We service all Rotary Tables and Heads attached to Fadal Machines:
Many different rotary heads were sold with Fadal machines 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. Simply call Toll Free 1-888-727-1887 for any questions you might have.
Brief Rotary Table History:
The very first rotary table sold that was sold on
the Fadal VMC45 in 1981. It was designed and manufactured by
Fadal for the VMC45, more of a prototype, never realized full
production after the VMC45.
Troyke Mfg. Co.
Afterwards, with the introduction of the VMC40 in 1984, we began
offering the TROYKE rotary products as 4th axis option. The
table used an interesting full contact bearing surface using Turcite
between the faceplate and the casting with radial bearing for support
for the faceplate spindle. Very few of theses units remain in
the field today. If needed, we can provide 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 Fadal Rotary
Tables:
VH65
- After years of installing and also repairing the many various
manufactures rotary tables we sold, we saw 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. 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.
As can you see, its our knowledge and experience that best qualifies us
to repair or completely rebuild your rotary tables!
Here's a sample of what we typically get
in to
repair:


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 reinspected, 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.
