Abstract

The invention relates to a spindle for a machine tool, in particular a motor spindle having a housing (2) for accommodating an electric motor (3) and a shaft (6) which can be driven by the latter, in particular having a tool holder for a tool for machining workpieces, wherein at least one data acquisition element (8) for recording operating and/or state data of the spindle is provided, and wherein the data acquisition element is in the form of a radio chip and can be read by radio using a read element (9).

Claims

1. A motor spindle for a machine tool, the motor spindle having a housing for holding an electric motor and a shaft driven by the electric motor, having a tool holder for a tool for workpiece machining, and having at least one data acquisition element in order to receive at least one of operating data and state data relating to the motor spindle, wherein the at least one data acquisition element comprises a radio chip readable by radio via a read element;

wherein the radio chip is within the motor spindle; and

wherein the read element is arranged within the housing of the motor spindle for reading the radio chip within the motor spindle.

2. The motor spindle as claimed in claim 1, wherein the radio chip does not have its own power supply, and the radio chip is supplied with appropriate power for reading via the radio waves of the read element.

3. The motor spindle as claimed in claim 1, wherein the read element can be connected to a machine controller for the machine tool.

4. The motor spindle as claimed in claim 1, wherein the read element is intended to read the radio chip of the motor spindle and to read the radio chips of adjacent spindles.

5. The motor spindle as claimed in claim 1, wherein an external read element is provided in order to read the radio chip within the motor spindle.

6. The motor spindle as claimed in claim 5, wherein the radio chip has a data area which can be read only by the external read element and not by the read element arranged within the housing of the motor spindle.

7. The motor spindle as claimed in claim 5, wherein the motor spindle has a plurality of radio chips, some of which can be read by the read element arranged within the housing of the motor spindle, and some of which can be read by the external read element.

8. The motor spindle as claimed in claim 1, wherein the read element has a plurality of separate radio signals, which can be selected, in order to separately read different radio chips.
