A chip discharge device for a machine tool is provided that has a simple structure, enables automatic replacement of tools, and is suitable for a machine tool in which a spindle head is turned about an axis of turning that is not parallel to the center axis of the spindle. A suction pipeon the first support member side is disposed in parallel to a first axis of turningto be centered on the axis of the through holeof a first support member. A right end of the suction pipeon the first support member side is fixed by bolts to a left end surface of the spindle head. An outer circumferential surface of the left end of the suction pipeon the first support member side is connected to be able to relatively rotate to an inner circumferential surface at the lower end of a second communicating pipe. A seal mechanismis provided in the connection portion, preventing the external air from being sucked into the second communicating pipe

Chip discharge device for machine tool

Machine tool simplifying maintenance, reducing manufacturing costs, and enabling high precision machining. The machine tool is equipped with: a bed furnished with a rectangular base, right and left sidewalls provided standing either side of the base, and a rear sidewall provided standing along the back of the base; a table disposed in the space surrounded by the three sidewalls; a first saddle shaped in the form of a rectangular frame shape, provided free to shift back and forth supported on the tops of the left and right sidewalls; a second saddle penetrated by a perpendicular through-hole and arranged free to shift sideways inside the first saddle frame; and a spindle head arranged free to shift perpendicularly inside the through-hole in the second saddle; and a main spindle arranged over the table and supported by the spindle head free to rotate centered on its axis.

Machine tool

The present invention provides a machine tool capable of reducing residual vibration occurring at the location time, thereby achieving responsiveness to a recent demand for higher acceleration/deceleration speed. The machine tool is configured such that a columnis fixed on a bed, a spindle headfor supporting a spindleis disposed on a front face' of the columnto be movable in a Z-axis direction, and a pair of right and left Z-axis ball screws (spindle drive shafts)for driving the vicinity of the gravity center of the spindle headis disposed on the front face&#x2032; of the columnto be symmetrical to each other with respect to a plane that includes an axis C of the spindle headand is parallel to a Y axis, thereby driving the vicinity of the gravity center of the spindle head

There is provided a machining center capable of simplifying a driving force transmitting mechanism and restraining occurrence of noise and vibration. A machining center having a turret headwith a plurality of tools on a turret baseincludes one tool drive motor for each tool, the tool drive motor rotary driving the corresponding tool independently.

The present invention provides a machine tool whose width dimension is not increased even when it includes a tool magazine. The present invention includes: a bed; a saddle disposed on the bed to be movable in a forward and backward (Y-axis) direction in a front view of the machine tool; a table disposed on the saddle to be movable in right and left (X-axis) direction; a column fixed on the bed a spindle head disposed on the column to support a spindle and movable in a vertical (Z-axis) direction; an automatic tool changer disposed on a back face side of the column, wherein the column has an opening which allows the back face side and a front face side of the column to communicate with each other, and the automatic tool changer replaces a tool on the spindle side by a tool on a tool magazine side through the opening.

The present invention provides a machine tool capable of enhancing approachability to a spindle to improve work efficiency even when it includes a workpiece changer. The present invention includes: a bed; a saddle disposed on the bed to be movable in a forward and backward (Y-axis) direction in a front view of the machine tool; a table disposed on the saddle to be movable in a right and left (X-axis) direction; a column having a shape of a gate bridged over a travel range of the table and fixed on the bed; a spindle head disposed on the column to support a spindle and movable in a vertical (Z-axis) direction; a workpiece changer that turns a workpiece together with a pallet or turns the workpiece independently, for workpiece replacement, between a workpiece standby position set on a back face side of the bed and the table placed at a workpiece change position, the workpiece changer being disposed so as to set the workpiece change position at a position under the column.

The present invention provides a machine tool capable of achieving a higher feed rate of a spindle and weight reduction while ensuring necessary stiffness of a column. The present invention includes: a bed; a saddle disposed on the bed to be movable in a Y-axis direction in a front view of the machine; a table disposed on the saddle to be movable in an X-axis direction; a column having a shape of a gate that is bridged over a travel range of the table and has right and left legs fixed on the bed and a beam connecting tops of the right and left legs; and a spindle head disposed on a front face of the beam to be movable in a Z-axis direction.

The present invention provides a chip discharging device for a machine tool, which is capable of making the entire machine small by minimizing a protruding amount of the chip discharging device toward the backside of the machine, and making an install space thereof small. A columnis arranged and fixed on an upper surface of a rear wall portionof a bed, the rear wall portionis arranged to deviate upward, rear wall inclined surfacesand' rising obliquely upward are formed on a bottom portion of the rear wall portion, a storage tankfor storing coolant is arranged inside a rectangular frame of the bed, the storage tankhaving a form which extends through a space beneath the rear wall portionto the backside of the machine and further stands up obliquely upward along the rear wall inclined surfacesand&#x2032;, and a chip conveyoris arranged inside the storage tankfor conveying chips to the backside of the machine.

Chip discharging device for machine tool

The present invention provides an arrangement structure of a machine tool which is capable of compactly arranging electrical wires and pipes for coolant and the like without impairing support stiffness for a column, and simplifying the arrangement structure, while adopting a column fixing structure. In the present invention, an arrangement structure of a machine toolincludes a bed, a tablearranged on the bedto be movable in a forward and backward (Z axis) direction, a columnfixed upright on the bed, a saddlearranged on a front surface of the columnto be movable in a left and right (X axis) direction, a spindle headarranged on a front surface of the saddleto be movable in an up and down (Y axis) direction, a spindlesupported by the spindle headto horizontally face a front side of the machine, a wire supply portion arranged on the columnside, and flexible tubesfor spindle side electrical wires having flexibility and arranged on a front side of the column, the flexible tubesfor the spindle side electrical wires connecting the wire supply portion and the spindle head

Arrangement structure of machine tool
