A collar member is for a collar assembly of a cutting system and method. The cutting system has a spindle and a cutting tool coupled to the spindle. The collar assembly includes a number of components and a gas flow system having a number of gas flow delivery apparatus and a number of conduits. The collar member includes a support portion structured to be coupled to the spindle, and a chamber portion extending from the support portion and being structured to be coupled to each of the number of components, the number of gas flow delivery apparatus, and the number of conduits. The support portion has a side portion having an edge portion defining a thru hole in order to form a passageway from an interior of the support portion to an exterior thereof.

Proposed is a lubrication system, in particular a single-duct minimum quantity lubrication system, having an aerosol generator, a spindle, a tool clamper arranged on the spindle and a rotary feedthrough arranged on the side of the spindle located opposite the tool clamper, the tool clamper, the spindle and the rotary feedthrough are penetrated by a duct, in the duct is arranged a spindle tube which improves the transport of aerosol, in particular the transport of lubricant particles and/or coolant particles, above all inside the spindle or motor spindle. Further, the spindle tube is mounted in the duct in an electrically insulating manner and/or in that the spindle tube is produced from a material that is not electrically conducting and/or in that the spindle tube and/or the duct is/are provided with at least one electrically insulating layer for coating the spindle tube and/or the duct in an electrically insulating manner.

A lubricating system with an aerosol generator, a spindle, a tool clamper arranged on the spindle, and a rotary feedthrough arranged on the side of the spindle lying opposite the tool clamper, a duct runs through the tool clamper, the spindle and the rotary feedthrough. A separate aerosol generator feeds aerosol into an aerosol line to a tool via the rotary feedthrough, spindle and tool holder to transport lubricant particles and/or coolant particles inside the spindle or motor spindle. A spindle tube is arranged in the duct and is mounted non-rotatably on a non-rotating portion of the rotary feedthrough and extends at least through a portion of the spindle in the direction of the tool clamper, and the aerosol generator is connected to the spindle tube, such that aerosol is guided through the spindle tube in the direction of the tool clamper and/or a tool clamped by the tool clamper.

A grinding tool with a coolant supply device for a machine tool and such a coolant supply device. The coolant supply device for the grinding tool has a main body with engagement portions or holes and a line unit for redirecting coolant to a predeterminable processing area of the grinding tool. Using a clamping device, it is possible to releasably secure the coolant supply device to the shaft of the grinding tool. As a result of the attachment of the coolant supply device on the grinding tool, it is possible to tap the coolant of the machine tool via an additional valve device on the connector ring of the machine tool from the standard cooling circuit and supply it to the grinding location in a predeterminable processing area of the grinding tool.

A machining thermostatic control system and method of using the same are disclosed. The system comprises a detecting unit, a processing unit and at least a cooling unit. The detecting unit is used for detecting the temperature distribution of a workpiece. The processing unit is coupled to the detecting unit and is used for processing the temperature distribution for obtaining a position of maximum hot spot of the workpiece. The cooling unit comprises a head which is provided for discharging cooling fluid and a plurality of blades which are angle-adjustably mounted to the head. The blades are coupled to the processing unit and the angle of blades are controlled by the processing unit for enabling the cooling fluid to flow toward to the position of maximum hot spot position.

A fluid ejection device is equipped with a robot hand, which is attached to a distal end of an arm of an articulated robot, and having ejection holes therein for ejecting a cutting fluid toward a tool holder or a tool, and a controller adapted to control joints of the articulated robot, in such a manner that the robot hand moves along an axial direction (Z-direction) of a spindle in synchronism with a feeding operation by which the spindle is moved along the axial direction (Z-direction) of the spindle.

A robot system which can adjust the position of a coolant nozzle at a lower cost, that is, a robot system which comprises a robot, a robot controller which controls the operation of the robot, and a notification part which notifies the type of the workpiece which is processed by the machine tool to the robot controller. The robot controller determines the target position of the coolant nozzle with respect to the workpiece to be processed based on the type of the workpiece which is obtained from the notification part and makes the coolant nozzle move by the robot so as to place the coolant nozzle at the target position.

A method and apparatus for directing a coolant stream for use with a computer numerically controlled (CNC) machine tool includes a nozzle pivotably mounted on a machine tool. The position of the nozzle is automatically adjusted using information available in the CNC machine control program and the part program (i.e. G-Code) to determine where to direct the coolant nozzle at each instant in time. Integration with the machine control program allows the coolant delivery system to be continuously adaptive to machine position. The position of the coolant delivery system is computed by algorithms according to a user selected strategy. The strategy is specified within the control language of the machine control program (i.e. G-Code). No operator programming outside of using G-Code commands to select the desired operating mode is required to direct the coolant nozzle. The user can change operating modes while the machine is running by issuing G-Code commands.
