Spindle monitoring and recording unit

Maintenance of spindles is costly because the running hours and operating conditions largely depend on the type of operation. It is difficult to know when the spindle is near the end of its life period. The Spindle Monitoring and Recording Unit (SMRU) is designed to register the temperatures, rotational speed and running hours. It is meant as a tool for maintenance planning and to record if the spindle has run outside the normal operating conditions. The SMRU is a black box that can be either integrated into the spindle or bolted to it. Therefore, the SMRU can provide a means of identification of the spindle. It can hold specific information about the spindle as to its use, maintenance history and its identity. A fleet of SMRUs can be managed in a network.

Crash detection system for spindles

CDS is used to monitor the machine conditions and events of spindles. A three-axial vibration sensor measures the vibrations in the spindle head. The vibration information is grouped into 8 channels.

The spindle speed is either derived from an existing sensor or measured by an additional speed sensor and is classified into 6 channels.

Three temperature sensors measure the temperature of the two main bearings and the driving motor. For each of the 48 channels (8 vibration channels times 6 speed channels), the minimum, maximum and mean of these temperatures are stored and the time of working under these conditions is summed up.

In addition, events with the maximum temperature, vibration or speed results are logged with a time stamp for later analysis in case of a spindle damage.
