MICROTURN GRIND - Hard turning & grinding simultaneously on one machine
Ultraprecision Turning
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 400mm (15.74") external grinding wheel and up to two high-performance internal grinding spindles. By using such a machine, you minimize stock oversize required for grinding, reduce cycle times, and optimize 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 one and spindle two. 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.
