What makes Roeders unique
Take a look at 200 years of company history and successful innovation, what Roeders does differently and why Roeders is particularly efficient in service.
Frequently asked questions about precision down to the submicron range
Submicron precision — accuracies below one micrometer — depends on the machine, its control and the machining process working together. The answers below explain why Roeders achieves the highest precision in milling and grinding, down to the submicron range.
Accuracies below one micrometer (0.001 mm) on the finished part — in geometry and surface finish. Achieving it reliably requires the machine, control and process working together, not just one precise component.
Thermal stability, high structural stiffness with low-friction guideways, high-resolution measuring systems, and a control/drive system fast and precisely enough regulated to follow the tool path without deviation. Roeders develops the control, drives and mechanics in-house, so these elements are perfectly tuned to one another.
The control interpolates the programmed tool path and determines the feed rate. This decides how accurately the machine follows the programmed tool path. The Roeders RMS6 control and drives process NC blocks in less than 0.1 ms with a look-ahead of more than 10,000 blocks and 32 kHz clock frequency in the drive modules, so contours are machined precisely even at high feed rates.
Thermal drift is one of the biggest enemies of submicron accuracy. Roeders overcomes it with the long-time developed PRECITEMP® technology and thermally stable machine design, achieving high accuracies even when the ambient temperature at the installation site is not constant.
Low-friction, highly precise guideways with NANOTOL® concept avoid the micro-movements typical for roller guideways, while high-resolution optical scales resolve the axis positions within nanometer range — the basis for repeatable submicron results.
The process matters as much as the machine — cutting strategy, tooling and CAM programming are decisive. Roeders supports this through its technology center and CAM support, and a test cut on a sample workpiece lets the achievable accuracy be demonstrated on the customer’s own part before purchase.
