An angle head attachment of a machine tool may include a main shaft, a bevel gear, a spindle and at least one idle gear module. The main shaft may be rotated with respect to a first direction. The bevel gear may be configured to convert a rotary force of the main shaft into a rotary force rotated with respect to a second direction substantially perpendicular to the first direction. The spindle may be rotated with respect to the second direction by the rotary force of the bevel gear. The idle gear module may be interposed between the bevel gear and the spindle to transmit the rotary force of the bevel gear to the spindle. The rotary force of the main shaft may be transmitted to the spindle through the at least one idle gear module so that the angle head attachment may have a slim structure.

An apparatus configured to convert a rotary machine to a non-rotary machine is provided. The apparatus may include a tool body that engages a rotary head of a CNC mill and a rotation restraint member that is fixed at a stationary position relative to a rotational axis of the rotary head. An arm of the tool body may engage the rotation restraint member to prevent rotation of the tool body. A cutting tool may be coupled to the tool body such that rotation thereof is also fixed. The arm of the tool body may include an elongated aperture that allows for slight pivoting of the tool body and the cutting tool to facilitate chip removal and cutting in opposing directions. Related methods are also provided.

A fabrication system may generally comprise an x-y positioning assembly, a clamping head to receive an end effector, wherein the clamping head is coupled to the x-y positioning assembly, a z positioning assembly, a platform including a surface that is rigid and substantially planar, wherein the platform is coupled to the z positioning assembly, and a controller operably coupled to the x-y positioning assembly, end effector, z positioning assembly, and platform. Methods of using the fabrication system are also described.

The device and the corresponding method according to the invention relate in particular to a CNC machine tool and a machining method preferably for large machining patterns. The CNC machine tool may comprise a machining head 2 which may be connected to a Z-axis 1 such that it can be manually and/or automatically changed, and which may have at least two tool spindles 3 for receiving tools 4. The Z-axis 1 can be moved in a linear manner at least along two linear axial directions. The Z-axis 1 and/or the machining head 2 may have at least one axis of rotation.

The invention relates to a motor spindle comprising at least one spindle drive which can be supplied with energy and/or operating supplies via at least one feed line. This motor spindle has a fixedly installed first coupling element of a multi-coupling, to the ports of which the feed lines for transmitting energy and/or operating supplies are connected. The invention also relates to a machine tool comprising such a motor spindle, wherein the machine tool has a second coupling element of the multi-coupling. On this second coupling element, the respective complementary ports for transmitting energy and/or operating supplies are arranged.

According to a tool clamping device for a machine tool, when a draw bar is moved in the axial direction of the main shaft of the tool clamping device, a steel ball moves in the radial direction of the main shaft so as to press the inner wall of the main shaft, forming an impression on the inner wall of the main shaft. This forms an inclined surface for generating a magnification effect for magnifying a spring force.

The present invention relates to a coupling system for use at a spindle apparatus of a machine tool, comprising an energy transmission unit with a transmitter coil unit for the contact-free transmission of electrical energy to a receiver coil unit of a tool interface unit with an electrical load and a tool interface portion for accommodation in a tool support of a work spindle of the spindle apparatus, and a coupling interface unit having an interface body element attachable to the spindle apparatus and a second coupling element which is configured to be coupled to a first coupling element of the energy transmission unit by means of a releasable connection.

A device (10) for the automatic connection of a high speed spindle (40) to a numerically controlled machine is described, comprising a first connecting element (11) and a second connecting element (31), the first connecting element connection (11) comprising a first electrical contact element (14) and a first duct (12) for the passage of pressurized air; the second connecting element (31) comprising a second electrical contact element (34) configured to establish an electrical contact with said first electrical contact element (14) and electrically power the spindle at high speed (40), and a second conduit (32) for the passage of the pressurized air coming from the first duct (12); a method is also described for automatically sealing the first and second connecting elements (11, 31) of the device (10).
