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.

The invention primarily relates to a system (10) for detecting a total or partial obstruction of at least one internal fluid pipe (11) of a tool (12), characterised in that said system (10) comprises: a pneumatic system (13) that is intended to be connected upstream of said internal pipe (11) of said tool (12), a pressure source (16) that is connected to said pneumatic system (13) by means of a solenoid valve (17), and a control unit (22) that is configured to open said solenoid valve (17) so as to pressurise said pneumatic system (13), and then to close said solenoid valve (17) so as to let said pneumatic system (13) be emptied freely by means of said internal pipe (11), and to detect an obstruction state of said internal pipe (11) depending on an analysis over time of a change in the pressure in said pneumatic system (13).

A motor drive system enabling detection of cutting fluid deposited at a housing of electronic components. A housing holding electronic components of a motor drive system has top faces slanted with respect to the horizontal plane so as to guide the deposited cutting fluid. The housing further includes storage parts collecting the cutting fluid guided along the top faces. The storage parts may be graduated so as to enable the collected amount of the cutting fluid to be measured. The storage parts may be configured to be detachable from the housing.

The present invention relates to a transport device (100) for transporting one or more handling devices, each for handling a pallet (300) and/or a workpiece (1) on a machine tool (1000) which is set up on a base surface for machining the workpiece (1), wherein the transport device (100) is freely movable on the base surface for positioning the one or more handling devices relative to the machine tool (1000), in particular within a region in front and/or next to the machine tool (1000) and/or in front and/or next to a working space of the machine tool (1000).

A tool accessory used to apply different volumes of a cutting fluid to the tap under CNC control by causing the machine to undergo different pump cycles in which the rotational speed of the tool is increased above the tapping rotated and then quickly returned to the tapping rotation. The tool includes a tapping head, a reservoir filled with cutting fluid, a centrifugal force-reactive pump and at least two discharge nozzles. The pump includes a plurality of biased piston springs that are forced outward and store centripetal force when the tool is rotated at speeds above normal tapping speed. When the rotational speed of the tool is reduced, the piston springs overcome the centrifugal forces and force cutting fluid through the discharge nozzles. The volume of cutting fluid discharged is controlled by adjusting the viscosity of the cutting fluid, the tool's maximum speed, by using different size discharge nozzles, and by using different pump cycles.

Provided is a cutting fluid tank for a machine tool, with which the operator's time and effort for cleaning are reduced and the maintainability is enhanced, without entailing an increase in size. In a tank body, a cutting fluid flow channel having a spiral shape and extending from a tank center region to a tank outer peripheral region is formed by a flow channel forming plate. An inflow port into which a cutting fluid from inside a machining chamber flows is provided at an outer peripheral region of the lid, whereas an outflow port to take out the cutting fluid in the tank body to an outside is provided at a center region of the lid. A pump to pump up and supply the cutting fluid to the machining chamber is provided at the outflow port.
