Tool cutting edge adjusting head, method of operating same and correcting tool cutting edge wear

An adjustment head intended and arranged for use in a working space of a CNC machine having a base station arranged and intended for information exchange with a measuring probe or bore gauge connected to a control of the CNC machine, the adjustment head comprising:

• a first function module and a second function module, the first function module being divided into a power supply module and a data transmission module, wherein the power supply module and the data transmission module have an integrated coolant duct for passing coolant to at least one machining point of the machining module,
• the second function module comprising, a machining module for receiving at least one tool, the machining module comprising a tool adjustment device for adjustment the tool or its cutting edge/s in a radial and/or an axial direction and/or in an angular orientation of the tool-based on instructions from the controller,
• wherein the first function module includes a first section of the integrated coolant duct and the second function module includes a second section of the integrated coolant duct,
• wherein the power supply module supplies electrical power to components of the adjustment head, including the data transmission module and the tool adjustment device, and
• wherein the data transmission module is arranged and intended for exchanging information concerning at least the adjustment of the tool accommodated in the adjustment head with the base station of the measuring probe or bore gauge in the working space of the CNC machine.
