SPS Spindle Gallery
-
- This large surface grinding spindle from a Faveretto machine just went through a comprehensive disassembly and inspection at SPS Spindle. A detailed quote, including a cause of failure analysis, will be sent to the customer to guide the next steps.
-
- Pictured here is a Renaud spindle from a Rollomatic tool grinding machine. The spindle was experiencing issues with overheating and difficulty holding size—challenges that required expert attention. After a detailed evaluation, SPS Spindle developed a solid solution to address the problem. Once we shared our plan and discussed it with the customer, they gave us the green light to put our idea into motion.
-
- SPS finished up repairs on a Mazak lathe head. Used in industries ranging from aerospace to medical and consumer electronics to construction, Mazak provides a wide range of machining solutions. Once packaged up, it was shipped back to the customer with our one-year warranty.
-
- SPS recently completed repairs on a Mori Seiki spindle bearing. While we take care of the repairs on the front housing and shaft, the stator and rear bearing stays with the machine.
-
- A Kessler spindle with an HSK-100 taper getting set up for a test run. SPS tests all spindles that come in for repairs, even a large 40 kva spindle like this one with a Siemens stator.
-
- A tool changer arm was recently brought in for repair. Our technicians thoroughly inspect all spindles and tools, and a quote is provided to customers prior to the work on repairs beginning.
-
- A Fortune 5 axis head was recently in the shop for repairs. Fortune is a manufacturer of heavy-duty CNC machine tools, CNC lathes, injection molding machines, finger chucks, and vertical and horizontal machining centers. SPS can handle the repairs on products from most spindle and machine tool manufacturers.
-
- SPS uses various styles of seals when rebuilding spindles. Lip seals are used on slow-turning spindles because they make shaft contact and generate heat. When spindle speeds increase, we go with the brass non-contact seals to keep debris out of the bearings. Some seals, like those made by Garlock, replace the whole front cover of the spindle. Using quality spindle seals, some of our customers have seen up to a 60% reduction in spindle failures.
-
- This repair required testing the stator on a Meger. This equipment delivers current into the stator to see if there are any shorts in the winding, and as you can see, this one did pass. SPS tests all electrical stators and encoders during the breakdown and quoting process.
-
- This Okamoto ID Grinder work head spindle was recently in the shop for repair. SPS also supplied the customer with a new belt. Whether you are running multiple high-speed machining centers with the latest in spindle monitoring technology or a single surface grinder, SPS has trained spindle repair technicians and support staff to provide quality spindle rebuilding services quickly to keep up with production demands.
-
- This fifty taper Awea milling spindle recently arrived at SPS for repair. The customer found that the hydraulic actuator was leaking. The result was an excessive amount of oil was in the gear area, which also leaked into the grease pack spindle bearings, washing the grease out. SPS rebuilt the actuator and test it for and leakage.
-
- One of SPS Spindle’s customers crashed his spindle so hard it bent the shaft. With the shaft having internal threads, it was necessary to manufacture a new shaft for his spindle.
-
- This is the inside of a Mazak Turning center spindle. This spindle failed due to the coolant being blasted down the shaft and leaking into the back of the machine, which contaminated the rear roller bearing.
-
- One SPS technician had to dial in the drawbar pressure on a Daiwoo spindle. All drawbar Belleville washers are replaced and tested before being returned to the customer.
-
- This Haas spindle is on the test stand being trim balanced with our Balmac balancer. Being able to balance the spindle while it is fully assembled, with new bearings, is optimum to ensure the spindle will run perfectly in the machine when the customer installs it.
-
- This new Capellini rotary dressing spindle is heading out to our customer CNC North. They will be installing it on a newly rebuilt machine.
-
- This spindle just came in for repair. It’s a large 50-taper Mazak HCN-6000 motorized spindle. Like all the others we repair, this spindle will be thoroughly tested at full speed. This spindle will be run on one of our many different drives, with coolant and the proper oil injection rates.
-
- This is a DMG/MORI SH-4000 spindle that came in for repair. This model spindle only comes with the front bearing housing and the rear bearing sleeve. Our customer will need to install the rebuilt spindle and retest it at their facility before releasing it to production. Many of the modern Japanese spindles are done this way. It helps make the spindle change-out process more efficient and faster.
-
- A Bryant LF Grinding head is waiting to be hand carried to our local customer. Whenever possible, SPS will deliver and pick up all of our local customers’ spindles. You can see that our spindles are always shipped with quality control documents.

-
- This Kitamuura 50 taper milling spindle arrived after the customer’s gearbox seized up, destroying the gears. The spindle was pulled out, and we did a test run with two new drive gears supplied by the customer to see if it was bad as well. The spindle, which was full of dirty oil, did not perform well, and we recommended that it be rebuilt.
-
- We recently worked on two styles of Haas spindles simultaneously. The one in the foreground is out of a Mini Mill, and the black one is a direct drive via coupling spindle that came out of a VF 2.

One larger spindle has the grinding wheel on it and a smaller regulating spindle with a rubber-based wheel on it that maintains the speed of the part, so it is ground correctly. A lot of centerless grinders are set up with a through feed grind cycle and may have multiple grit wheels to rough and finish grind in the same through pass.
