TNI - lathe

The machining of complex workpieces on the main and counter spindle is the focus of this CNC-turning machine. Starting with a variant with one turret for main and counter spindle machining expanding up to solutions with two turrets that can be used flexibly on the main and counter spindle, the TNI lathe series offers a wide range of diverse possibilities.

For example, a wide variety of turning spindles with spindle openings from 32 to 42 mm with radial and axial run-out down to < 0.7µm and speeds up to 8,000 rpm are available in conjunction with a wide variety of clamping systems for powerful but also sensitive clamping of the workpieces in the lathe.
Y-axes extend the application possibilities of the CNC-lathe in machining. Additionally, the set-up time for the tools is reduced. Furthermore, the fine adjustment of the tools to center height can be carried out via the NC axes of the machine tool itself.

All variants of the TNI lathe series can be automated either via Benzinger's own loading and unloading devices with the shortest possible workpiece change times or separate robot cells. The attachment of a bar feeder to the lathe also enables complete machining from the bar. State-of-the-art controls from Siemens and Fanuc with various programming options round off the overall package of this lathe.

TNI lathe - Version B2

The B2 lathe variant is equipped with a main and counter spindle and thus enables complete machining of the workpieces on the turning machine. Tool turrets with VDI 25 mounting with 12 (optionally 16) individually driven stations are used. The advantages of the Y-axis are also fully utilized here.

A high-precision version of the turret interface for the VDI 25 holders is available to optimize the setup time of the lathe. The reproducible repeat accuracy when inserting the tool holder is well below 0.01 mm. This means that tools in the holder can be measured externally and time-consuming readjustment in the CNC lathe is no longer necessary.

TNI lathe - Version B6

For simultaneous complete machining on the main and counter spindle, the lathe variant B6 is equipped with a second turret. Through the additional installation of a tailstock, longer parts can be additionally clamped between centers and still be completely machined on the main and counter spindle.

Tool turrets with VDI 25 mounting with 12 (optionally 16) individually driven stations are used. Both tool turrets can also be equipped with a Y-axis.

A high-precision design of the turret interface for the VDI 25 holders in the turning machine is available to optimize setup time. The reproducible repeat accuracy when inserting the tool holder is well below 0.01 mm. This means that tools in the holder can be measured externally and time-consuming readjustment in the CNC-lathe is no longer necessary.

TNI lathe - Version B10

Compared to the B6 turning machine series, the B10 lathe variant is equipped with an additional compound slide for the second turret. Each turret can be used on any turning spindle. This means, for example, that work can be carried out simultaneously on the main and counter spindles or simultaneously with two tools on one spindle. With the additional installation of a tailstock, longer parts can be additionally clamped between centers and still be completely machined simultaneously on the main and counter spindles.

The lathe uses tool turrets with VDI 25 mounting with 12 (optionally 16) individually driven stations. Both tool turrets can also be equipped with a Y-axis.
