A machine tool is equipped with a second supply pipe having elasticity and having one end side fixed to a spindle head and the other end side fixed to an arm portion, a cover provided within a machining area, and rollers. When the spindle head is moved in a direction to come close to the arm portion, the second supply pipe is bent and then a portion of the second supply pipe is brought into abutment against the cover. The rollers are provided at a portion of the cover against which the second supply pipe is brought into abutment, and are configured to reduce friction between the cover and the second supply pipe when the second supply pipe moves relative to the cover in an abutment state against the cover.

A numerical-control machine tool is provided and includes a load-bearing beam which extends horizontally, has two axial ends resting in sliding manner on two lateral shoulders that rise from a basement and extend horizontally side by side so as to define a longitudinal corridor orthogonal to the longitudinal axis of the beam; a spindle-holding carriage which is movable on the load-bearing beam parallel to the longitudinal axis of the beam; a spindle-holding shaft which is fixed to the spindle-holding carriage in a vertical position, and is movable on the spindle-holding carriage parallel to its longitudinal axis; a front wall and a rear wall that close the two ends of the longitudinal corridor; an upper cover which closes the longitudinal corridor at the top; and an ambient conditioning unit which is adapted to bring and maintain the temperature of the air present inside the machining chamber around a given target value.

Machine tool including a workpiece carrier assembly including a workpiece carrier for supporting a plurality of workpieces, the workpiece carrier assembly being supported on a workpiece carrier support for horizontal movement in a first direction parallel with a horizontal Z axis, a tool carrier configured for carrying a plurality of tools corresponding to the plurality of workpieces and for machining the workpieces, the tool carrier being supported on a tool carrier support for horizontal movement in a second direction parallel to a horizontal X axis, the X axis being perpendicular to the horizontal Z axis, where the tool carrier is displaceable on the tool carrier support in the second direction between an operative position in which the tools are arranged for the contacting the workpieces and an inoperative position in which the workpieces are not contactable by the tools, where the workpiece carrier is arranged to be rotatable around an axis parallel with the X axis, and where the workpiece carrier includes a workpiece support area for supporting the workpieces and arranged substantially in parallel with the X axis.

A live tool system having a live tool and a collar surrounding a rotating shaft or a rotating cutting tool of the live tool. The collar houses at least one sensor capable of monitoring an operating condition proximate to the cutting tool during a cutting operation. Example operating conditions including temperature and vibration. The system also includes a wireless transmitter in communication with the at least one sensor for transmitting a signal for use by a machining center controller.

A machine tool has a splash guard and a guiding section. The splash guard has a first sidewall portion on which an end portion of a telescopic cover abuts, a slope portion slanting from the first sidewall portion along an expansion and contraction direction of the telescopic cover, a second sidewall portion perpendicularly extending downward from the slope portion, and a bottom portion horizontally extending from the second sidewall portion more inward than a lower end of the slope portion in the splash guard. The guiding section is disposed more inward than the lower end of the slope portion in the splash guard and configured to guide the cutting fluid falling from the slope portion, toward the bottom portion.

A levelling machine includes a pair of spaced apart rail assemblies, a gantry assembly and a face mill assembly. The spaced apart rail assemblies define an x axis. The gantry assembly is moveably attached to the pair of spaced apart rail assemblies whereby the gantry assembly defines a y axis. The gantry assembly is moveable in the x axis along the pair of spaced apart rail assemblies. The face mill assembly is moveably attached to the gantry assembly and is moveable in the y axis along the gantry assembly. The face mill assembly has a plurality of saw blades, the saw blades being generally in an x-y plane defined by the x axis and y axis. The saw blades have a plurality of teeth that extend downwardly generally in a z axis. The face mill assembly is moveable in the z axis.

An automatic milling machine mills a gasket. The automatic milling machine controls the position of a cutter head relative a table. The automatic milling machine rotates the gasket with a motor. Parameters of the motor are monitored to determine the amount of rotation of the gasket.

A workpiece replacing apparatus delivers a pre-machined workpiece into an intra-machine space inside a machine tool from an extra-machine space outside the machine tool, and delivers a workpiece machined by the machine tool to the extra-machine space from the intra-machine space. The workpiece replacing apparatus includes a secured cover, an arm device, and a movable cover. The secured cover is secured to a securing member of the machine tool. The secured cover defines a partition between the intra-machine space and the extra-machine space. The secured cover is provided with an opening. The arm device delivers the workpieces between the intra-machine space and the extra-machine space through the opening. The movable cover is integral with the arm device or in engagement with the arm device such that the movable cover is operable in conjunction with operation of the arm device. The movable cover closes the opening, with the arm device located in the extra-machine space.

A pallet changing apparatus which adopts a table 4 that is able to move back and forth in relation to a turning shaft 1 and has a oscillating portion 41 for placing workpieces W, W by way of pallets P, P so as to oscillate freely by a rising portion 42 at the leading end of the table, and a bridging extending portion 31 which bridges a supporting portion of pallet P or P in a pallet changing arm 3 with both sides of the turning shaft 1 forming a shape of covering across the upper side of the rising portion 42 at a stage of the table 4 transferring pallet P.

A pallet changing apparatus adopting a table 4 capable of moving back from and forth for a side of a turning shaft 1 and having an oscillating portion 41 for placing workpieces W, W by means of pallets P, P so as to oscillate freely by a rising portion 42 at the leading end of the table 4, wherein the turning shaft 1 covers a turning supporting portion 11 at its lower end side and turns together with a pallet changing arm 3 and moves freely in a vertical direction, and an insertion and removal hole 20 is provided, at the covering region, and allows the rising portion 42 to be inserted into the insertion and removal hole 20 and removed from the insertion and removal hole 20.
