With the ability to integrate a grinding and milling spindle, it becomes possible to build a high-performance machining center out a grinding machine. With the spindle power up to 45 kW and 345 Nm can be obtained at 6000 rpm. RAM cross section of 250x250mm, tool holders CAPTO / HSK / KM / Berthiez tool holder for turning tools and CAPTO / HSK / KM / ISO for milling tools.
Berthiez TVU 2800/250
Increased productivity through complete machining thanks to integrated grinding and milling spindle / high-pressure coolant pack
A wide range of peripherals enables a high degree of automation.
A solid cast iron construction with excellent vibration damping ensures reliability and is the basis for highest accuracy and excellent surface qualities.
vertical turning lathe
The vertical lathes of the TVU product line of Berthiez are especially suited for machining engine and turbine components, which are primarily used in the aerospace industry as well as for alternative and classical power generation. The TVU vertical lathes are characterized by a complete cast design, high-precision static and dynamic positioning as well as long-lasting reliability.
Advantages of the TVU vertical turning lathes are, completely cast iron construction, high static and dynamic axis stability, high accuracies and long term reliability. For higher flexibility the machine can be equipped with several pallet change systems and adaptable milling heads. The optional Y-axis table traverse will permit the turning, milling and grinding of complex components in a single clamping.
Axis configuration
Innovative Solutions
Using high pressure coolant can result in significant increases in productivity in the processing of difficult machine materials such as Titanium can be obtained. Berthiez offers solutions up to 400 bar.
The pallet changing systems range from palletizing RTS of a double changer through to multi-pallet system with manual or automatic clamping.
With the new optional Y-axis in the table is it possible to edit the workpiece at each position. The axis has a travel range of +200 /-400mm.
The user has a variety of solutions to choose magazine. The disc-type magazine can manage up to 50 seats, the chain magazine allows up to 120 seats and to the tool change robot has a capacity of up to 250 seats.
The cast iron construction allows excellent vibration damping and high stiffness. It forms the basis for high accuracy and excellent surface quality.
In the TVU series provides users with a extensive range of accessories available. Angle milling, swivel heads with manual or automatic adjustment, grinding spindles, hydraulic chuck with 3,4,6 jaws.
