GTV Turning Center: Speed That’s out of This
World!
Now Available with 16C Collet (42mm bar capacity)
GTV is now available with both 27mm and 42mm
spindle capacity. In terms of collet sizes, this means customers can choose
either 5C or 16C type spindle collet configuration depending on their required
part diameter. The larger spindle capacity comes without any sacrifice to the
high speed machining capability that GTV is known for.
As always, hydraulic 3-jaw chucks are also available as workholding options.
High Accuracy
The most significant feature of the GTV is the
ultra accuracy that it can maintain. No other competing gang tool turning center
can match with the resolution of the GTV. 0.00005” (
50 millionths) positioning accuracy is standard. We use preloaded double-nut NSK
ballscrew in X & Z axes. The ballscrews are supported with NSK
angular contact P4-class bearings and matched to NSK LA-series
Super Rigid linear rails. When accuracy counts and you need dependability, turn
to GTV.
Superior Speed & Acceleration
The GTV provides the fastest response in the gang
tool market. Powered by an oversized, 7.3 HP spindle motor, whether its a simple
2 axis component or a complex 3 axis part the GTV will
produce the fastest cycle time. PERIOD.
Vertical Design
The vertical tool slide design offers numerous machining benefits. Chip flow
is the most obvious. This allows tools to be free of chips and allows for
faster, more efficient part production. The tool slide also features
on-the-table coolant for precise coolant delivery. In addition, the vertical
design simplifies the use of live tooling making the spindle positioning and
contouring options even easier to work with. The vertical design allows easy
access to see the tools when setting up. With 42mm center height, no longer are
centerline confinements of live tool size an issue. Finally, the vertical design
allows dramatic space saving. It is very ergonomic and allows operators easy
access for setups and part handling.
Got Gang Tools?
Gang tooled machines are more accurate. Period! Featuring all NSK
components: ballscrews, linear ways, and spindle bearings, the GTV
provides a level of accuracy above the crowd. These components are chosen to
maximize speed. Up to 1181”/min rapids, get you into the cut faster, reducing
cycle times and saving you money. Multiple tool choices, including creative live
tool options, help you compete in a competitive market.
FANUC or FAGOR Controls
We use world leading controls and servo systems from FANUC
& FAGOR. The GTV can be
equipped with either control system! And either in 2- or 3- axis configuration.
Each configuration is matched — servos, drives and controllers are from the
same manufacturer. Choose FANUC or FAGOR
and count on their reputation. Using either control gives you instant
productivity, and instant profitability.
Tooling Options
Many tooling and workholding configurations are available.
- Quick changeover systems
- 5C or Dead length
- Adjustable height holders for stick tooling
- Live tooling holders for all applications
- Air or electric live tool spindles
