Our MICROTURN-L is an ultra precision fine turning machine in a unique design to produce workpieces at the highest level.

The highly precise motorised spindle moving on an X/Z axis is the heart of the repeatability to achieve the highest accuracies.

In front of the spindle is a linear tool carrier for holding fixed precision turning tools for fine turning. In addition to turning tools, other units such as grinding spindles, deep-hole drilling devices or grippers can also be mounted on this for integrated automation.

All linear and rotary axes have direct measuring systems.

The MICROTURN is a unique concept on the market in this precision, MADE IN GERMANY in our main factory in Sauerlach near Munich.

Our MICROTURN-LT as a turning-milling centre is the combination of an ultra precision fine turning machine and a universal lathe in a unique design to produce workpieces at the highest level. The high-precision motorised spindle moving on an X/Z axis is the heart of the repeatability to achieve the highest accuracies.

Opposite the spindle are two different tool carriers:

  • The linear tool carrier for holding fixed precision turning tools for ultra-fine turning.
  • The turret with Y-axis at the bottom of the work area for more universal cutting operations

All linear and rotary axes have direct measuring systems.

The MICROTURN is a unique concept on the market in accuracy and complexity, MADE IN GERMANY in our main factory near Munich.

Our MICROTURN-LTB as a turning-milling centre is the combination of an ultra-precision fine turning machine with a 5-axis machining centre in a unique design to produce workpieces at the highest level in only one clamping.
The high-precision motorised spindles moving on an X/Z axis are the heart of the repeatability to achieve the highest accuracies.
Between the two spindles are three different tool carriers:

  • The linear tool carrier for holding fixed precision turning tools for ultra-fine turning.
  • The turret with Y-axis at the bottom of the work area for more universal cutting operations
  • The milling spindle with Y- and B-axis at the top of the workspace for turning/milling applications with up to 72 tools

All linear and rotary axes have direct measuring systems.

Our MICROTURN-LTBS Ultra-Precision Turn-Mill-Center is a combination between a submicron precsion lathe and a 5-axis Machining Center in unique design to produce highest level of workpieces in one operation only. The two oposite identical turning spindles moving in X/Z-axis are the heard of the precision repeatability for reaching closest tolerances. In between the two spindles are three toolholding devices such as

  • Gang-type fixed table to wear fixed precision turning tools for submicron turning
  • Turret with Y-axis in the bottom of working area for universal apllications
  • Milling spindle with toolchanger, B-axis and Y-axis in upper working area for Turn-Mill applications with up to 72 tools

All linear and rotative axis with linear scales.

There is no machine of similar precison and complexity on the market. Made in Germany in our Sauerlach-Munich Factory.

Our MICROTURN-GRIND is the first true combination of an ultraprecision hard turning machine and an internal and external grinding machine. With the MICROTURN-GRIND, you can not only fine-turn your workpieces with high precision in the hard condition (heat-treated), but also grind them using a 400 mm external grinding wheel and up to two high-performance internal grinding spindles. By using such a machine, you minimise stock oversizes required for grinding, reduce cycle times and optimise accuracies.

Hard machining of threads, recesses and contours is also possible thanks to the machine's full turning functionality with up to 10,000 rpm on the workpiece spindle or grinding of non-circular polygon shapes thanks to high-precision C-axis interpolation of the workpiece at creep speed.

The indexing turret mounted at the bottom of the work area allows high-precision soft and hard turning of internal and external contours on both spindle 1 and spindle 2. Milling operations with live tools and Y-axis are also possible, e.g. for soft and hard milling of surfaces, keyways and other contour elements - all during the same operation.
