In this photo the Matsuura Spindle we received for repair had a bent shaft. The shaft was bent do to the machine actuating and applying too much torque on the shaft which potentially caused the spindle to bend. In this spindle repair process Andy is replacing the bent shaft with a new one to ensure the spindle runs correctly. Visit Our Matsuura Page Here
Matsuura MAM700 Spindle Repair
A spindle failing during a customer’s busy time is not good thing. Our customer called and needed this spindle repair done as soon as possible. We received the spindle and found that the shaft nose OD rubbed out on the front cover. The shaft taper had 18 microns of run out and the front bearings were contaminated. The spindle would need grind, chrome plate and finish grind to the taper, a kiss grind to the OD nose and front cover. We expedited the shaft rework through our Kellenberger grinding department. The shaft was then hand carried to the platers and picked up the following day. The shaft was put on the Kellenberger grinder the same day that it was picked up. Our spindle repair technician replaced the drawbar, springs, grippers, bearings and orings. The taper now has only 1 micron of run out. All out going test show that the spindle had good balance and drawbar force. The customer received their spindle repair back within 4 days.
Matsuura R plus 800 Spindle Repair
The rear roller bearing failed in this spindle. The tooling taper had 9 microns of run out and needed to be reworked.
This machine was an intricate part of our customers production process and they could not have the machine down for to long. We worked with them to make sure we had the bearings needed for the repair in stock when the spindle arrived. We were able to rework the taper in our grinding department the day the spindle was approved. In fact the spindle was in our clean room being assembled before the end of the approval day. The next day the repair was completed, test run and passed our strict final QC by noon. The spindle shipped that day and our customer was up and running within two days of removing the spindle.
Matsuura RA3 Spindle Repair
This spindle had oil contamination in the front bearings causing them to overheat and fail. The taper was also worn and had run out. Our customer requested a rush repair as this machine was intricate to his production. We were able to kiss grind the 40 taper on our Kellenburger ID/OD grinder and assemble the spindle with bearings taken from our stock. Having our own grinding department on site makes fast turn repairs like this possible.
Before using Northland Tool & Electronics our customer was using the OEM for his spindle repairs. This was a costly route to go for two reasons. The first being the inflated cost of the repair itself, the second being the OEM insisted our customer pay to have them install the spindles. Our customer has the knowledge, ability and staff to maintain their machines and was tired of being forced to pay far to much to the OEM. We discussed our repair programs with them and determined we would be a good option to replace the OEM. Our one year warranty covers our repair regardless of who installs the spindle.

Matsuura HPLUS 300
Matsuura ES450H with BIG PLUS
This customer runs their Matsuura ES450H spindles at maximum rpm with the maximum feed rates possible. They know that this will reduce the spindle life but when taking the increased part output into consideration the process was deemed cost effective. As the repair costs from the OEM increased the profitability was questioned. When Northland Tool made our proposal we were able to reduce their repair costs per spindle by 50%. Our customer has also informed us that the Northland Tool repairs are lasting at least 50% longer than the OEM repairs. The customer is also saving on removal and installation costs as Northland Tool allows them to perform the removal and installation themselves and still provides a 1 year warranty. The machine distributor mandates they pay them to remove and install all the spindles or they will not provide a warranty. Visit Our Matsuura Page Here
