Rotary Rebuild

ITS Rotary Rebuild Services

Don't Replace Your Fadal Rotary Table - Simply Rebuild or Service it!

Two Basic Options:

1. Tune-Up - We service all Fadal rotary tables with a low cost "tune-up".
2. Rebuild It - With a complete rebuild for about 1/2 the replacement cost! 

The original Fadal rotary heads are still one of the best overall designed attachments for the Fadal machine. While there are many imported rotary heads that might "look good" on the outside, it's the inside that really counts. The simple fact is the Fadal rotary tables were specifically designed to take a crash and keep on working.
Once serviced, they will be good as new and ready for more years of dependable service.

We service all Rotary Tables and Heads attached to Fadal Machines:
Many different rotary heads were made throughout the years of production. A 4th or 5th rotary axis was one of the most popular machine options. In the early 90's we started shipping all machines "4th axis ready" which means the machine has all the wiring necessary. You basically only needed an amplifier and a axis controller card with software. Contact us if you thinking of adding a 4th axis, we offer all the necessary components.

Brief Rotary Table History

- A First Hand Account by David M. deCaussin Jr.-
The very first rotary table sold that was sold on the VMC45 in 1981. It was designed and manufactured by Fadal for the VMC45, it never realized full production after production the VMC45 was stopped.

Troyke Mfg. Co. - Afterwards, with the introduction of the VMC40 in 1984, we began offering the TROYKE rotary products as a 4th axis option. The table had an interesting full contact bearing surface using Turcite between the faceplate and the casting with radial bearings support for the faceplate spindle. Few of these units still remain in the field today. If needed, we can provide complete service for these units.

Soon after 1987, we started adapting many of the popular Japanese rotary tables. Some customers would send us their tables and we adapt our motors and 4th axis interface to them. Eventually we started adding the Tsudakoma, Tecnara and Nikken rotary tables as a direct option to all machines.

The Two Most Popular Rotary Tables:

VH65 - After years of installing and also repairing the many various manufactures rotary tables we sold, we learned what different designs worked and didn't work in the machines. The second rotary head Fadal designed was the VH65. The VH65 stands for Vertical or Horizontal mount and 6.5" diameter faceplate.
We incorporated all the best features of the Japanese designs. After that we created the TR65, the VH-5C and the V300.

TR65 - The TR65 (Tilt/Rotate, 6.5" dia. faceplate) had a unique clutch system build into the trunion for the B-axis. One of the biggest problems with 5-axis programming was that is was easier to crash than to program. And a B-axis crash usually resulted in the customer having to return the unit for repair. With this unique design, if the Z-axis crashed into the part, instead of damaging the gears it would simply slip the trunion clutch. The CNC knows the exact position of the B-axis because of the rotary scale feedback that is directly attached to the trunion and not the motor. The addition of the trunion clutch was so important because it virtually eliminated the disruption of operation for a service call.

As can you see, it's our knowledge and experience that best qualifies us to tune-up or completely rebuild your rotary table!

Here's a sample of what we typically get in to rebuild:

One can only wonder what's happened to some of the units we've rebuilt.

Common Failures:

A). Coolant contamination causes motor and rotary bearing failures, mostly to do with seals failing.
B). Ring and/or worm gear damage from excessive use and/or tools crashing into the rotary spindle.
C). Face plate spindle damage, we had one unit that actually collapsed part of the spindle shaft. Fortunately, we were able to repair the spindle, potentially saving the customer the cost of replacing the entire face plate spindle.

Here's a sample of what you get back:

Note: Did you know our lead Rotary Rebuild Engineer worked at FADAL for 18 years?

After we receive your Rotary we will tear down and perform an Initial Inspection of..

- Main Gear, Gear drive, Idler & Spindle
- Bearings, Seals & Covers
- Motors and Cables
- Scale Assembly

You will receive an estimate of repair 5-10 days (depending on workload) after receiving rotary unit. Repairs take an average of 10 to 30 working days after receiving approval. Evaluation charge of $500.00 will apply if you do not get it done.

Your rotary unit is repaired, reassembled and run in for 10 hours. It is then re-inspected, all final adjustments and calibrations are performed to the original manufactures specification. We warranty our complete Rebuilds for 1 year.

As you can see we are the most qualified to tune-up or rebuild your rotary table. Having been there from the beginning, we know exactly what your table needs to bring it up to original specifications. Simply call Toll Free 1-800-342-3475 for any questions.
