Monitoring tool clamping distance

Intelligent drive and clamping solutions where the sensors is integrated into the motor spindle are becoming increasingly common as an innovation driver on machine tools. The sensors needed for fast, smooth tool changes are available in ever smaller and more intelligent variations. These can be easily integrated into the clamping technology, regardless of whether it is activated electrically, hydraulically or pneumatically. With sensors and position measuring systems from Balluff you monitor the clamping and releasing process of the tools directly in the motor spindle.
Using the clever combination of pressure sensors or diverse redundant linear measurement systems based on different technologies, you can realize an enhanced safety level for the entire system.

Digitizing the motor spindle with IO-Link

Using the new IO-Link sensor and measuring systems you can easily incorporate the clamping technology for the motor spindle into the controller or digital network and digitize the motor spindle. This is accomplished using the open IO-Link standard, which enables fieldbus-neutral communication from the sensor/actuator level to the infrastructure of the Industrial Internet of Things (IIoT).
The future-oriented IO-Link technology makes your motor spindle more intelligent and ready for digitizing and the IIoT.

Application examples

  • Monitor tool clamping position

    Monitor tool clamping position

    The solution

    Using three inductive sensors three conditions can be checked without non-contact and wear-free: unclamped, clamped without a tool, and clamped with a tool.
    Since the sensors are installed at a defined distance from each other, this type of clamping distance monitoring is especially useful for larger strokes.

    The features

    • Simple to integrate: small form factors
    • Highly reliable: extremely rugged, high protection rating

  • Monitoring tool clamping distance with inductive distance sensors

    Monitoring tool clamping distance with inductive distance sensors

    The solution

    If your clamping system has a conical external geometry, it is possible to detect movement transverse to the sensor axis also using an inductive distance sensor.
    Such an arrangement is considered the classic solution for continuously monitoring measured clamping distance.

    The features

    • Choose IO-Link or analog interface, flexible processing
    • Position indicating target, can be used as needed depending on the application
    • Simple construction, small footprint

  • Monitoring tool clamping distance with inductive positioning systems

    Monitoring tool clamping distance with inductive positioning systems

    The solution

    Using linear position measurement you can realize clamping distance monitoring even when the clamping mechanism rotates. The inductive positioning system detects the position of a metallic disc which moves past the sensor from the side. Measuring sensors for various travel distances are available depending on the requirements.

    The features

    • Choose IO-Link, switching points or analog interface, flexible processing
    • Temperature output, for diagnostics
    • Different measuring ranges using the same technology
    • Simple position indicating metal target which can be embedded in the clamping system
