MILL S/X (U) from Mikron for milling, grinding

On the customer side, the manufacturing process is crucial to meet market demands. Getting to market quickly is a daily challenge. Due to the COVID-19 crisis, the cost of raw materials has increased and producing the first part correctly is essential to reduce costs and avoid scratches. A short machining process is essential to increase productivity and efficiency.

The Micron The MILL S/X (U) three-axis and five-axis milling series are known for their precision, accuracy, high dynamics, iconic design and ergonomics. Accessibility to the machines is easy and their size is reduced whether on a stand-alone machine or associated with an automation cell. With fast processing speed, parts can be produced to meet market demands with flexible production. Automatic Machine Calibration (AMC) as standard on the series enables calibration and cooling of all machine components keeps the process stable during long milling and grinding processes.

The MILL S and X series include hybrid milling and grinding capabilities. The new machines can combine milling and pattern grinding on the same machine without any impact on its footprint or performance. The grinding setup is designed to maintain standard workpiece dimensions and clamping surface for automated processes. The laser measuring system and the dressing spindle (with adjusted RPM from 3,000 to 20,000) remain located closer to the working area for a quick and fast grinding process. In addition, the dressing spindle is installed with a slight inclination to dress any type of grinding tool without any problem.

With this two-in-one solution, the Mikron MILL S/X (U) series reduces the time and complexity of the customer’s manufacturing process. The combination of milling and grinding technologies, high machine dynamics and constant thermal stability thanks to Ambient Robust technology, guarantees high precision and a fast return on investment for high-quality parts. The dressing spindle is equipped with an Acoustic Emission (AE) sensor to track and visualize the signal on the Heidenhain control during tool dressing. The machine can be equipped with an additional AE sensor to monitor grinding operations and further optimize the process. Thanks to the additional AE sensors on the machine table, operators can adapt their process even more thanks to the automatic tool part detection cycle. This cycle, developed by GF Machining Solutions, avoids air grinding by sensing exactly when the grinding tool touches the part to start the process in optimal conditions.
