The new MAXXTURN 65 G2 has undergone an extensive redesign and, in addition to two powerful motor spindles, now also offers an optional BMT turret with direct drive. For the first time, three spindle sizes can be offered. A steady rest is available for shaft machining if required. While the proven two-part basic design has been retained, the integration of the chip conveyor has been optimized.
The generously dimensioned work area provides space for a large number of tools on the tool turret and, with an angle of inclination of 40°, ensures continuous chip flow even during low-manpower operations. An optional drag steady rest enables precise and safe machining of long shaft components. When not in use, it can be removed quickly and easily. The work area is optimally accessible, which also facilitates the setup for small batch sizes.
There are three spindle sizes to choose from. One is the 65 spindle with A2-6 and for larger bar parts once the 76 and the 95 spindle with A2-8. For complex milling operations, the spindle can be moved interpolating. The direct drive ensures extremely precise and dynamic positioning.
The counter spindle is available for complete workpiece machining. Turning, milling and drilling operations can thus also be performed on the back of the workpieces. The concentric takeover of the workpieces offers another advantage: the possibility to maintain a very high level of accuracy with regard to the coaxiality, concentricity and angular position values.
Fast 12-fold servo turret with very short switching times for VDI 30 or VDI 40 tools. The angle holders are equipped with ground alignment plates. This eliminates the need for time-consuming alignment of the tool holders. All stations are driven and the swivel speed is adjustable.
For the economical production of complex turning/milling work- pieces with a predominantly milling component, a 12- or 16-position BMT turret with direct drive is available as an option. With up to 12000 rpm, this turret offers optimum conditions for complete machining. The stable BMT interface allows coolant pressures of up to 50 bar as standard and up to 150 bar as an option. Further advan- tages are the changeover accuracy and stability of the interface.
The hydraulically operated steady rest with a centring range of ø 8 – 101 mm sits on a sliding carriage which is dragged and positioned over the tool slide. It is hydraulically clamped into position by a clamping device. Equipped with chip protection and end position control, the steady rest is connected to the central lubrication system.
In order to support slim components, the MAXXTURN 65 G2 includes a fully automatic tailstock. It is hydraulically moved over a length of 500 mm. The centre with MT4 cone is directly included in the tailstock body. This ensures compactness and highest stability.
The 90° offset machine base with the broad-based, pre-stressed guide rails ensures short overhangs and top stability for complete machining.
