摘要:
A monitoring procedure and a monitoring installation for machine tools with a motor-driven work spindle and a separate protection device. The actual mass inertia moment of a tool fitted into the work spindle is determined by measurement and compared with a mass inertia moment calculated from the data of the tool. In addition, a predetermined parameter of a tool fitted into the work spindle is compared with that of the maximum parameter for the tool which is dependent on the strength of the protection device. The work spindle will be driven at the predetermined desired speed of rotation only if the actual mass inertia moment agrees with the calculated mass inertia moment and the predetermined parameter is smaller than or equal to the maximum parameter predetermined by the strength of the protection device.

The invention relates to a machine tool 101 comprising a plurality of operation functions and a selection device 113a-113d for selecting one or more operation functions by a user. The machine tool 101 receives data from a mobile data carrier 311 via a reception device 112, on the basis of which it may be determined which operation functions may be performed by the user. In this process, an access control device 130 grants the user access to only those selected operation functions he or she is authorized to perform.

The invention relates to an assembly rack with two side walls (10, 11) and with honeycomb plates (20) which are arranged between the side walls and connected to transverse profiled rails (15, 16). In such an assembly rack, a reliable shielding against electromagnetic interference should be safeguarded at low cost. This achieved according to the invention in that two transverse profiled rails (15, 16) together with one honeycomb plate and with two lateral profiled rails form an EMI-shielded, self-contained sub-assembly which can be previously assembled, and in that the assembly rack comprises at least two such sub-assemblies (12, 13) which are connected to the side walls with fastening elements in an EMI-shielded manner.

A universal machine tool having a workpiece slide movable on a machine bed by means of a motor for the workpieces to be machined and a machining unit which is movable about a plurality of axes by means of a motor. The machining unit includes a motor-driven work spindle for receiving the machining tools. To enable turning operations in addition to milling and drilling operations with high cutting performance in a single clamping position, according to the present invention, the workpiece slide is provided with at least one rotatable workpiece accommodation and an associated rotary drive means. The rotary drive means can drive the workpiece accommodation for carrying out turning operations on the workpiece to be machined.
