A new convincing concept!
- Highest precision for smallest turning parts
- Space-saving and compact design
- Optionally with opposed spindle
- Y-axis as standard
- Lowest setting-up times by external setting
- Driven tools with speed up to 18.000 rpm
- Spindle speed up to 15.000 rpm
Due to its construction, this turning center is perfectly suitable for highest precision machining of small to smallest component dimensions. The flexible modular system offers various machine variants in space saving design, all of which are characterised by a very small thermal growth.
This innovative tool concept is designed for highest precision, easiest handling, external measuring of tools and shortest set-up times. The tools are held in tool-blocks with 5 positions each. These tool-blocks can be installed and removed very fast via a specially developed interface and guarantee a repeatability of less than 0,01 mm. The new tools are installed and measured externally and the coolant supplies are adapted to the specific tool positions. Ideally this takes place during machining of the current job. Different turning spindles with concentricity and axial run-out < 0,5 µm are available.
All variants of the DOLittle series can be automated either by Benzinger own loading and unloading devices with shortest workpiece changing times or by separate robot cells. The use of a bar feeding system enables complete machining from the bar.
Modern control systems from Siemens and Fanuc with various programming options complete the overall package.
Version B1, B2, B3 and B5
Version - B1
Version - B2
Version - B3
The DOLittle B3 is equipped with a main and a counter spindle to enable complete machining of workpieces. Due to the design, the counter spindle can be moved in three directions (X / Y / Z) towards the main spindle for hand-over of the part. Accurate shape and position tolerances from the first to the second workpiece side can thus be maintained reliably. The innovative tool-blocks in combination with the Y-axis and the sixfold milling device with NC-swivel-axis enable the machining of complex and high-precision components.
