Precision CNC Gang Tool Lathe
GTCNC Turning Centers provide superior mechanical advantages that equate tolonger life, better performance and highly accurate machining specifications.The ZV gang tool lathe is built with the most advanced machine constructiontechnology offered in the industry today with features and flexibility unmatchedin an affordable and sophisticated design.
With the mostadvanced CNC systems available in the industry, the ZV can be orderedin several model configurations based on the features and axes required.
This proposalis based on the 3 axis Model ZV with FullC axis, which incorporates the Fagor 8055iTB control.
Themodularity of the ZV allows it to beeasily adapted to a wide variety ofapplications. Packages have beendesigned to accommodate a range ofrequirements. We can offer live tooling, part catchers, sawing,automated loading systems, bar feed systems and an extensive array of toolingand workholding.
Machine Base
The machine is constructed from Meehanitecast iron, designed to provide a balance between rigidity and low inertial mass.In applications that require a small footprint, but need high rigidity this canbe critical.
The base does not compromise machiningquality, it is a balance between structural requirements for low vibration andminimum weight for rapid axis response. The key casting components are boltedin place and pinned after alignment to provide accuracy and repeatability inalignment.
Slide System
Rails
The slidedesign incorporates high performance “Super Rigidity” NSK linear rails mountedto sturdy, rigid, Meehanite castings on both axes. These NSK rails support 6circuit preloaded ball tracks. Each track is connected to the centralizedlubrication system.
Ballscrews
Precisionground class 3 double nut, pre-loaded NSK ball screws are located by pre-loadedangular contact NSK thrust bearing sets. Each ball nut and thrust bearing isconnected to the centralized lubrication system.
The X axisball screw is preloaded and mechanically balanced to prevent drop when power isturned off or the motor looses power.
Servo System
The X & Zaxis motors are driven through a 1:1ratio precision pulley system thus reducingthermal growth from the heatgenerated from motor.
The motorsare AC Digital High Response servos, This style is used due to its ability tosmoothly transition a change of direction. The Servo drives are linked to thecontroller with SERCOS fiber optical connections.
Each axis isequipped with independent home switches allowing easy re-homing on power up.These switches are backed by mechanical contact over-travel switches, these provide mechanical backup to theelectronic limits set within the control.
This systemprovides a generous machining envelope of 12” of travel in the
X-axisand 7.0” of travel in the Z-axis.
With itsvertical table equipped with 2 T-slots on the table, The ZV allows for the easymounting of a wide range of accessories.
The generous42mm (1.653”) center distance allows quick change riser systems to be used.
Spindle Systems
The ZVspindle is configured to ANSI A2-4 configuration . This can accept a 5C colletnose or a 5.3”(135mm) 3 jaw chuck.
Offering astandard 6,000 rpm spindle, the spindle employs four (4) P4 precision NSKbearings in a conventional spindle design.
This spindlecomes standard with an 8,000 rpm capable hydraulic collet closer creating a\"bar feed ready\" set up that is fully programmable.
Webelieve that a hydraulic collet closer offers better performance than “normal”air collet closers.
Internalrotating surfaces are lubricated with the hydraulic system oil, no dry airsurfaces exist in the closer. This leads to longer live and higher rpm limits.
Thissystem provide higher clamping loads thus eliminating push back of the bar inhigh load machining.
Hydraulicclamping of the chuck allows real world speeds and feeds when turning andfacing blanks.
The1.062” through hole allows the full capacity of a 5C collet to be used.
Vacuumclamping systems can be integrated through the draw tube.
Live Tooling
The ZV C axis model has full C axis capability.
Theoperations that can be completed are numerous:
v Cross drilling
v Off center drilling
v Slotting
v Sawing
v Face milling
v Helical milling
Each of theserequire a live spindle, there are numerous choices of spindle type and speed.
Turning Tooling
We have anextensive array of tool holders, work-holding devices, specialty tooling, andtooling packages and live tooling options available to satisfy most needs.
The ZV C axismodel comes with a set of standard 42mm center height holders.
These holderslocate in position using pins to provide repeatability.
Hardinge®style holders can be used on our optional riser system. Dynamic offers a complete tooling catalog withall tool holders as well as live tool holders.
