A tool holding part holds two boring bars in a manner in which axes of the boring bars are parallel to a spindle axis. A tool change mechanism has a circular arc movement mechanism in which the boring bar moves from a tool holding position to a tool change position by at least a circular arc movement on a plane surface including an axis of the spindle in the tool change position and an axis of the boring bar positioned in the tool holding part.

Machine tool

A horizontal machining center serving as a machine tool includes: a bed; a front-side guide rail shaped to extend linearly along an upper surface of the bed and attached to the bed; and a column provided on the upper surface of the bed and fixed to the bed. The column has a facing portion arranged to face an end of the front-side guide rail in an X-axis direction in which the front-side guide rail linearly extends. The facing portion is provided with a hole through which the front-side guide rail can be inserted. By such a configuration, a machine tool with excellent workability during removal of an elongate body is provided.

A moving body guide mechanism of a machine tool includes at least two bar-shaped guide members, and sliders engaged with the two guide members, respectively, movably with respect to the guide members so that a moving body is guided along an axis parallel to a moving axis extending in a longitudinal direction of the guide members. Attaching surfaces of the two guide members or the sliders to the moving body are provided symmetrically across a plane including the axis parallel to the moving axis in such a manner that an angle formed by the attaching surfaces becomes smaller than 180&#xb0;.

Moving body guide mechanism of machine tool

Provided is a temperature control apparatus of a working machine that is inexpensive, energy-saving and capable of eliminating the temperature difference between a temperature in a room in which the working machine is installed and a temperature of a working area.

Scraping plates include: a first scraping plateattached to chains, with an end surface' thereof facing a receiving platebeing deviated from an attachment point c&#x2032; where the first scraping plateis attached to the chains, by a distance Lto an opposite side of an advance direction a of the chains; and a second scraping plateattached to the chains, with an end surface&#x2032; thereof facing the receiving platebeing deviated from an attachment point d&#x2032; where the second scraping plateis attached to the chains, by a distance Lsmaller than the distance Lof the first scraping plateto the opposite side of the advance direction a.

Chip discharge device of machine tool

A chattering vibration inhibiting mechanism capable of inhibiting chattering vibration of a machine tool without increasing weight nor requiring a time-consuming adjustment work is provided. A box-shaped package bodyattached to a spindle head, a supporting memberdisposed to bridge between front and rear wallsin the box-shaped package body, and a dampercomposed of an elastic memberand a weightsupported by the supporting memberare provided.
