Abstract
A machining unit for a program-controlled machine tool. In particular, a spindle device for a program-controlled machine tool including a spindle housing; a working spindle which is mounted in the spindle housing in a rotatable manner about a spindle axis and which includes a clamping device for clamping a tool interface that is inserted in a tool receiving section of the spindle device and is configured to hold a milling or boring tool; and a sensor device which is arranged on the spindle housing and which includes at least one structure-borne sound sensor configured to detect structure-borne sounds or vibrations occurring during grinding operations.
Claims15
A spindle device for a program-controlled machine tool, comprising:
- a spindle housing,
- a working spindle rotatably mounted about a spindle axis in the spindle housing and comprising a clamping device for clamping a tool interface, which is inserted in a tool receiving portion of the spindle device and configured to hold a tool, and
- a sensor device arranged on the spindle housing at a front face of the working spindle and including at least one structure-borne sound sensor which is configured to detect structure-borne sound waves or vibrations occurring during grinding operations.
A spindle device for a program-controlled machine tool, comprising:
- a spindle housing,
- a working spindle rotatably mounted about a spindle axis in the spindle housing and comprising a clamping device for clamping a tool interface, which is inserted in a tool receiving portion of the spindle device and configured to hold a tool, and
- a sensor device arranged on the spindle housing and including at least one structure-borne sound sensor which is configured to detect structure-borne sound waves or vibrations occurring during grinding operations, and the structure-borne sound sensor is configured as an annular structure-borne sound sensor.
A spindle device for a program-controlled machine tool, comprising:
- a spindle housing,
- a working spindle rotatably mounted about a spindle axis in the spindle housing and comprising a clamping device for clamping a tool interface, which is inserted in a tool receiving portion of the spindle device and configured to hold a tool,
- a sensor device arranged on the spindle housing and including at least one structure-borne sound sensor which is configured to detect structure-borne sound waves or vibrations occurring during grinding operations, and
- a first ring element and a second ring element, wherein
- the first ring element is fixedly connected to said spindle housing,
- the second ring element is fixedly connected to the rotatably mounted working spindle, and at least a portion of the structure-borne sound sensor is arranged or held on or in at least one of the first and second ring elements, and
- an inner portion of the second ring element forms at least a part of the tool receiving portion of the spindle device.
