DOLittle - lathe


A new convincing concept!

  • Highest precision for smallest turning parts
  • Space-saving and compact design
  • Optionally with opposed spindle
  • Optionally with Y-axis
  • 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 design, this lathe is ideally suited for maximum precision with small to very small component dimensions. The flexible modular system offers a wide variety of machine variants in very compact installation space, all of which are characterized by an extremely low thermal cycle.

In addition to its precision, the innovative tool concept is designed for easy handling, external tool measurement, and the shortest possible set-up times. The turning machines are accommodated in tool blocks with five positions each. Via a specially developed interface, these blocks can be installed and removed within a few seconds, guaranteeing a changeover accuracy of < 0.01 mm. Outside the lathe, the new tools are inserted, measured and the coolant supply lines are adapted to the respective tool positions. Ideally, this is done while the CNC lathe is still processing the current job. A wide range of turning spindles with radial and axial run-out are available.

Down to < 0.5µm and speeds of up to 15,000 rpm are available in conjunction with a wide variety of clamping systems for sensitive clamping of the workpieces. Y-axes expand the machine's range of applications in machining and also reduce setup times due to the fact that tools can be calibrated via the NC axes of the lath itself. Up to six milling spindles in conjunction with an NC swivel axis enable a wide range of options for machining complex workpieces.

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

Innovatives Werkzeugkonzept

In addition to its precision, the innovative tool concept is designed for the simplest possible handling, external tool measurement, and the shortest possible set-up times. The CNC-turning machines are accommodated in tool blocks with five positions each. Via a specially developed interface, these blocks can be installed and removed within a few seconds, guaranteeing a changeover accuracy of < 0.01 mm within the turning machine. Outside the lathe, the new tools are inserted, measured and the coolant supply lines are adapted to the respective tool positions. Ideally, this is done while the lathe is still processing the current job.

Tool block DOLittle lathe for static tools:


  • Changeover time <10 seconds 

  • Setup and measurement of the tools outside the turning machine, thus parallel to the machining process

  • Changing accuracy < 0.01 mm

  • 4 receptacles each ø25 mm and 1 x 10mm (square)

  • In diameter 25, hydraulic expansion sleeves for tool shank ø12 mm, holders for ER16 and ER11 collets as well as high-frequency spindles can be clamped

  • Internal coolant supply for all tools, high coolant pressure possible for individual tools
