A cutting fluid tank includes: a fluid ejection apparatus configured to eject fluid toward cutting fluid containing chips and to be capable of varying at least one of a direction and a position of ejection with time in an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The fluid ejection apparatus includes an ejection head having an ejection port rotatable about an axis of rotation. The ejection port is at a twisted position with respect to the axis of rotation, and the ejection head is rotated by a reaction force of the fluid ejected from the ejection port. Part of the cutting fluid stored in the cutting fluid tank is used as the fluid to be ejected from the ejection port.

A cutting fluid tank includes a variable flow restricting device configured to restrict a flow of cutting fluid containing chips into an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The variable flow restricting device includes variable partitioning members which constitute at least part of a partitioning that partitions a flow channel of the cutting fluid containing the chips. The variable partitioning member is pivotably and the flow channel varies in association with the pivotal motion of the variable partitioning member.

Embodiments relate generally to milling machines and milling techniques, and more particularly, to apparatuses, milling machines and methods to control automatic loading and/or unloading of work pieces in relation to the adverse milling machine environments. In one embodiment, an apparatus includes a subset of guide members constituting a staging region, a loader member configured to impart a loading force unto the work piece to transition the work piece from the staging region, and an effector coupled to the loader member. The effector is configured to apply a cleaning force to a path in a first interval of time and is configured further to transfer the loading force from the loader member to the work piece in a second interval of time, and an alignment device configured to align the subset of guide members and the effector to form a portion of the path in a first mode.

The invention concerns a method for the chip-removing generation or machining of internal gear teeth on a workpiece which is rotatable about its rotary axis and radially delimits a free space that extends axially to one side beyond the internally toothed region and whose radial width narrows in the direction of its axial extension in at least one location. An externally toothed tool which is driven in rotary movement about its axis of rotation is brought from the opposite side into rolling engagement with the internally toothed region with the rotary axes crossed at an angle. Through the application of a mechanical force, the chips which are produced in the process and which are subject to a centrifugal force are caused to change their movement in the zone of narrowing width in a manner directed against the origin of the centrifugal force.

A machine tool with a chip evacuation device according to the present invention is provided with a cleaning mechanism for cleaning a part or the whole of the chip evacuation device and a control unit configured to control respective operations of the chip evacuation device and the cleaning mechanism in association with each other. By using an electric motor, such as a synchronous motor capable of position control, as a power source for the chip evacuation device, the respective operations of the chip evacuation device and the cleaning mechanism can be associated with each other to effectively clean the chip evacuation device.

A chip discharge device of a machine tool includes a coolant tank storing coolant which is supplied to and dropped from a machining point, and a chip conveyor discharging chips which are generated at and dropped from the machining point, to an outside of the machine tool. A bottom wall of the coolant tank is inclined in a chip discharge side by mounting the coolant tank to the bed.
