A manufacturing system for machining comprises a machine tool and a handling cell. The machine tool is arranged for multi-axis machining and includes a tool holder and a workpiece holder, which are movable relative to each other in at least three axes. The handling cell comprises a first interface to the machine tool, which is laterally coupled to the working space, a second interface for transfer purposes, a handling unit, and at least one buffer storage, wherein the handling unit is arranged for an automated workpiece change. A manufacturing line for machining comprises at least one manufacturing system and a combined transfer and storage device.

A tool change unit includes a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base. Each arm body includes a position-returning element, a gripping element, and an actuation element. The position-returning element enables the tool arm to rotate for upward and downward moving between a first position and a second position. The gripping element functions to grip a main-axle tool or a magazine tool. The tool change unit is combinable with a power unit to form a tool change device. The power unit drives the tool change unit to do rotation or rotation and upward and downward movement.

A machine tool includes: a tool magazine that stores a plurality of tools; a spindle that holds one of the plurality of tools stored in the tool magazine; a glossiness measurement unit that measures glossiness of a tapered outer surface of a taper shank of each of the plurality of tools; a deterioration determination unit that determines whether or not the tapered outer surface is deteriorated on the basis of the glossiness measured by the glossiness measurement unit; and a notification unit that notifies an operator of deterioration of the tapered outer surface if it is determined by the deterioration determination unit that the tapered outer surface is deteriorated.

This tool exchange device for a machine tool uses an exchange arm to exchange tools between a processing area and a tool accommodation area which are partitioned by a partition wall provided with an opening and a shutter capable of opening and closing the opening. In the tool exchange device, an imaging device is used to capture an image of a tool in the tool accommodation area, the length of the tool is calculated from the captured image of the tool, the opening width of the shutter is determined in accordance with the length of the tool, and the shutter is opened to the determined opening width.

A feeding device for a rotatable wheel magazine of a machine tool is proposed. The feeding device includes a manipulator for changing and inserting tools on the wheel magazine, wherein the manipulator is movably arranged along the first direction of movement and has at least one movable tool holder. A tool input unit is provided with tool input positions for tools to be introduced and/or replaced in the wheel magazine. The manipulator for changing and inserting tools on the wheel magazine is moved along the first direction of movement, making refilling of the wheel magazine easy and efficient.

A tool changer includes a holding member having a tool change arm, a rotating mechanism for rotating the holding member, a forward/backward moving mechanism for moving the holding member forward and backward, and a controller controlling the mechanisms. A zero return controller determines whether the tool change arm is holding tools. When it is not holding tools, the tool change arm is rotated to a predetermined non-interference angle, the tool change arm is translated to a forward/backward movement zero point, and the tool change arm is rotated to a rotation zero point. When it is holding tools, the tool change arm is translated to a forward end, the tool change arm is rotated to position it on an expected path, and the tool change arm is moved along the expected path, thereby moving the tool change arm to the rotation zero point and the forward/backward movement zero point.
