Spindles nowadays reach very high working speeds. Machining processes often cause considerable vibrations. These lead to poor product quality and to bearing damage to spindles and axes.
Early detection of bearing damage is essential to keep machine and spindle vibrations under control, reduce consequential costs and improve quality. This can be achieved by precise evaluation of sensor signals (vibration, temperature and optional gravity). Alarm limits can be set individually, and in the event of exceeding or dropping below them, a defined reaction can be taken at an early stage.
Artis monitoring systems indicate problems of the machine condition after a tool change at an early stage before the cutting process. When changing tools, a chip can enter the space between the tool holder and the main spindle. If this event occurs, the quality of the workpiece to be machined is often affected. Usually, the result of the chip placement is only determined at the end of the entire machining process when the workpiece is inspected. Real-time detection with Artis machine monitoring systems means avoiding all unnecessary subsequent steps and saving a considerable amount of time.
