Construction
| Rotary Toolholders
consist of: |
| 1. |
Outer Shell -
Hardened steel, O.D. precision ground to size and tolerance shown. Non-rotating in use. |
| 2. |
Rotating Shaft -
Hardened steel, precision ground to size and tolerance shown. Toolholders are provided
with four standard types of tool sockets from which to choose. (additional socket and
shank combinations are available) |
| 3. |
Bearings - Caged
needles provide anti-friction rotation and radial load support. |
| 4. |
Seals - Seal and
rear flinger extend the life of the Rotary Toolholder. |
| 5. |
Lubrication -
Lubricated with light duty general purpose grease. Lube hole provided for maintenance
lubrication. |
Note: Woodruff key, stop
nut and drawbar are not included.

Operation
In operation, a Gatco Anti-Friction Rotary
Toolholder is guided by a support sleeve as it travels toward the workpiece. The
recommended close tolerance fit (.0003 to .0005 clearance) of the shell to the support
sleeve restricts the shell from rotating. The Toolholder shaft rotates friction free
within the needle bearings providing an accurate, chatter free operation.
In addition, the anti-friction rotation all but eliminates
heat build-up and thermal expansion, greatly increasing the life of the Toolholder, the
support sleeve and the tooling. Also, higher operating speeds can be achieved. This
ultimately results in a lower cost per piece machined.
Special Designs And Features
Special Toolholders and modified standards can be designed
for specific applications. Rotary Toolholders can be furnished with tapered shanks,
special O.D.'s, special lengths, etc.. In an effort to provide the metal cutting industry
with a wide selection of Rotary Toolholders, Gatco, Inc. also offers Rotary Toolholders in
metric sizes, Coolant Induced Rotary Toolholders, Indexable Rotary Toolholders and
Floating Rotary Toolholders.
Standard Gatco Rotary Toolholders are commonly modified for
particular applications. If a standard or modified standard will not meet your
requirements contact Gatco for a search of over 3000 special designs.
Gatco offers a special
design service for rotary toolholders. Your special design requirements will
be taken from design concept through final manufacture. Our engineering department can
make recommendations which will make your machine run at maximum optimization. Because of
our CAD capability, if we are furnished with size and performance requirements, a special
design can usually be prepared for customer's approval within hours. When requesting a
special design, please provide prints and all pertinent information regarding the
operation. Availability for specials and standards is the same; pricing covers the
additional features ordered.
