Don't Replace Your Fadal Rotary Table - Simply 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.
As you'll see below, we are the most qualified to repair your rotary table. Having been there from the beginning, we know exactly what your table needs to bring it up to original specifications.

Brief Rotary Table History - A First
Hand Account:
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 theses 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, its our knowledge and experience that best qualifies us
to tune-up or completely rebuild your rotary tables!
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:
- Coolant contamination causes motor and rotary bearing
failures, mostly to do with seals failing.
- Ring and/or worm gear damage from excessive use and/or tools crashing
into the rotary spindle.
- Face plate spindle damage, we had one
unit that actually collapsed part of the spindle shaft. With
that unit we were able to repair the spindle, saving the customer
the cost of replacing the entire face plate spindle.
Here's a sample of what you get back:
Initial Inspection upon receipt of rotary unit:
- Main gear
and worm gear
- Bearings and Seals
- Motor and Cable
You will receive an estimate of repair 2 days after receiving rotary
unit.
Repairs take
an average of 5 working days after receiving approval.
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 one year and we warranty our
Repairs for 6 months.
