Productivity, precision, and stability
"For me, the most important requirement in this competitive field is the ability to deliver optimal productivity, precision, and stability,” according to Niru managing director Julien Ducommon, "and that's why I can say with certainty that my next CNC machine will also be a Bumotec."
Using a Bumotec s191V from Starrag, Niru Swiss cuts the 15-mm-high, 46-mm-wide case of the UR-111C wristwatch from Urwerk.
Mill/turn with Swiss precision
The Bumotec s191V mill/turn machine center combines Swiss mechanical functionality with state-of-the-art CNC control and drive technology, for precision, three- to five-axis cutting of complex components. Thanks to its stable mechanical concept and its linear drive technology, accuracies of just a few microns can be achieved. The thermal stabilization unit almost eliminates warm-up cycles when starting or after machining interruptions, according to the developer.
Un-filling the blank
The Urwerk wristwatch case is cut from an aluminum blank, including a 20-mm-deep side compartment to accommodate the movement.
With its UR-111C, Swiss watchmaker Urwerk has developed a mechanical wristwatch with a linear time display.
