Total Engineering Support!

Here's four key examples of the Total Support our customers receive:
Diagnoses - Direct help in determining if you really do need to replace the spindle. When working with engineers that design the machine, we can help determine if there's other elements in the spindle system that also need to be addressed before replacing a spindle.

Documentation - We provide very simple and concise, step by step instructions on how to install and get your replacement spindle in and running.  With our documentation we also include Preventative Maintenance tips to help avoid future failures and extend the life of your replacement spindle..
- Just like "the old days", we value our relationship with each and every customer.  We are driven by fairness and committed to your satisfaction. Click on the About Us page to learn about what guides us today.
Support - It's with our engineering knowledge that you are getting the absolute best product support possible at installation and beyond.
The spindle is one of the most important aspects of the machine.  Why buy a spindle from someone without the original engineering experience?


Types Spindles Rebuilt

  • Grease Pack- Standard lubrication for 7,500 - 10,000 rpm
  • Air/Oil - Used for both 10,000 and 15,000 rpm spindles. Oil is atomized with pressurized air and injected into the bearings. This provides maximum lubrication efficiency while reducing internal heat.  Although this system is the most effective, conversion from Grease Pack to Air/Oil is complicated and expensive.
  • Mist Lube - Original lubrication on earlier 10,000 and 15,000 spindles.  Same basic lubrication as Air/Oil but lacked monitoring systems.

About Air/Oil

We are the only company to specialize in the Air/Oil spindles.
Customers with this type of spindle should not allow themselves to be persuaded into switching over to a Grease Pack spindle, but should maintain their existing Air/Oil systems. In the Machine Tool Environment, the Air/Oil lubrication systems are much better than the grease lubricated spindles for several simple reasons:

  1. Air/Oil lubrication systems keep the spindle cartridge positively charged with an air/oil mixture which helps to prevent the machine tool coolants from penetrating the spindle cartridge.
  2. Also provides a constant cleaning action to the spindle bearings and races.
  3. In addition, it cools the ball bearings and races and help evacuate that heat from the spindle. Any heat in the spindle reduces its life. The cooler your spindle runs, the longer its going to last. Also, cooler spindle temperature provide for a more constant temperature range which directly translates to better depth control at the tool.

Not All Rebuilds Are The Same:


Over time and usage, the spindle taper tends to open up, this is known as "bell-mouthing" the taper. While some companies just regrind the taper without considering the spindle geometry, we carefully inspect the taper to ensure if correcting the taper will require too much material to be removed.  If this is the case we will Chrome plate the taper first then regrind the taper.  Doing this costs more but it guarantees that all spindles we ship have the correct wall thickness between the spindle taper and the spindle inter-bearing races (shown as Regrind Weakness in the above picture).  Too much taper grinding weakens the spindle shaft.
 Beware - We've even seen some spindle repairs just polish the taper with sand paper.  While it might seem cheaper and it might look good, but is it?
A quality spindle rebuild is more than replacing the bearings, proper tool support is the key to all machining.  The three conditions most important in controlling taper are: taper size, angle and straightness.
If the toolholder’s rate of taper is too great there will be excessive clearance between the tool holder and the spindle at the small end of the taper.
If the rate of taper is too small, there will be excessive clearance at the large end.
An error in straightness is known as a "barrel-shaped" error and is typically caused by bad tooling or hand polishing.  Either situation can reduce the rigidity of the connection and cause tool run-out and chatter, which may show up on the work piece as geometry and/or surface finish error.



Core Deposit Policy:

If we sold spindles without receiving a core return, we would need to sell the spindle for over $4500 and eventually only new spindles could be sold.  In order to provide the best quality and lowest cost spindle exchange, we offer a core credit for the return of your spindle.  It is our desire that you clearly understand how core returns are processed (as fairly as possible).  Basically, the value of core return is based upon us receiving a usable spindle i.e. a spindle that is repairable.   You will receive a refund check for $800 if we receive a spindle that simply needs cleaning, inspection, simple repairs, new bearings and a minor grind on the taper.. Which is the case most of the time, however when we do receive a damaged spindle core that needs repair, the extra repair charges are deducted from the deposit. The $800 deposit then is reduce by our cost to repair/replace the damaged or missing parts. We will not deduct for minor repairs only for major damage.  For example, below are most of the worst case core repair adjustments:

  • Broken or Missing Drawbar: May reduce the refund by $500.
  • Spindle Taper damage: If grinding the taper requires too much material to be removed, we must Chrome plate the taper first then regrind the taper.  Doing this costs $500 but guarantees that all spindles we ship have the correct wall thickness between the spindle taper and the spindle inter-bearing races, see above.
  • Damaged Key Way: When the key ways are broken or severely damaged from crashes, we are required to repair or replace the spindle shaft.   The cost depends on the severity of the damage.  The worst case is to replace the entire spindle shaft for $690.
  • Bearing Seize: The spindle shaft bearing journal can be damaged when a bearing seizes. The worst case is to replace the entire spindle shaft for $690.

The total deduction will not exceed the core deposit.  If requested, we will return the spindle core to you (unassembled).  It is our goal that you understand our core return policy and that we strive to come up with a core exchange program that is as fair as possible.
Your satisfaction is important to us and we will gladly explain any core refund reductions.
