Claim 12:
13. A machine tool system having a machine tool which comprises a spindle which can be driven in rotation for the purpose of metal-cutting machining workpieces, having a plurality of tools including tool heads, which are clamped in chucks and can be coupled to the spindle, and having a balancing device for balancing the tool heads, wherein the machine tool system comprises a data memory in which an associated balancing log is respectively stored for the system-associated tool heads and a controller which reads out balancing data from the balancing log for a tool head which is coupled to the spindle and compares said data with one or more parameters of the metal-cutting processing for which this tool head is provided or compares said data with at least one general balancing parameter, wherein the machine tool system is preferably configured in such a way that it rejects a tool head if there is no balancing data available for this tool head; and
wherein the balancing log documents at least one balancing data item, preferably a plurality of balancing data items and ideally at least all of the balancing data items with the exception of two of said items mentioned below: data of the last balancing process, data on the permissible rotation speed, data on the residual unbalance which is present, static unbalance with or without data on the vehicle mass, dynamic unbalance with or without data on the vehicle mass, such as a combination of the static unbalance with torque unbalance, balancing quality with or without data on the vehicle mass, quotient of the vehicle mass/residual unbalance, metal-cutting parameters and milling parameters balanced/not balanced, good or bad state of balance.
