A machine tool is provided with a main shaft configured to have a tool fitted to a distal end portion thereof, a tool magazine for holding a plurality of tools, a tool exchanging arm for exchanging tools between the tool magazine and the rotary main shaft, and a table for attaching a workpiece, wherein the machine tool machines the workpiece by causing the main shaft and the table to move relative to one another in accordance with a machining program, and wherein the machine tool: is provided with an image capturing device for capturing an image of the tool fitted to a tool holder, and an interference checking device which uses the machining program, and shape data relating to the workpiece, the tool, and the machine tool to simulate machining before machining is carried out, to check for the presence or absence of interference between at least the tool and the workpiece; and acquires the shape data relating to the tool from the interference checking device, generates a two-dimensional tool model from the acquired shape data relating to the tool, compares the two-dimensional tool model with an image of the tool captured by the image capturing device, and determines that the tool is invalid if an amount of displacement between the two-dimensional tool model and the image data is equal to or greater than a prescribed threshold.

An automatic tool changer includes a cover that partitions a machining area and a non-machining area, and an opening/closing member that opens/closes an opening of the cover by turning in synchronization with rotation of a tool changer magazine. The opening/closing member includes a plate section partitions the machining area and the non-machining area at a position of the opening of the cover. In a case where the tool changer magazine performs tool replacement with respect to a tool storage magazine, the plate section closes the opening of the cover by taking a horizontal posture. In a case where the tool changer magazine performs tool replacement with respect to a main spindle, the plate section opens the opening of the cover by changing its posture from the horizontal posture to an inclined posture or a vertical posture.

The disclosure provides a method and system for milling injected cutting fluid under different working conditions. By analyzing influence of airflow fields in a milling area under different working conditions on injection of cutting fluid, an influence rule of a helical angle and a rotation speed of a cutter on the flow field is quantitatively analyzed, an optimal target distance of a nozzle, an angle between the nozzle and a milling cutter feeding direction and an angle between the nozzle and the surface of a workpiece are comprehensively determined, the nozzle is set according to a determined setting manner, and lubricating oil is sprayed to the milling area by utilizing the nozzle.

A machine tool setup changing method includes mounting a master workpiece onto a tool spindle axis, deforming a gripping part by gripping, with the gripping part of a jig, a mock clamped portion of the master workpiece mounted on the tool spindle axis, and removing the master workpiece from the tool spindle axis and mounting a tool supported on a tool support device onto the tool spindle axis, wherein the workpiece gripped at the clamped portion by the gripping part, which was deformed in accordance with the mock clamped portion, can be machined with the tool.

This machine tool comprises a machining chamber in which machining of a workpiece is performed, and a tool storage chamber in which a plurality of tools are stored. The machine tool is further provided with a partition which partitions the machining chamber and tool storage chamber from one another. The machine tool is positioned on the front side of the machining chamber, and is equipped with a first sliding door that moves in the width direction, and a second sliding door that is positioned on the front side of the tool storage chamber and that moves in the width direction. The first sliding door and second sliding door are positioned in such a manner that one of the sliding doors is positioned on the front side of the other sliding door, and when one of the sliding doors is opened, said door overlaps with the other sliding door.

The present disclosure relates to a tool magazine for a machine tool, and more particularly, to a tool magazine for a machine tool, wherein tool receiving units of a tool magazine are provided in multiple stages in a vertical turning center, such that a spindle head may easily change internal diameter machining tools and external diameter machining tools while moving in a horizontal direction and a vertical direction.

The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

The present invention relates to a machining center, and more specifically to a horizontal multi-spindle machining center, in which 2-axis (Y- and Z-axis) or 3-axis (X-, Y- and Z-axis) transfer drive units are disposed in the machining center installed to machine workpieces, in which a ram equipped with spindles is moved in the up-down, front-back, and/or left-right directions of the workpieces, in which the spindles are configured to include a plurality of spindles, i.e., 2 to 8 spindles, so that a plurality of workpieces may be machined simultaneously, and in which tool change is simultaneously performed for tools fastened to the plurality of spindles and configured to machine workpieces by using an auto tool changer (ATC), so that tool change speed may be improved and thus manufacturing efficiency may be improved.
