Abstract
The invention therefore provides a tool holder for tools supplied with coolant or lubricant, especially rotating tools such as boring or milling tools, with an internal duct system for passing coolant or lubricant to the shank of the tool. To enable particularly flexible use of machine tools, the tool holder is equipped according to the invention with a lubricant reservoir which is integrated into the tool holder and which is preferably fillable and pressurizable, which during operation of the tool can be decoupled from a coolant or lubricant source and supplies the tool controllably with coolant and lubricant via a metering unit.
Claims26
A tool holder for rotating tools, comprising:
- an internal duct system configured to supply at least one of coolant and lubricant to a tool held by said tool holder;
- and
- a fillable and pressurizable reservoir configured to receive at least one of a coolant and lubricant, said reservoir integrated into the tool holder or constructed in one piece together with the tool holder;
- a metering unit configured to connect at least one of an external coolant or external lubricant source with said internal duct system;
- wherein the tool is configured to be decoupled from said at least one of external coolant and external lubricant source during operation of the tool, and wherein said metering unit is actuatable as a function of the rotation of the tool holder;
- wherein the metering unit is actuatable as a function of at least one of rotational speed and temperature during rotating operation of the tool.
A process for cooling or lubricating a rotating tool chucked in a tool holder, wherein at least one of a coolant and a lubricant housed in a reservoir integrated into the tool holder is supplied directly to the tool in its chucking position during rotating operation of the tool as a function of at least one of rotational speed and temperature via a duct system integrated into the tool holder and connecting the reservoir with the chucking point of the tool.
