We received three quoted proposals from American Precision, Southeast Setco, and GTI Spindle Technology. We interviewed with each of the companies and Thomas Hoenig from GTI Spindle Technology approached me with a spindle and machine maintenance proposal that not only incuded the service of rebuilding our spindles but covered all aspects of spindle and machine maintenance. I awarded GTI with our account.

I must honestly state that through the full support of cause of failure reports, quarterly vibration analysis, and machine diagnostics that are all part of this program we were able to reduce our spending of over $100,000 in spindle repair to $30,000 and on pace for an improvement the following year.

This program is a success due to the fact that we found that there are a lot of companies that can do a great job repairing spindles, but GTI’s program works towards the resolve of why the spindles are failing and cooperates in solving the root cause of those failures. I would encourage any company sending spindles for repair to try this program, it works.” – Michael, Technical Specialist

“Hi Mark,

I cannot tell you how much your phone call and this email means to me and our collaboration. This is exactly the feeling I walked away with when I left your shop earlier this year. I knew that I was dealing with a group of talented people that not only offered great products and services, but also had integrity and professionalism to stand behind their work and support me and my team along the way. There is nothing more to say other than thank you.

I will review the report and get back to you as soon as I can.

FYI, xxx here in xxx California would benefit tremendously from incorporating your predictive products into their processes, so standby for more information regarding my inquiry into their process and interest in pursuing predictive diagnostic tools.

Best regards – Gary – President & CEO”

“Everyone here is extremely happy with GTIs work last week. It’s nice to have a vendor-partner that you can count on to come through for you every time. And just so you know, I have been asked by many, many vendors to try their spindle services and turned down all of them. I also did something I never do which is offer my personal recommendation of your company to a gentleman that was calling on behalf of one of your competitors. I value my reputation and credibility too much to vouch for anyone else but I have made my first exception.

Please pass along my thanks to your folks in the states-especially Eric and the guys in Bloomington.”
