Abstract
A tool holder system for stationary or rotatable tool holders in machine tools with manual or automatic tool change, has a tool holder provided with a mechanism for locking the tool head onto clamping surfaces, and integrated liquid coolant supply and a compressed air supply to the clamping surfaces. At the clamping end of the tool holder, a checkvalve is provided in the air supply passage to block incursion of liquid coolant even at high pressures of the latter and thus prevent corrosion and damage which may result from such corrosion.
Claims16
A tool-mounting assembly comprising:
- a tool holder for a machine tool formed with a receiver for a tool head;
- a tool head replaceably fitted on said receiver;
- a coupling mechanism on said tool holder at said receiver for engaging said tool head and clamping same on said receiver;
- a liquid coolant passage formed in said tool holder and communicating with said tool head at said receiver for delivering a coolant to a machining location at an elevated pressure;
- means forming a pressurized air passage in said holder opening in a region of said receiver for delivering air under pressure to a region at which said tool head is coupled to said receiver for carrying away chips and other contaminants on surfaces of said tool holder to be contacted by said tool head;
- and
- a checkvalve in said pressurized air passage on said tool, holder to prevent flow of said coolant into said pressurized air passage.
