In modern processing centers, inductive sensors are the components of choice for monitoring the motor spindle clamping process. Integrated into the spindle, they must be exceptionally small and offer high repeatability to ensure smooth tool changing at all times.

Baumer offers a high-performance portfolio of miniature sensors for the intelligent design of effective spindle solutions. This can either involve a classic design with three switching sensors or a smart design with one measurement sensor.

Tool change in fully automated processing centers, from removal until the insertion of the new tool in the spindle, takes less than a second. To achieve maximum system effectiveness, this process must function with ultimate reliability. The error-free functioning of the smallest inductive sensors plays a major role in ensuring this. For the processing center to function error-free, the machine control requires the following key information regarding the status of the collet chuck: open and no tool clasped, closed and no tool clasped, or closed and tool clasped. The answer to this challenge are inductive sensors. The task can be handled using either one measurement sensor or three switching inductive sensors.

In drive and clamping solutions, the sensor technology is integrated in the motor spindle. Given this confined space, the sensors must therefore be as small as possible, yet very powerful – characteristics found in the sensors from Baumer. The Swiss sensor manufacturer offers the market’s largest portfolio of miniature and sub-miniature inductive sensors with micrometer measuring accuracy.

One example is the inductive proximity sensor IFRM 03 with a diameter of only 3 mm. It is available in various lengths starting at a mere 12 mm. Yet its miniature housing contains the complete evaluation electronics that are responsible for the high-repeatability switching points as well as the precise analog measurement values. 

In addition, these industrial-grade sensors are robust, EMC-stable, and comply with the protection class IP 67. The sensors remain unaffected by heat, oily environments, and vibrations that normally occur in tooling machines.
